Chondrodiatasis in a patient with spondyloepimetaphyseal dysplasia using the Ilizarov technique: successful correction of an angular deformity with ensuing ossification of a large metaphyseal lesion. A case report. (1/147)Distraction through the physis (chondrodiatasis) is a controversial technique with unpredictable results. However, it has been used in the past for the lengthening and correction of angular deformities of long bones. We report the case of an 11-year-old patient with spondyloepimetaphyseal dysplasia (SEMD) who presented with a severe recurvatum deformity of the left proximal tibia secondary to collapse of the tibial plateau into a large metaphyseal cystic lesion. Using the chondrodiatasis technique with a percutaneously applied Ilizarov circular frame, we were able to correct this deformity. Surprisingly, healing and ossification of the metaphyseal lesion was simultaneously observed at the end of the treatment, a finding which, to the best of our knowledge, has not been previously reported.

The relationship between synovitis and bone changes in early untreated rheumatoid arthritis: a controlled magnetic resonance imaging study. (2/147)OBJECTIVE: The interrelationship between synovitis and bone damage in rheumatoid arthritis (RA) is a subject of controversy. Using magnetic resonance imaging (MRI), this study followed the bone changes in early RA and determined their relationship to synovitis. METHODS: Thirty-one patients with early RA who had swelling of the metacarpophalangeal (MCP) joints and 31 healthy control subjects with no clinical evidence of arthritis underwent MRI of the second through fifth MCP joints of the dominant hand by use of a 1.5T scanner. Coronal T1-weighted and T2-fat suppressed (FS) sequences were performed to evaluate bone edema, and gadolinium-diethylenetriaminepentaacetic acid (Gd-DTPA) pulse sequences were obtained to evaluate synovitis. Bony abnormalities were described as bone edema (low signal on T1-weighted sequences and intermediate/high signal on T2 FS sequences adjacent to the bone cortex) or as bone cysts (circular juxtacortical abnormalities with low signal on T1-weighted images and with very high signal on T2 FS sequences). Contrast and noncontrast MRI films were scored in a blinded manner, and Fisher's exact probability test was used to determine differences between groups. RESULTS: Twenty-one of the 31 RA patients (68%) had bone edema, which was seen in 43 of 124 joints (35% of joints) and 3 of the 31 control subjects had bone edema seen in 3 of 124 joints (2% of joints) (P < 0.0001). Thirty RA patients (97%) had Gd-DTPA-confirmed MCP joint synovitis, and bone edema was seen in 40 of the 75 joints with Gd-DTPA-proven synovitis (53%), but in only 3 of 49 without (6%) (P < 0.0001). CONCLUSION: MCP joint bone edema is present in the majority of patients with RA at presentation, but is seen only occasionally in normal control subjects. The fact that bone edema occurred rarely in the absence of synovitis in patients with RA suggests that bony changes in RA are secondary to synovitis. (+info)
Subperiosteal ganglion cyst of the tibia. A communication with the knee demonstrated by delayed arthrography. (3/147)We report a patient with a subperiosteal ganglion cyst of the tibia which was imaged by radiography, arthrography, CT and MRI. The images were correlated with the arthroscopic surgical and histological findings. Spiculated formation of periosteal new bone on plain radiographs led to the initial suspicion of a malignant tumour. Demonstration of the cystic nature of the tumour using cross-sectional imaging was important for the precise diagnosis. Communication between the ganglion cyst and the knee was shown by a delayed arthrographic technique, and the presence of this communication was confirmed at arthroscopy and surgically. (+info)
Clinical manifestations of AB-amyloidosis: effects of biocompatibility and flux. (4/147)BACKGROUND: Highly permeable biocompatible dialysis membranes may postpone the development of AB-amyloidosis, but the relative contribution of enhanced flux or reduced inflammation by highly biocompatible membranes and sterile dialysis fluid remains unknown. METHODS: In this retrospective investigation, 89 patients with end-stage renal disease maintained on regular haemodialysis for at least 10 years and treated with one type of dialysis membrane exclusively were selected for analysis. They were divided into three groups: low-flux, bioincompatible cellulose (I), low-flux, intermediately biocompatible polysulphone or PMMA (II), or high-flux, highly biocompatible polysulphone or AN69 (III). In addition, the patients were analysed according to the microbiological quality of the dialysis fluid, which had been tested regularly and was classified either as standard or as intermittently contaminated. The clinical manifestations indicative of AB-amyloidosis, namely, carpal tunnel syndrome, arthropathy and bone cysts, were diagnosed after recruitment. RESULTS: Clinical symptoms were most pronounced in group I, intermediate in group II, and lowest in group III. Patients treated with intermittently contaminated dialysis fluid showed a higher prevalence of AB-amyloidosis than patients with less contaminated dialysis fluid. Logistic regression analysis demonstrated that the flux characteristics of the dialyser and the microbiological quality of the dialysis fluid as well as the biocompatibility of the dialyser were independent determinants of AB-amyloidosis. CONCLUSION: It would be prudent clinical practice to employ high-flux biocompatible membranes in conjunction with ultrapure dialysis fluid for the treatment of end-stage renal disease patients who need to remain on long-term haemodialysis.

