Osteotomy of the tibia for correction of complex deformity. (1/220)

Twenty complex tibial deformities due to anterior poliomyelitis in 18 patients were corrected by a modified O'Donoghue osteotomy. This technique allowed correction of the deformity in three planes. This was achieved by widening the rectangular window distally to correct both rotation and valgus and by trimming the anterior edges of the step cuts to correct flexion deformity. An above-knee cast was applied for eight to 13 weeks and the patients followed up for a mean of 3.2 years. One of the 18 patients developed delayed union because of fracture of the medial limb of the step cut. The results showed excellent correction of the three-plane deformity and there was no recurrence. This method of osteotomy is a safe and simple procedure which does not require internal fixation and allows correction of torsional and angular deformity.  (+info)

The mechanism of the effect of obesity in knee osteoarthritis: the mediating role of malalignment. (2/220)

OBJECTIVE: Obesity is most strongly linked to osteoarthritis (OA) at the knee. Varus malalignment was examined as a possible local mediator that may increase the impact of body weight at the knee, versus the hip or ankle. Compartment load distribution is more equitable in valgus than in varus knees, and valgus knees may better tolerate obesity. We therefore tested whether 1) body mass index (BMI) is correlated with OA severity in varus knees, 2) the BMI-OA severity correlation is weaker in valgus than in varus knees, 3) BMI is correlated with the severity of varus malalignment, and 4) the BMI-medial tibiofemoral OA severity relationship is reduced after controlling for varus malalignment. METHODS: In 300 community-recruited patients with knee OA, 2 groups (varus and valgus) were identified based on dominant knee alignment on a full-limb radiograph, i.e., the angle formed by the intersection of the femoral and tibial mechanical axes. Severity of knee OA was assessed by measurement of the narrowest joint space width on radiographs of knees in a fluoroscopy-confirmed semiflexed position. RESULTS: Alignment direction was symmetric (or neutral in 1 limb) in 87% of patients. One hundred fifty-four patients had varus knees and 115 had valgus knees. BMI correlated with OA severity in the varus group (r = -0.29, P = 0.0009) but not in the valgus group (r = -0.13, P = 0.17). BMI correlated with malalignment in those with varus knees (r = 0.26) but not in those with valgus knees (r = 0.16). The partial correlation of BMI and OA severity, controlling for sex, was reduced from 0.24 (P = 0.002) to 0.04 (P = 0.42) when varus malalignment was added to the model. CONCLUSION: BMI was related to OA severity in those with varus knees but not in those with valgus knees. Much of the effect of BMI on the severity of medial tibiofemoral OA was explained by varus malalignment, after controlling for sex. Whether it precedes or follows the onset of disease, varus malalignment is one local factor that may contribute to rendering the knee most vulnerable to the effects of obesity.  (+info)

Open-wedge osteotomy by hemicallotasis or the closed-wedge technique for osteoarthritis of the knee. A randomised study of 50 operations. (3/220)

We describe the results of 50 operations carried out on 46 patients with medial osteoarthritis of the knee of Ahlback grade 1 to 3. Patients were randomised either to a closed-wedge high tibial osteotomy (HTO) or an open-wedge procedure based on the hemicallotasis technique (HCO). Their median age was 55 years (38 to 68). The preoperative median hip-knee-ankle (HKA) angle was 171 degrees (164 to 176) in the HTO group and 173 degrees (165 to 179) in the HCO group. After six weeks, the median HKA angle was 185 degrees (176 to 194) in the HTO group and 184 degrees (181 to 188) in the HCO group. In the HTO group, seven patients were within the range of 182 degrees to 186 degrees compared with 21 in the HCO group (p < 0.001). One year later, ten HTO patients were within this range while the HKA angulation in the HCO group was unchanged. At two years the numbers were 11 and 18, respectively. We evaluated the clinical results on the Hospital for Special Surgery, Lysholm and Wallgren-Tegner activity scores, and patients completed part of the Nottingham Health Profile questionnaire. An impartial observer at the two-year follow-up concluded that all scores had improved, but found no clinical differences between the groups.  (+info)

Hemicallotasis open-wedge osteotomy for osteoarthritis of the knee. Complications in 308 operations. (4/220)

We studied the complications after open-wedge osteotomy by hemicallotasis in 308 consecutive patients, most of whom had osteoarthritis of the knee. The participating surgeons, who worked at 17 hospitals, used their discretion in selecting patients, operating techniques and external fixators. The general complications included 11 cases of deep-vein thrombosis (4%), six of nonunion (2%) and one of septic arthritis of the knee. There were technical complications in 13 patients (4%). In 157 patients (51%) pin-site infections were recorded; of these, 96% were minor and responded to wound toilet and antibiotic treatment. A total of 18 revision procedures was carried out.  (+info)

The sulcus angle and malalignment of the extensor mechanism of the knee. (5/220)

Anterior knee pain due to dysplasia of the extensor mechanism is common. We have studied 137 knees (103 patients) in order to identify a rapid and reproducible radiological feature which would indicate the need for further analysis. Overall, 67 knees (49%) had at least one radiological abnormality; 70 (51%) were considered normal. There were five cases of Dejour type-3 dysplasia of the femoral trochlea, nine of type-2 and 12 of type-1. There were 49 cases of patella alta and five of patella infera. Four knees had an abnormal lateral patellofemoral angle (patellar tilt), and in 15 knees there was more than one abnormality. Classification of trochlear dysplasia was difficult and showed poor reproducibility. This was also true for the measurement of the lateral patellofemoral angle. Patellar height was more easily measured but took time. The sulcus angle is an easily and rapidly measurable feature which was reproducible and was closely related to other features of dysplasia of the extensor mechanism. The finding of a normal sulcus angle suggested that seeking other radiological evidence of malalignment of the extensor mechanism was unlikely to reveal additional useful information. The severity of other features of dysplasia of the extensor mechanism correlated with increasing sulcus angle.  (+info)

MRI study of talonavicular alignment in club foot. (6/220)

We studied in vivo the talonavicular alignment of club foot in infants using MRI. We examined 26 patients (36 feet) with congenital club foot. The mean age at examination was 9.0 months (4 to 12). All analyses used MRI of the earliest cartilaginous development of the tarsal bones in the transverse plane, rather than the ossific nucleus. The difference in the mean talar neck angle (44.0 +/- 8.1 degrees) in club foot was statistically significant (p < 0.001) when compared with that of the normal foot (30.8 +/- 5.5 degrees). The difference between the mean angles in the group treated by operation (47.9 +/- 6.7 degrees) and those treated conservatively (40.1 +/- 7.5 degrees) was also statistically significant. The anatomical relationship between the head of the talus and the navicular was divided into two patterns, based on the position of the mid-point of the navicular related to the long axis of the head. In the operative group, 18 feet were classified as having a medial shift of the navicular and none had a lateral shift. In the conservative group, 12 showed a medial shift of the navicular and six a lateral shift. All nine unaffected normal feet in which satisfactory MRI measurements were made showed a lateral shift of the navicular. Club feet had a larger talar neck angle and a more medially deviated navicular when compared with normal feet. This was more marked in the surgical group than in the conservative group.  (+info)

Computerised measurement of tibiofemoral alignment. (7/220)

Tibiofemoral alignment has a direct correlation with the survival of total knee arthroplasty. Traditionally, it has been measured using a goniometer on radiographs. We describe new software which measures this alignment on scanned radiographs by automatically detecting bones in the image. Two surgeons used conventional methods and two clerical officers used the computerised routine to assess 58 radiographs of the knee on two occasions. There were no significant differences between any of the paired comparisons. The largest mean difference detected was 1.19 degrees. Across all comparisons, the mean correlation was 0.755. A standardised routine for measuring tibiofemoral alignment was the greatest factor in reducing error in our study. These results show that non-medical staff can reliably use the software to measure tibiofemoral alignment. It has the potential to measure all the parameters recommended by the Knee Society.  (+info)

Fracture of the proximal tibia six months after Fulkerson osteotomy. A report of two cases. (8/220)

The Fulkerson osteotomy has proved to be a reliable treatment for subluxation of the patella due to malalignment. Aggressive rehabilitation in the early postoperative period is unwise since the proximal tibia is weakened by the oblique osteotomy. Early weight-bearing and unrestricted activity have caused fractures in a few patients. Even late in the postoperative period the osteotomy may adversely influence the biomechanical properties of the proximal tibia. We describe two athletes who sustained a fracture of the proximal tibia, during recreational activities, six months after a Fulkerson osteotomy. Both had been bearing full weight for about ten weeks without complaint. Bony healing of the osteotomy had been demonstrated on plain radiographs at ten and at 12 weeks. After a Fulkerson osteotomy, jogging and activities which impose considerable impact force should be discouraged for at least nine to 12 months.  (+info)

Bone malalignment refers to a condition where the bones in the body are not aligned properly, resulting in an abnormal position or orientation of the bones. This can occur due to a variety of factors, including injury, genetic factors, or developmental abnormalities. In the medical field, bone malalignment can be a serious condition that can lead to pain, limited mobility, and other complications. It can affect any part of the body, including the spine, hips, knees, and feet. Treatment for bone malalignment depends on the severity of the condition and the underlying cause. In some cases, conservative treatments such as physical therapy, braces, or orthotics may be sufficient to correct the alignment. In more severe cases, surgery may be necessary to realign the bones and restore proper function.