Hemophilic pseudotumor of the ulna treated with low dose radiation therapy: a case report. (5/147)We report a case of hemophilic pseudotumor in the ulna of a 6-year-old boy treated with radiation therapy. A total dose of 900 cGy in 6 fractions was given in 6 consecutive days. Progression of cystic changes was halted within a month. New bone formation and trabeculation were found on the 4th month. Complete healing of the lesion and bony replacement were found on the 12th month. The patient was followed up to 72 months and there was no evidence of recurrence and no bone growth disturbance. Radiation therapy can be an effective alternative modality in treating hemophilic pseudotumor. (+info)
Cannulation of simple bone cysts. (6/147)We describe a consecutive series of 26 patients with simple bone cysts who were treated by curettage, multiple drilling and continuous decompression by the insertion of either a cannulated screw or a pin. In the first 15 patients we used titanium cannulated screws (group 1) and in the next 11 a cannulated hydroxyapatite pin (group 2). Satisfactory healing was achieved in 12 patients in group 1 (80%) and in all in group 2. This technique seems to be a promising option for the treatment of simple bone cysts. The cannulated hydroxyapatite pin is recommended because of its higher success rate and the fact that it does not need to be removed. (+info)
Intertrochanteric osteotomy for osteoarthritis of the hip. A radiological assessment of non-compressive and compressive methods. (7/147)A radiological review of two groups of intertrochanteric osteotomies of the femur for primary osteoarthritis of the hip has been made. Each group oroginally consisted of forty-one hips. In one group a Wainwright straight V-spline without compression had been used for fixation, and in the other group an AO angled plate with compression. The time for bony union was equal in the two groups but the incidence of non-union was lower in the AO group. Regression of cysts and of bone sclerosis was more frequent in the Wainwright group, possible as a consequence of the greater medial displacement and varus angulation. (+info)
Unicameral bone cysts treated by injection of bone marrow or methylprednisolone. (8/147)In 79 consecutive patients with unicameral bone cysts we compared the results of aspiration and injection of bone marrow with those of aspiration and injection of steroid. All were treated by the same protocol. The only difference was the substance injected into the cysts. The mean radiological follow-up to detect activity in the cyst was 44 months (12 to 108). Of the 79 patients, 14 received a total of 27 injections of bone marrow and 65 a total of 99 injections of steroid. Repeated injections were required in 57% of patients after bone marrow had been used and in 49% after steroid. No complications were noted in either group. In this series no advantage could be shown for the use of autogenous injection of bone marrow compared with injection of steroid in the management of unicameral bone cysts. (+info)
There are several types of bone cysts, including:
1. Simple bone cysts: These are the most common type of bone cyst and typically occur in children and young adults. They are filled with air or fluid and do not contain any cancerous cells.
2. Angiomatous cysts: These are smaller than simple bone cysts and are usually found near the ends of long bones. They are also filled with blood vessels and do not contain any cancerous cells.
3. Unicameral (simple) bone cysts: These are similar to simple bone cysts but are larger and may be more complex in shape.
4. Multicameral bone cysts: These are larger than unicameral bone cysts and may contain multiple chambers filled with air or fluid.
5. Enchondromas: These are benign tumors that occur within the cartilage of a bone. They are usually found in the long bones of the arms and legs.
6. Chondromyxoid fibromas: These are rare, benign tumors that occur in the cartilage of a bone. They are typically found in the long bones of the arms and legs.
7. Osteochondromas: These are benign tumors that arise from the cartilage and bone of a joint. They are usually found near the ends of long bones.
8. Malignant bone cysts: These are rare and can be cancerous. They may occur in any bone of the body and can be aggressive, spreading quickly to other areas of the body.
The symptoms of bone cysts can vary depending on their size and location. They may cause pain, swelling, and limited mobility in the affected limb. In some cases, they may also lead to fractures or deformities.
Diagnosis of bone cysts usually involves imaging tests such as X-rays, CT scans, or MRI scans. A biopsy may also be performed to confirm the diagnosis and rule out other possible conditions.
Treatment for bone cysts depends on their size, location, and severity. Small, asymptomatic cysts may not require any treatment, while larger cysts may need to be drained or surgically removed. In some cases, medication such as bisphosphonates may be used to help reduce the risk of fractures.
In conclusion, bone cysts are abnormalities that can occur in any bone of the body. They can be benign or malignant and can cause a range of symptoms depending on their size and location. Diagnosis is usually made through imaging tests, and treatment may involve observation, draining, or surgical removal.
Surgery is often necessary to treat bone cysts, aneurysmal, and the type of surgery will depend on the size and location of the cyst. The goal of surgery is to remove the cyst and any associated damage to the bone. In some cases, the bone may need to be repaired or replaced with a prosthetic.
Bone cysts, aneurysmal are relatively rare and account for only about 1% of all bone tumors. They can occur in people of any age but are most commonly seen in children and young adults. Treatment is usually successful, but there is a risk of complications such as infection or nerve damage.
Bone cysts, aneurysmal are also known as bone aneurysmal cysts or BACs. They are different from other types of bone cysts, such as simple bone cysts or fibrous dysplasia, which have a different cause and may require different treatment.
Overall, the prognosis for bone cysts, aneurysmal is generally good if they are treated promptly and effectively. However, there is always a risk of complications, and ongoing follow-up with a healthcare provider is important to monitor for any signs of recurrence or further problems.
There are many different types of cysts that can occur in the body, including:
1. Sebaceous cysts: These are small, usually painless cysts that form in the skin, particularly on the face, neck, or torso. They are filled with a thick, cheesy material and can become inflamed or infected.
2. Ovarian cysts: These are fluid-filled sacs that form on the ovaries. They are common in women of childbearing age and can cause pelvic pain, bloating, and other symptoms.
3. Kidney cysts: These are fluid-filled sacs that form in the kidneys. They are usually benign but can cause problems if they become large or infected.
4. Dermoid cysts: These are small, usually painless cysts that form in the skin or organs. They are filled with skin cells, hair follicles, and other tissue and can become inflamed or infected.
5. Pilar cysts: These are small, usually painless cysts that form on the scalp. They are filled with a thick, cheesy material and can become inflamed or infected.
6. Epidermoid cysts: These are small, usually painless cysts that form just under the skin. They are filled with a thick, cheesy material and can become inflamed or infected.
7. Mucous cysts: These are small, usually painless cysts that form on the fingers or toes. They are filled with a clear, sticky fluid and can become inflamed or infected.
8. Baker's cyst: This is a fluid-filled cyst that forms behind the knee. It can cause swelling and pain in the knee and is more common in women than men.
9. Tarlov cysts: These are small, fluid-filled cysts that form in the spine. They can cause back pain and other symptoms, such as sciatica.
10. ganglion cysts: These are noncancerous lumps that form on the joints or tendons. They are filled with a thick, clear fluid and can cause pain, swelling, and limited mobility.
It's important to note that this is not an exhaustive list and there may be other types of cysts that are not included here. If you suspect that you have a cyst, it's always best to consult with a healthcare professional for proper diagnosis and treatment.
There are several types of jaw cysts that can develop, including:
1. Dermoid cysts: These cysts are made up of skin cells and are usually found in the temples of the jawbone.
2. Epidermoid cysts: These cysts are also made up of skin cells, but they are usually found on the underside of the tongue or in the floor of the mouth.
3. Mucocele: This type of cyst is made up of mucous membranes and is usually found in the lower jawbone.
4. Branchial cysts: These cysts are remnants of the second branchial arch, which normally disappears before birth. They are usually found on one side of the neck or jawbone.
5. Median mandibular cysts: These cysts are located in the middle of the lower jawbone and are typically small and round.
The exact cause of jaw cysts is not known, but they may be related to a blockage of the salivary glands or a developmental abnormality. Jaw cysts can be diagnosed using imaging tests such as X-rays, CT scans, and MRI scans. Treatment for jaw cysts usually involves surgical removal, but the type of treatment will depend on the size, location, and type of cyst. In some cases, observation may be recommended if the cyst is small and not causing any symptoms.
In summary, jaw cysts are non-cancerous growths that can develop in the tissues of the jawbone. There are several types of jaw cysts, and they can cause a range of symptoms from none to pain and difficulty opening the mouth. Treatment usually involves surgical removal, but the type of treatment will depend on the size, location, and type of cyst.
Some common types of mandibular diseases include:
1. Temporomandibular joint (TMJ) disorders: These are conditions that affect the joint that connects the mandible to the skull, causing pain and limited mobility in the jaw.
2. Osteomyelitis: This is a bone infection that can occur in the mandible, often as a result of trauma or infection.
3. Bone cancer: This is a malignant tumor that can develop in the mandible, often affecting the jawbone and surrounding tissues.
4. Osteogenic sarcoma: This is a type of bone cancer that typically occurs in the mandible of young adults.
5. Fibrous dysplasia: This is a developmental disorder where abnormal fibrous tissue develops in the mandible, leading to bone deformity and pain.
6. Non-odontogenic mandibular keratocyst: This is a benign cyst that can occur in the mandible, often causing pain and swelling.
7. Mandibular fracture: This is a break in the mandible that can be caused by trauma, such as a fall or a blow to the face.
8. Ameloblastoma: This is a rare benign tumor that develops in the mandible, often causing pain and swelling.
9. Pyogenic granuloma: This is a type of bacterial infection that can occur in the mandible, often causing pain and swelling.
10. Osteochondroma: This is a benign cartilage-capped bone tumor that can occur in the mandible, often causing pain and limited mobility in the jaw.
These are just a few examples of mandibular diseases, and there are many other conditions that can affect the mandible as well. If you are experiencing any symptoms or pain in your jaw, it is important to see a dentist or oral surgeon for proper diagnosis and treatment.
Types of Ovarian Cysts:
1. Functional cysts: These cysts form during the menstrual cycle and are usually small and disappear on their own within a few days or weeks.
2. Follicular cysts: These cysts form when a follicle (a tiny sac containing an egg) does not release an egg and instead fills with fluid.
3. Corpus luteum cysts: These cysts form when the corpus luteum (the sac that holds an egg after it's released from the ovary) does not dissolve after pregnancy or does not produce hormones properly.
4. Endometrioid cysts: These cysts are formed when endometrial tissue (tissue that lines the uterus) grows outside of the uterus and forms a cyst.
5. Cystadenomas: These cysts are benign tumors that grow on the surface of an ovary or inside an ovary. They can be filled with a clear liquid or a thick, sticky substance.
6. Dermoid cysts: These cysts are formed when cells from the skin or other organs grow inside an ovary. They can contain hair follicles, sweat glands, and other tissues.
Symptoms of Ovarian Cysts:
1. Pelvic pain or cramping
2. Bloating or discomfort in the abdomen
3. Heavy or irregular menstrual bleeding
4. Pain during sex
5. Frequent urination or difficulty emptying the bladder
6. Abnormal vaginal bleeding or spotting
Diagnosis and Treatment of Ovarian Cysts:
1. Pelvic examination: A doctor will check for any abnormalities in the reproductive organs.
2. Ultrasound: An ultrasound can help identify the presence of a cyst and determine its size, location, and composition.
3. Blood tests: Blood tests can be used to check hormone levels and rule out other conditions that may cause similar symptoms.
4. Laparoscopy: A laparoscope (a thin tube with a camera and light) is inserted through a small incision in the abdomen to visualize the ovaries and remove any cysts.
5. Surgical removal of cysts: Cysts can be removed by surgery, either through laparoscopy or open surgery.
6. Medications: Hormonal medications may be prescribed to shrink the cyst and alleviate symptoms.
It is important to note that not all ovarian cysts cause symptoms, and some may go away on their own without treatment. However, if you experience any of the symptoms mentioned above or have concerns about an ovarian cyst, it is essential to consult a healthcare provider for proper diagnosis and treatment.
The tumor usually appears as a well-defined lump or mass that is surrounded by a fibrous capsule. The surface of the tumor may be smooth or rough, and it may be covered with cartilage or bone. Chondroblastoma tends to grow slowly over time, but it can sometimes become malignant and invade surrounding tissues.
Chondroblastoma is most commonly found in young adults, typically between the ages of 20 and 40. The exact cause of chondroblastoma is not known, but it may be linked to genetic factors or environmental exposures. Treatment usually involves surgery to remove the tumor, followed by radiation therapy or chemotherapy to prevent recurrence.