In the medical field, "bone and bones" typically refers to the skeletal system, which is made up of bones, cartilage, ligaments, tendons, and other connective tissues. The skeletal system provides support and structure to the body, protects vital organs, and allows for movement through the use of muscles. Bones are the main component of the skeletal system and are responsible for providing support and protection to the body. There are 206 bones in the human body, which are classified into four types: long bones, short bones, flat bones, and irregular bones. Long bones, such as the femur and humerus, are cylindrical in shape and are found in the arms and legs. Short bones, such as the carpals and tarsals, are cube-shaped and are found in the wrists and ankles. Flat bones, such as the skull and ribs, are thin and flat and provide protection to vital organs. Irregular bones, such as the vertebrae and pelvis, have complex shapes that allow for specific functions. Overall, the bone and bones of the skeletal system play a crucial role in maintaining the health and function of the human body.

Coxa vara is a medical condition in which the hip joint is abnormally turned inward, causing the thigh bone (femur) to angle inward as well. This can result in a characteristic bowing of the legs, with the inner thigh muscles becoming tight and the outer thigh muscles becoming weak. Coxavara can be caused by a variety of factors, including birth defects, developmental issues, or injuries to the hip joint. Treatment for coxavara may include physical therapy, bracing, or surgery, depending on the severity of the condition and the underlying cause.

Bone remodeling is a continuous process that occurs in the human body to maintain the strength and integrity of bones. It involves the coordinated activity of bone-forming cells called osteoblasts and bone-resorbing cells called osteoclasts. During bone remodeling, osteoclasts break down old or damaged bone tissue, releasing minerals and other components into the bloodstream. Osteoblasts then lay down new bone tissue to replace the old bone that was removed. This process of bone resorption followed by bone formation is a dynamic equilibrium that helps to maintain the balance between bone strength and bone density. Bone remodeling is influenced by a variety of factors, including hormones, mechanical stress, and age. For example, during childhood and adolescence, bone remodeling is stimulated by growth hormones and physical activity, leading to increased bone density and strength. In older adults, bone remodeling slows down, leading to a decrease in bone density and an increased risk of fractures. Disruptions in the bone remodeling process can lead to a variety of bone disorders, including osteoporosis, osteogenesis imperfecta, and Paget's disease. Understanding the mechanisms of bone remodeling is important for developing effective treatments for these conditions.

Osteoarthritis, also known as degenerative joint disease, is a common condition that affects the knee joint. It is a type of arthritis that occurs when the cartilage that cushions the ends of bones in the joint breaks down, leading to inflammation, pain, and stiffness. Over time, the bones may rub against each other, causing damage to the joint and reducing its ability to move freely. Osteoarthritis of the knee is a common cause of knee pain and disability, particularly in older adults. It can affect one or both knees and can be caused by a variety of factors, including age, injury, and genetics. Treatment options for osteoarthritis of the knee may include medications, physical therapy, and in severe cases, surgery.

Bone density is a measure of the amount of bone mineral content (BMC) in a specific area of the body, usually expressed in grams per cubic centimeter (g/cm³). It is an important indicator of bone health and strength, and is commonly used to diagnose and monitor osteoporosis, a condition characterized by low bone density and increased risk of fractures. Bone density is typically measured using dual-energy X-ray absorptiometry (DXA), which involves passing two low-energy X-ray beams through the body and measuring the amount of X-ray energy absorbed by the bones. The difference in the amount of energy absorbed by the bones at different energies is used to calculate bone density. Normal bone density is considered to be within a certain range, and bone density measurements below this range are considered to be low or osteoporotic. Low bone density is a risk factor for fractures, particularly of the spine, hip, and wrist. Treatment for low bone density may include lifestyle changes, such as regular exercise and a healthy diet, as well as medications to increase bone density or prevent further bone loss.