Some of the common symptoms of Chondroblastoma include:
* Painless lump or mass in the affected limb
* Limited mobility and stiffness in the affected joint
* Swelling and redness in the affected area
* Warmth and tenderness to touch
Some of the common diagnostic tests for Chondroblastoma include:
* CT scans
* MRI scans
It's important to note that while chondroblastoma is a benign tumor, it can recur in some cases. Therefore, regular follow-up appointments with your doctor are essential to monitor the condition and detect any signs of recurrence early on.
Epidermal cysts are relatively common and can occur anywhere on the body, but they are most commonly found on the face, neck, torso, and arms. They are usually small, ranging in size from a pinpoint to a pea-sized bump, but they can sometimes grow larger.
Epidermal cysts are benign (non-cancerous) growths, and they typically do not cause any symptoms unless they become infected or rupture. In rare cases, epidermal cysts can become inflamed or infected, which can lead to redness, swelling, and pain.
Epidermal cysts are usually diagnosed by a dermatologist or other healthcare provider based on their appearance and location. In some cases, a biopsy may be performed to confirm the diagnosis. Treatment for epidermal cysts is usually not necessary unless they become inflamed or infected, in which case antibiotics or surgical drainage may be recommended.
It's important to note that epidermal cysts are different from sebaceous cysts, which are similar but occur in the deeper layers of the skin and are filled with a thick, cheesy material. Both types of cysts are benign and typically do not cause any symptoms unless they become infected or rupture.
Some common types of bone neoplasms include:
* Osteochondromas: These are benign tumors that grow on the surface of a bone.
* Giant cell tumors: These are benign tumors that can occur in any bone of the body.
* Chondromyxoid fibromas: These are rare, benign tumors that develop in the cartilage of a bone.
* Ewing's sarcoma: This is a malignant tumor that usually occurs in the long bones of the arms and legs.
* Multiple myeloma: This is a type of cancer that affects the plasma cells in the bone marrow.
Symptoms of bone neoplasms can include pain, swelling, or deformity of the affected bone, as well as weakness or fatigue. Treatment options depend on the type and location of the tumor, as well as the severity of the symptoms. Treatment may involve surgery, radiation therapy, chemotherapy, or a combination of these.
Some common types of spinal diseases include:
1. Degenerative disc disease: This is a condition where the discs between the vertebrae in the spine wear down over time, leading to pain and stiffness in the back.
2. Herniated discs: This occurs when the gel-like center of a disc bulges out through a tear in the outer layer, putting pressure on nearby nerves and causing pain.
3. Spinal stenosis: This is a narrowing of the spinal canal, which can put pressure on the spinal cord and nerve roots, causing pain, numbness, and weakness in the legs.
4. Spondylolisthesis: This is a condition where a vertebra slips out of place, either forward or backward, and can cause pressure on nearby nerves and muscles.
5. Scoliosis: This is a curvature of the spine that can be caused by a variety of factors, including genetics, injury, or disease.
6. Spinal infections: These are infections that can affect any part of the spine, including the discs, vertebrae, and soft tissues.
7. Spinal tumors: These are abnormal growths that can occur in the spine, either primary ( originating in the spine) or metastatic (originating elsewhere in the body).
8. Osteoporotic fractures: These are fractures that occur in the spine as a result of weakened bones due to osteoporosis.
9. Spinal cysts: These are fluid-filled sacs that can form in the spine, either as a result of injury or as a congenital condition.
10. Spinal degeneration: This is a general term for any type of wear and tear on the spine, such as arthritis or disc degeneration.
If you are experiencing any of these conditions, it is important to seek medical attention to receive an accurate diagnosis and appropriate treatment.
Maxillary diseases refer to any conditions or disorders that affect the maxilla, which is the bone that forms the upper jaw and holds the teeth in place. These diseases can cause a range of symptoms, including pain, swelling, and difficulty opening or closing the mouth. Some common maxillary diseases include:
1. Maxillary sinusitis: Inflammation of the air-filled cavities within the maxilla bone, often caused by infection or allergies.
2. Maxillary fracture: A break in the bone that can be caused by trauma, such as a fall or a blow to the face.
3. Cysts and tumors: Non-cancerous growths that can develop in the maxilla bone, often causing pain and swelling.
4. Dacryostenosis: A blockage of the tear ducts, which can cause tears to build up and overflow from the eyes.
5. Orbital cellulitis: Inflammation of the tissues around the eye, often caused by bacterial infection.
6. Subperiosteal abscess: An accumulation of pus beneath the periosteum, the thin layer of tissue that covers the surface of the bone.
7. Osteomyelitis: Infection of the bone and bone marrow, often caused by bacteria or other microorganisms.
8. Osteoma: A benign tumor made up of bone tissue, often found in the maxilla bone.
9. Pyogenic granuloma: A type of non-cancerous growth that develops in response to infection.
10. Fibrous dysplasia: A condition where abnormal development of fibrous tissue causes deformity and pain.
These maxillary diseases can be caused by a variety of factors, including infection, injury, genetics, and autoimmune disorders. Treatment options vary depending on the specific diagnosis and severity of the disease, but may include antibiotics, surgery, or other medications.
There are several factors that can contribute to bone resorption, including:
1. Hormonal changes: Hormones such as parathyroid hormone (PTH) and calcitonin can regulate bone resorption. Imbalances in these hormones can lead to excessive bone resorption.
2. Aging: As we age, our bones undergo remodeling more frequently, leading to increased bone resorption.
3. Nutrient deficiencies: Deficiencies in calcium, vitamin D, and other nutrients can impair bone health and lead to excessive bone resorption.
4. Inflammation: Chronic inflammation can increase bone resorption, leading to bone loss and weakening.
5. Genetics: Some genetic disorders can affect bone metabolism and lead to abnormal bone resorption.
6. Medications: Certain medications, such as glucocorticoids and anticonvulsants, can increase bone resorption.
7. Diseases: Conditions such as osteoporosis, Paget's disease of bone, and bone cancer can lead to abnormal bone resorption.
Bone resorption can be diagnosed through a range of tests, including:
1. Bone mineral density (BMD) testing: This test measures the density of bone in specific areas of the body. Low BMD can indicate bone loss and excessive bone resorption.
2. X-rays and imaging studies: These tests can help identify abnormal bone growth or other signs of bone resorption.
3. Blood tests: Blood tests can measure levels of certain hormones and nutrients that are involved in bone metabolism.
4. Bone biopsy: A bone biopsy can provide a direct view of the bone tissue and help diagnose conditions such as Paget's disease or bone cancer.
Treatment for bone resorption depends on the underlying cause and may include:
1. Medications: Bisphosphonates, hormone therapy, and other medications can help slow or stop bone resorption.
2. Diet and exercise: A healthy diet rich in calcium and vitamin D, along with regular exercise, can help maintain strong bones.
3. Physical therapy: In some cases, physical therapy may be recommended to improve bone strength and mobility.
4. Surgery: In severe cases of bone resorption, surgery may be necessary to repair or replace damaged bone tissue.
Some common types of bone diseases include:
1. Osteoporosis: A condition characterized by brittle, porous bones that are prone to fracture.
2. Osteoarthritis: A degenerative joint disease that causes pain and stiffness in the joints.
3. Rheumatoid arthritis: An autoimmune disorder that causes inflammation and pain in the joints.
4. Bone cancer: A malignant tumor that develops in the bones.
5. Paget's disease of bone: A condition characterized by abnormal bone growth and deformity.
6. Osteogenesis imperfecta: A genetic disorder that affects the formation of bone and can cause brittle bones and other skeletal deformities.
7. Fibrous dysplasia: A rare condition characterized by abnormal growth and development of bone tissue.
8. Multiple myeloma: A type of cancer that affects the plasma cells in the bone marrow.
9. Bone cysts: Fluid-filled cavities that can form in the bones and cause pain, weakness, and deformity.
10. Bone spurs: Abnormal growths of bone that can form along the edges of joints and cause pain and stiffness.
Bone diseases can be diagnosed through a variety of tests, including X-rays, CT scans, MRI scans, and bone biopsies. Treatment options vary depending on the specific disease and can include medication, surgery, or a combination of both.
The exact cause of FDB is unknown, but it is believed to be associated with genetic mutations, hormonal imbalances, and environmental factors. The condition typically affects individuals during childhood or adolescence, and the symptoms can vary in severity and progression.
Some common features of FDB include:
1. Painful bone deformities: FDB can cause bony outgrowths or deformities that are painful and can limit joint mobility.
2. Limited mobility: The deformities caused by FDB can lead to limited range of motion in the affected limbs, making it difficult to perform everyday activities.
3. Fractures: The abnormal bone tissue is prone to fracture, which can be painful and may require surgical intervention.
4. Difficulty with weight-bearing: The deformities and fractures caused by FDB can make it difficult for individuals to bear weight on the affected limbs, leading to difficulty walking or standing.
5. Cosmetic concerns: The bony deformities and outgrowths associated with FDB can cause cosmetic concerns for individuals, particularly during adolescence and young adulthood.
Treatment options for FDB vary depending on the severity of the condition and may include medications to manage pain and inflammation, surgery to correct bone deformities or remove affected tissue, and physical therapy to improve mobility and strength. In severe cases, FDB can lead to complications such as infection, nerve compression, and bone cancer, which require prompt medical attention.
Overall, fibrous dysplasia of bone is a rare and complex condition that can have significant impacts on an individual's quality of life and may require long-term management and treatment.
There are different types of mediastinal cysts, including:
1. Thymic cysts: These are usually benign and arise from abnormal development of the thymus gland.
2. Cystic hygromas: These are rare congenital tumors that are caused by the abnormal growth of the lymphatic system.
3. Lymphangioma: These are also rare, and are caused by the abnormal growth of lymphatic vessels.
4. Teratoma: These are very rare, and are caused by the abnormal growth of cells from all three germ layers (ectoderm, endoderm, and mesoderm).
Symptoms of mediastinal cysts can include chest pain, shortness of breath, coughing, and difficulty swallowing. These symptoms can vary depending on the size and location of the cyst.
Diagnosis of a mediastinal cyst is typically made through a combination of imaging studies such as chest X-rays, computed tomography (CT) scans, and magnetic resonance imaging (MRI) scans. A fine needle aspiration biopsy may also be performed to confirm the diagnosis.
Treatment of mediastinal cysts depends on the type and size of the cyst, as well as the symptoms it is causing. Small, asymptomatic cysts may not require treatment, while larger cysts that are causing symptoms may need to be surgically removed. In some cases, the cyst may be drained using a thoracentesis or chest tube.
Prognosis for patients with mediastinal cysts is generally good, especially if the cyst is benign and small in size. However, larger cysts that are not treated can lead to complications such as infection, respiratory problems, and compression of nearby structures. In rare cases, malignant mediastinal cysts may be present, which can have a poorer prognosis if left untreated.
Overall, mediastinal cysts are relatively rare and can cause a range of symptoms, from mild to severe. While most are benign, it is important to seek medical attention if symptoms persist or worsen over time, as timely diagnosis and treatment can improve outcomes for patients with these cysts.
The hallmark of GCTB is its large size, with tumors often measuring several centimeters in diameter. The tumor cells are giant cells, which are larger than normal osteoblasts, and they have a distinctive "salt and pepper" appearance under the microscope due to the mixture of light and dark-staining cytoplasmic granules.
The clinical presentation of GCTB varies depending on the location and size of the tumor. Large tumors can cause symptoms such as pain, swelling, and limited mobility in the affected limb. Smaller tumors may not cause any symptoms and may be incidentally discovered on imaging studies performed for other reasons.
GCTB is a slow-growing tumor, and the exact cause of its development is unknown. Genetic mutations have been identified in some cases, but the exact mechanisms underlying GCTB remain unclear. Treatment options for GCTB include surgery, radiation therapy, and chemotherapy, depending on the size and location of the tumor and the patient's overall health.
In conclusion, giant cell tumor of bone is a rare and benign bone tumor that can occur in any bone of the body. It is characterized by its large size and distinctive histopathological features. Treatment options vary depending on the size and location of the tumor and the patient's overall health.