Bone resorption is a process in which bone tissue is broken down and removed by osteoclasts, which are specialized cells in the bone marrow. This process is a normal part of bone remodeling, which is the continuous process of bone formation and resorption that occurs throughout life. Bone resorption is necessary for the growth and development of bones, as well as for the repair of damaged bone tissue. However, excessive bone resorption can lead to a number of medical conditions, including osteoporosis, which is a condition characterized by weak and brittle bones that are prone to fractures. Other conditions that can be caused by excessive bone resorption include Paget's disease of bone, which is a disorder that causes the bones to become abnormally thick and weak, and hyperparathyroidism, which is a condition in which the parathyroid glands produce too much parathyroid hormone, which can lead to increased bone resorption. Bone resorption can also be caused by certain medications, such as corticosteroids, and by certain medical conditions, such as cancer and rheumatoid arthritis. In these cases, bone resorption can lead to a loss of bone mass and density, which can increase the risk of fractures and other complications.

Hallux varus is a medical condition in which the big toe (hallux) is bent inward at the joint, causing the toe to point towards the other toes. This condition is also known as "bunionette" or "tailor's bunion" when it affects the little toe. Hallux varus can be caused by a variety of factors, including genetics, foot structure, and footwear that does not fit properly. It can also be a result of an injury or arthritis. Symptoms of hallux varus may include pain, swelling, and difficulty walking or wearing certain types of shoes. Treatment options for hallux varus may include wearing orthotics, physical therapy, or surgery in severe cases.

Bone marrow is a soft, spongy tissue found inside the bones of most mammals, including humans. It is responsible for producing blood cells, including red blood cells, white blood cells, and platelets. Red blood cells are responsible for carrying oxygen throughout the body, white blood cells help fight infections and diseases, and platelets are involved in blood clotting. The bone marrow is divided into two main types: red bone marrow and yellow bone marrow. Red bone marrow is responsible for producing all types of blood cells, while yellow bone marrow is primarily responsible for producing fat cells. In some cases, the bone marrow can be damaged or diseased, leading to conditions such as leukemia, lymphoma, or aplastic anemia. In these cases, bone marrow transplantation may be necessary to replace damaged or diseased bone marrow with healthy bone marrow from a donor.

In the medical field, braces refer to a type of orthodontic device used to correct misaligned teeth and jaws. Braces are typically made of metal or ceramic brackets that are attached to the teeth and connected by wires. The wires are used to apply pressure to the teeth, gradually moving them into the correct position over time. Braces can be used to treat a variety of dental problems, including overbite, underbite, crowded teeth, and crooked teeth. They are usually worn for a period of several years, during which time the patient will need to visit their orthodontist regularly for adjustments.

Patellar dislocation is a medical condition in which the kneecap (patella) is forced out of its normal position and moves out of the groove (trochlear groove) in the femur bone. This can happen due to a direct blow to the knee, a fall onto the knee, or repetitive stress on the knee. The patella is a small, triangular bone that sits at the front of the knee joint. It helps to protect the knee joint and allows for smooth movement of the leg. When the patella is dislocated, it can cause pain, swelling, and difficulty moving the knee. Treatment for patellar dislocation typically involves physical therapy to strengthen the muscles around the knee and improve flexibility. In some cases, surgery may be necessary to realign the patella and stabilize the knee joint. It is important to seek medical attention if you suspect you have a patellar dislocation, as leaving it untreated can lead to long-term complications.

Bone neoplasms are abnormal growths or tumors that develop in the bones. They can be either benign (non-cancerous) or malignant (cancerous). Benign bone neoplasms are usually slow-growing and do not spread to other parts of the body, while malignant bone neoplasms can be invasive and spread to other parts of the body through the bloodstream or lymphatic system. There are several types of bone neoplasms, including osteosarcoma, Ewing's sarcoma, chondrosarcoma, and multiple myeloma. These tumors can affect any bone in the body, but they are most commonly found in the long bones of the arms and legs, such as the femur and tibia. Symptoms of bone neoplasms may include pain, swelling, and tenderness in the affected bone, as well as bone fractures that do not heal properly. Diagnosis typically involves imaging tests such as X-rays, MRI scans, and CT scans, as well as a biopsy to examine a sample of the tumor tissue. Treatment for bone neoplasms depends on the type and stage of the tumor, as well as the patient's overall health. Options may include surgery to remove the tumor, radiation therapy to kill cancer cells, chemotherapy to shrink the tumor, and targeted therapy to block the growth of cancer cells. In some cases, a combination of these treatments may be used.