Examples of spontaneous fractures include:
1. Pathological fractures: Fractures that occur in the presence of a bone-weakening condition such as osteoporosis, Paget's disease, or bone cancer.
2. Stress fractures: Small cracks in the bone that occur due to repetitive stress or overuse, often seen in athletes or individuals engaged in high-impact activities.
3. Osteogenesis imperfecta: A genetic disorder characterized by brittle bones and an increased risk of fractures.
4. Osteoporotic fractures: Fractures that occur due to bone loss and weakening associated with osteoporosis.
5. Frailty fractures: Fractures that occur in individuals who are frail or have a low bone mineral density, often seen in older adults.
Symptoms of spontaneous fractures may include pain, swelling, and difficulty moving the affected limb. Treatment for these fractures depends on the underlying cause and may involve immobilization, medication, or surgery.
Synovial cysts are usually benign, meaning they are not cancerous, but they can cause significant discomfort and disrupt daily activities. Treatment options for synovial cysts include draining the fluid from the cyst, physiotherapy to improve range of motion and strength, or surgery to remove the cyst if it is large and causing persistent symptoms.
The formation of a synovial cyst is often caused by trauma to the joint or tendon, such as a fall or repetitive strain injury. It can also be caused by conditions such as rheumatoid arthritis or osteoarthritis, which can lead to inflammation and fluid buildup in the joints. In some cases, synovial cysts may be inherited or may occur spontaneously without any known cause.
Synovial cysts are usually diagnosed through a combination of physical examination, imaging tests such as X-rays or ultrasound, and arthroscopy, which involves inserting a small camera into the joint to view the inside of the joint and detect any abnormalities.
It's important to seek medical attention if you experience persistent pain or swelling in a joint, as these symptoms could be indicative of a synovial cyst or another underlying condition that requires treatment. With proper diagnosis and treatment, it is possible to effectively manage the symptoms of a synovial cyst and improve joint function and mobility.
The term "bronchogenic" refers to the fact that these cysts arise from the bronchial tree, which is the network of airways that branch off from the trachea (windpipe) and lead to the lungs.
Bronchogenic cysts are typically located in the periphery of the lung, away from the center of the chest cavity. They can range in size from a few millimeters to several centimeters in diameter, and may be filled with air or fluid.
The exact cause of bronchogenic cysts is not known, but they are thought to result from abnormal development of the lung tissue during fetal life. They may be inherited in some cases, and there is a slightly higher risk of developing a bronchogenic cyst if there is a family history of the condition.
Bronchogenic cysts can cause a variety of symptoms, including:
* Chest pain
* Shortness of breath
In some cases, bronchogenic cysts may become infected or rupture, leading to more severe complications such as pneumonia or respiratory failure.
Diagnosis of a bronchogenic cyst typically involves a combination of chest X-rays, computed tomography (CT) scans, and magnetic resonance imaging (MRI) scans. A bronchogenic cyst is often visible on these imaging tests as a well-defined mass in the lung.
Treatment for a bronchogenic cyst usually involves surgical removal of the cyst, although in some cases, observation may be recommended if the cyst is small and not causing any symptoms. Surgery is typically performed through a small incision in the chest, and may involve the use of a thoracoscope (a flexible tube with a camera and light on the end) to visualize the cyst.
In addition to surgical removal, other treatments for bronchogenic cysts may include antibiotics if the cyst becomes infected, or pain management medication if the cyst is causing discomfort.
Overall, while a bronchogenic cyst can be a serious condition, with proper diagnosis and treatment, most people are able to recover fully and lead normal lives.
Mandibular Injuries can range from mild to severe and can affect different parts of the jaw bone, including the symphysis (the joint between the two halves of the mandible), the condyle (the rounded end of the mandible that articulates with the temporal bone of the skull), and the ramus (the outer portion of the mandible).
Some common types of Mandibular Injuries include:
1. Fractures: These are breaks in the bone that can be caused by direct trauma or a sudden impact.
2. Luxation injuries: These occur when the jaw bone becomes dislocated or moves out of its normal position.
3. Avulsions: These occur when a piece of bone is torn away from the rest of the mandible.
4. Subluxations: These occur when the jaw bone partially dislocates or slips out of place.
5. Contusions: These are bruises that occur when the mandible hits another object or surface.
6. Stretching and tearing of the soft tissue surrounding the mandible, such as muscles, ligaments, and tendons.
Symptoms of Mandibular Injuries can include pain, swelling, difficulty opening or closing the mouth, difficulty speaking or eating, and difficulty moving the jaw. Treatment for these injuries may involve immobilization of the mandible with a splint or cast, medication to manage pain and inflammation, and in some cases surgery to realign or repair the bone.
Dermoid cysts are usually benign, meaning they are not cancerous, and they do not spread to other parts of the body. However, they can cause a variety of symptoms, such as pain, swelling, and discomfort, depending on their size and location. In some cases, dermoid cysts may become infected or rupture, leading to further complications.
Dermoid cysts are relatively rare, and they can affect anyone, but they are more common in women than men. They are often diagnosed through imaging tests such as ultrasound or MRI, and they may be treated with surgical removal if they are causing symptoms or are suspected to be cancerous.
In summary, dermoid cysts are non-cancerous growths that can develop on or just under the skin in various parts of the body, and they can cause a range of symptoms. They are relatively rare and can be diagnosed through imaging tests, and they may be treated with surgical removal if necessary.
Nonodontogenic cysts are a type of cyst that does not arise from the dental follicle or the odontogenic tissues. They are typically benign and can occur in various parts of the body, but are more common in the head and neck region. These cysts are usually slow-growing and may not cause any symptoms until they become large enough to compress adjacent structures or cause damage to surrounding tissues.
Examples of nonodontogenic cysts include:
1. Epidermoid cysts: These are the most common type of nonodontogenic cyst and are formed from skin cells that have accumulated in a ball-like structure. They can occur anywhere on the body, but are most commonly found on the face, neck, or scalp.
2. Pilar cysts: These are small, fluid-filled cysts that form on the scalp and are often inherited.
3. Eruptive cysts: These are small, noncancerous cysts that can occur anywhere on the body but are most commonly found on the face and neck.
4. Dermoid cysts: These are benign growths that are formed from skin cells and can occur anywhere on the body.
5. Cystic hygromas: These are rare, noncancerous growths that form in the neck or throat area.
Treatment for nonodontogenic cysts usually involves surgical excision, and the prognosis is generally good if the cyst is removed completely. However, if the cyst is not removed, it can continue to grow and cause further complications, such as infection or compression of adjacent structures.
Open fracture: The bone breaks through the skin, exposing the bone to the outside environment.
Closed fracture: The bone breaks, but does not penetrate the skin.
Comminuted fracture: The bone is broken into many pieces.
Hairline fracture: A thin crack in the bone that does not fully break it.
Non-displaced fracture: The bone is broken, but remains in its normal position.
Displaced fracture: The bone is broken and out of its normal position.
Stress fracture: A small crack in the bone caused by repetitive stress or overuse.
The exact cause of cementoma is not well understood, but it is believed to be related to chronic inflammation or trauma to the jawbone. It typically affects adults between the ages of 20 and 60 years old, with a slight predilection for men. The symptoms of cementoma can vary depending on the size and location of the tumor, but may include painless swelling or lump in the jaw, tooth mobility, and difficulty opening the mouth.
The diagnosis of cementoma is based on a combination of clinical examination, radiographic findings (such as X-rays and CT scans), and histopathological analysis of a biopsy sample. Treatment for cementoma usually involves surgical removal of the tumor, and in some cases, may be followed by radiation therapy to ensure complete eradication of the tumor. The prognosis for cementoma is generally good, and the tumor has a low risk of recurrence after surgical excision. However, long-term follow-up is necessary to monitor for any signs of recurrence or new tumors.
In summary, cementoma is a rare benign tumor that develops in the jawbone, usually in the mandible (lower jawbone). It is a slow-growing mass composed of cementum and can cause symptoms such as painless swelling or lump in the jaw, tooth mobility, and difficulty opening the mouth. The diagnosis is based on a combination of clinical examination, radiographic findings, and histopathological analysis of a biopsy sample, and treatment usually involves surgical removal of the tumor followed by radiation therapy if necessary. The prognosis for cementoma is generally good, but long-term follow-up is necessary to monitor for any signs of recurrence or new tumors.
Some common types of orbital diseases include:
1. Orbital cellulitis: This is an infection of the tissues in the orbit that can be caused by bacteria or viruses. It can cause swelling, redness, and pain in the eye and eyelid.
2. Orbital abscess: This is a collection of pus in the orbit that can be caused by an infection. It can cause swelling, redness, and pain in the eye and eyelid.
3. Dacryostenosis: This is a blockage of the tear ducts that can cause tears to build up in the eye and eyelid.
4. Orbital pseudotumor: This is a condition in which there is inflammation in the orbit without any obvious cause. It can cause pain, swelling, and double vision.
5. Thyroid eye disease: This is a condition that affects the muscles and tissues around the eyes due to an overactive thyroid gland. It can cause double vision, puffy eyelids, and dryness in the eyes.
6. Graves' ophthalmopathy: This is a condition that affects the muscles and tissues around the eyes due to an autoimmune disorder. It can cause double vision, puffy eyelids, and dryness in the eyes.
7. Orbital lymphoid hyperplasia: This is a condition in which there is an abnormal growth of immune cells in the orbit. It can cause pain, swelling, and redness in the eye and eyelid.
8. Orbital sarcoidosis: This is a condition in which there are inflammatory lesions in the orbit due to a systemic autoimmune disorder called sarcoidosis. It can cause pain, swelling, and redness in the eye and eyelid.
9. Orbital pseudotumor: This is a condition that mimics a tumor but is actually caused by inflammation or abnormal blood vessels in the orbit. It can cause pain, swelling, and double vision.
10. Orbital metastasis: This is a condition in which cancer cells from another part of the body spread to the orbit. It can cause pain, swelling, and redness in the eye and eyelid.
It's important to note that this is not an exhaustive list and there may be other causes of orbital inflammation. If you are experiencing symptoms of orbital inflammation, it's important to see an eye doctor or a specialist as soon as possible for proper evaluation and treatment.
There are several types of odontogenic cysts, including:
1. Dentigerous cyst: This is the most common type of odontogenic cyst and is formed from the remains of the dental lamina, which is the tissue that forms the teeth.
2. Gingivo-squamous cyst: This type of cyst is formed from the epithelial tissue that covers the roots of the teeth.
3. Lateral periodontal cyst: This type of cyst is formed in the periodontal ligament, which connects the teeth to the jawbone.
4. Periapical cyst: This type of cyst forms in the tissue surrounding the apex (tip) of the root of a tooth.
5. Radicular cyst: This type of cyst is formed from the epithelial tissue that lines the inside of the root canal.
Odontogenic cysts are usually diagnosed through radiographic examination, such as an X-ray or CT scan. Treatment depends on the size and location of the cyst, but may include observation, surgical enucleation (removal of the cyst), or apicoectomy (removal of the apex of the tooth).
Odontogenic cysts are benign and usually do not spread to other parts of the body. However, if left untreated, they can cause complications such as infection, pain, and damage to the surrounding bone and teeth.
The exact cause of radicular cysts is not well understood, but they are thought to arise from the chronic inflammation of the periodontal membrane due to local factors such as dental trauma or poor oral hygiene. The cysts typically develop near the apex of an affected tooth and can cause symptoms such as pain, swelling, and difficulty opening the mouth.
Radicular cysts are diagnosed through a combination of clinical examination, radiographic imaging, and histopathological analysis of a biopsy sample. Treatment options for radicular cysts depend on the size and location of the cyst, as well as the underlying cause. Small cysts may be monitored with regular dental check-ups, while larger cysts may require surgical removal.