Bone development, also known as osteogenesis, is the process by which bones grow and mature. It involves the differentiation of mesenchymal stem cells into osteoblasts, which are specialized cells that produce bone matrix. The bone matrix is a composite of collagen fibers and minerals, including calcium and phosphate, that give bones their strength and rigidity. During bone development, osteoblasts secrete bone matrix, which is then mineralized with calcium and phosphate. As the bone matrix mineralizes, osteoblasts differentiate into osteocytes, which are mature bone cells that are embedded within the bone matrix. Osteocytes are responsible for maintaining bone health by regulating bone resorption and formation. Bone development occurs throughout life, with the highest rates of bone growth occurring during childhood and adolescence. However, bone development is not complete until the early 20s, and bone continues to be remodeled and strengthened throughout life through a process called bone remodeling. Disruptions in bone development can lead to a variety of bone disorders, including osteogenesis imperfecta, which is a genetic disorder characterized by brittle bones, and rickets, which is a vitamin D deficiency that can lead to soft and weak bones.

Bone marrow cells are the cells found in the bone marrow, which is the soft, spongy tissue found in the center of bones. These cells are responsible for producing blood cells, including red blood cells, white blood cells, and platelets. There are two types of bone marrow cells: hematopoietic stem cells and progenitor cells. Hematopoietic stem cells are capable of dividing and differentiating into any type of blood cell, while progenitor cells are capable of dividing and differentiating into specific types of blood cells. In the medical field, bone marrow cells are often used in the treatment of blood disorders, such as leukemia and lymphoma, as well as in the transplantation of bone marrow to replace damaged or diseased bone marrow. In some cases, bone marrow cells may also be used in research to study the development and function of blood cells.

Foot deformities refer to any abnormality or deviation from the normal structure or function of the foot. These deformities can be caused by a variety of factors, including genetics, injury, disease, or poor footwear. Foot deformities can range from mild to severe and can affect the shape, alignment, or movement of the foot. Some common examples of foot deformities include bunions, hammertoes, flat feet, high arches, and plantar fasciitis. Treatment for foot deformities may include conservative measures such as orthotics, physical therapy, or shoe modifications, or surgical intervention in severe cases.

Bone transplantation is a surgical procedure in which a piece of healthy bone is taken from one part of the body and transplanted to another part of the body where there is a deficiency or damage to the bone. The transplanted bone can be used to replace a missing bone, to repair a broken bone, or to stabilize a bone that is at risk of breaking. There are several types of bone transplantation, including autografts, allografts, and synthetic bone grafts. Autografts involve taking bone from one part of the body and transplanting it to another part of the body. Allografts involve taking bone from a donor and transplanting it to the recipient. Synthetic bone grafts are made from materials such as ceramics or polymers and are used when there is not enough healthy bone available for transplantation. Bone transplantation is typically performed under general anesthesia and may require a hospital stay for several days. After the procedure, the transplanted bone will need time to heal and integrate with the surrounding tissue. Physical therapy may be recommended to help the patient regain strength and mobility in the affected area.

Bone diseases refer to a group of medical conditions that affect the structure, strength, and function of bones. These diseases can be caused by a variety of factors, including genetics, hormonal imbalances, vitamin and mineral deficiencies, infections, and injuries. Some common bone diseases include osteoporosis, osteogenesis imperfecta, Paget's disease, and bone cancer. Osteoporosis is a condition characterized by weak and brittle bones that are prone to fractures, especially in the spine, hip, and wrist. Osteogenesis imperfecta is a genetic disorder that causes bones to be abnormally weak and brittle, leading to frequent fractures and deformities. Paget's disease is a chronic disorder that causes bones to become thickened and misshapen due to excessive bone remodeling. Bone cancer, also known as skeletal sarcoma, is a rare type of cancer that starts in the bone or bone marrow. Treatment for bone diseases depends on the specific condition and its severity. It may include medications, lifestyle changes, physical therapy, and in some cases, surgery. Early detection and treatment are important for preventing complications and improving outcomes.