In summary, a radicular cyst is a rare, non-odontogenic cyst that forms near the roots of teeth and can cause symptoms such as pain and swelling. The exact cause is not well understood, but chronic inflammation of the periodontal membrane is thought to be a contributing factor. Treatment options range from monitoring to surgical removal depending on the size and location of the cyst.
The exact cause of giant cell tumors is not known, but they are thought to arise from abnormalities in the mesenchymal cells that produce bone tissue. The tumors typically grow slowly and may remain asymptomatic for years before causing any symptoms. When symptoms do occur, they can include pain, swelling, and limited mobility in the affected limb.
Giant cell tumors are typically diagnosed through a combination of imaging studies such as X-rays, CT scans, and MRI scans, and a biopsy to confirm the presence of malignant cells. Treatment options for giant cell tumors include:
1. Surgery: The primary treatment for giant cell tumors is surgical excision, which involves removing the tumor and any affected surrounding bone tissue.
2. Radiation therapy: This may be used in combination with surgery or as a standalone treatment for patients who are not candidates for surgery.
3. Chemotherapy: This is rarely used to treat giant cell tumors, but may be considered in cases where the tumor has spread to other parts of the body.
4. Observation: In some cases, giant cell tumors may be monitored with regular imaging studies and biopsies to ensure that they do not grow or change over time.
Overall, giant cell tumors are benign bone tumors that can cause significant morbidity if left untreated. Early detection and treatment are essential to prevent long-term complications and improve outcomes for patients affected by these tumors.
The cyst forms when the dental follicle, which is the sac-like structure surrounding the developing tooth, becomes filled with fluid instead of the usual connective tissue. The cyst may be small or large, and can cause pressure on the surrounding bone and soft tissue, leading to symptoms such as:
* Pain in the affected tooth and gum
* Swelling of the face, neck, or jaw
* Difficulty opening the mouth or swallowing
* Redness and tenderness of the overlying skin
Dentigerous cysts are usually asymptomatic and are often detected during a routine dental exam. Treatment options include:
* Observation: Small, non-painful cysts may not require any treatment and can be monitored with regular check-ups.
* Drainage: Larger cysts may need to be drained surgically to relieve pressure and pain.
* Enucleation: The entire cyst may be removed if it is causing symptoms or if it is large and pressing on surrounding structures.
* Tooth extraction: If the cyst is associated with an impacted tooth, the tooth may need to be extracted.
It's important to note that dentigerous cysts are not cancerous and are usually benign. However, they should be monitored regularly by a dentist or oral surgeon to ensure that they do not grow and cause further complications.
* Osteogenesis imperfecta (OI): A genetic disorder that affects the formation of bone tissue, leading to fragile bones and an increased risk of fractures.
* Rickets: A vitamin D-deficient disease that causes softening of the bones in children.
* Osteomalacia: A condition similar to rickets, but affecting adults and caused by a deficiency of vitamin D or calcium.
* Hyperparathyroidism: A condition in which the parathyroid glands produce too much parathyroid hormone (PTH), leading to an imbalance in bone metabolism and an increase in bone resorption.
* Hypoparathyroidism: A condition in which the parathyroid glands produce too little PTH, leading to low levels of calcium and vitamin D and an increased risk of osteoporosis.
Bone diseases, metabolic are typically diagnosed through a combination of physical examination, imaging studies such as X-rays or CT scans, and laboratory tests to evaluate bone metabolism. Treatment depends on the specific underlying cause of the disease and may include medications, dietary changes, or surgery.
The symptoms of a mesenteric cyst can vary depending on its size and location, but may include:
* Abdominal pain or discomfort
* Abdominal swelling or distension
* Diarrhea or constipation
* Nausea and vomiting
If the cyst becomes infected or ruptures, it can lead to more severe symptoms such as:
* Severe abdominal pain
* Loss of appetite
* Abdominal tenderness and guarding (muscle tension)
The exact cause of mesenteric cysts is not known, but they are thought to be congenital (present at birth) or may develop as a result of an injury or inflammation.
Diagnosis of a mesenteric cyst typically involves imaging tests such as ultrasound, CT scan or MRI, which can help to identify the location and size of the cyst. A laparoscopy (a minimally invasive surgical procedure) may also be performed to confirm the diagnosis and to drain any fluid from the cyst.
Treatment for a mesenteric cyst usually involves draining the fluid from the cyst and removing any infected tissue. In some cases, the entire cyst may be removed if it is large or causing symptoms. Surgery is usually recommended to treat symptomatic cysts and to prevent complications such as infection or rupture.
Prognosis for mesenteric cysts is generally good if they are treated promptly and properly. However, if left untreated, they can lead to serious complications such as abscesses, sepsis, and potentially life-threatening infections.
Granulomas are formed when the immune system tries to wall off foreign substances or infections, and they can be a sign of chronic inflammation. In some cases, giant cell granulomas can be associated with certain autoimmune disorders, such as rheumatoid arthritis or sarcoidosis.
Giant cell granulomas are usually small and may not cause any symptoms unless they grow large enough to press on surrounding tissues or organs. However, they can sometimes cause pain, swelling, or other symptoms depending on their location.
If a giant cell granuloma is suspected, a healthcare provider may perform a biopsy to confirm the diagnosis. Treatment options for giant cell granulomas depend on the underlying cause and the severity of the condition. In some cases, treatment may involve medications to reduce inflammation or surgery to remove the affected tissue.
Tarlov cysts are named after the doctor who first described them, Joseph Tarlov. They're relatively rare, and doctors don't fully understand what causes them. They may be hereditary or related to spinal injuries or degenerative conditions such as osteoporosis.
Tarlov cysts usually are diagnosed with imaging tests such as MRI or CT scans. Treatment is rare and often focuses on pain management with medications, physical therapy, and other nonsurgical measures. In some cases, surgery may be necessary to drain the cyst or remove it altogether.