In the medical field, "bone nails" typically refer to a type of internal fixation device used in orthopedic surgery to stabilize fractures or other injuries to long bones. Bone nails are typically made of metal and are inserted into the bone through a small incision, where they are used to hold the broken bone fragments in place while they heal. There are several types of bone nails, including intramedullary nails, which are inserted into the center of the bone, and external fixators, which are attached to the bone on the outside. Bone nails are commonly used to treat fractures of the femur, tibia, and humerus, as well as other long bones in the body. The use of bone nails can help to reduce the risk of complications associated with open fractures, such as infection, and can also help to speed up the healing process. However, as with any surgical procedure, there are potential risks and complications associated with the use of bone nails, and patients should discuss these with their healthcare provider before undergoing the procedure.

Spinal curvatures refer to the natural curves that exist in the spine. The spine has three main curves: the cervical curve (at the neck), the thoracic curve (in the chest), and the lumbar curve (in the lower back). These curves help to distribute the weight of the body and provide flexibility and stability to the spine. In the medical field, spinal curvatures are important for diagnosing and treating spinal conditions such as scoliosis, kyphosis, and lordosis. Scoliosis is a condition in which the spine has an abnormal curvature to one side, while kyphosis is a curvature of the spine that causes the upper back to become hunched forward. Lordosis is a curvature of the spine that causes the lower back to become excessively curved. Abnormal spinal curvatures can cause pain, discomfort, and decreased mobility. Treatment options may include physical therapy, bracing, and surgery, depending on the severity of the condition.

Tibial fractures are breaks or fractures in the tibia, which is the larger of the two bones in the lower leg. The tibia is located between the knee and ankle and is responsible for supporting the weight of the body. Tibial fractures can occur as a result of trauma, such as a fall or a car accident, or as a complication of osteoporosis or other bone diseases. Symptoms of a tibial fracture may include pain, swelling, bruising, and difficulty bearing weight on the affected leg. Treatment for tibial fractures may include immobilization with a cast or brace, surgery to repair the fracture, and physical therapy to help the bone heal and regain strength.

In the medical field, "Fractures, Closed" refers to a type of bone injury where the bone is broken but the skin remains intact and there is no open wound or bleeding. This type of fracture is also known as a "closed fracture" or a "simple fracture." Closed fractures can be caused by a variety of factors, including falls, accidents, sports injuries, and even some medical conditions such as osteoporosis. Symptoms of a closed fracture may include pain, swelling, tenderness, and difficulty moving the affected area. Treatment for closed fractures typically involves immobilizing the affected bone with a cast or brace to allow it to heal properly. In some cases, surgery may be necessary to realign the broken bone and ensure proper healing. It is important to seek medical attention for a suspected closed fracture to prevent complications and ensure proper treatment.

In the medical field, bone plates are surgical implants used to stabilize and repair fractures or other injuries to bones. They are typically made of metal, such as titanium or stainless steel, and are designed to fit precisely onto the bone to provide support and promote healing. Bone plates are usually secured to the bone using screws, pins, or other types of fixation devices. They can be used to treat a wide range of bone injuries, including fractures, dislocations, and osteotomies (surgical cuts made in bones to realign them). The use of bone plates has revolutionized the treatment of bone injuries, allowing for faster and more accurate healing, and reducing the risk of complications such as nonunion (failure of the bone to heal) or malunion (healing of the bone in the wrong position).

Joint instability refers to a condition in which the bones of a joint are not able to maintain their normal position and alignment. This can occur due to injury, disease, or other factors that cause the ligaments, tendons, or muscles that support the joint to become weakened or damaged. Joint instability can result in pain, swelling, and difficulty moving the affected joint. In severe cases, it can lead to long-term disability and chronic pain. Treatment for joint instability may include physical therapy, bracing, or surgery, depending on the severity of the condition.

Bone regeneration is the process by which the body repairs and replaces damaged or lost bone tissue. This process involves the formation of new bone cells, or osteoblasts, which secrete a matrix of collagen and minerals that eventually hardens into bone. Bone regeneration is a natural process that occurs throughout life, but it can also be stimulated by medical treatments such as bone grafts or growth factors. In some cases, bone regeneration may be necessary to treat conditions such as fractures, osteoporosis, or bone tumors.

Bone lengthening, also known as limb lengthening or distraction osteogenesis, is a surgical procedure used to increase the length of a bone. This procedure is typically performed to correct limb length discrepancies, such as those caused by a congenital defect, a fracture that did not heal properly, or a difference in leg length that has caused chronic pain or other problems. During the procedure, a device called an external fixator is attached to the bone above and below the area where lengthening is desired. The fixator is then gradually tightened over a period of several weeks, causing the bone to slowly lengthen. This process is called distraction osteogenesis. Bone lengthening can be a complex and time-consuming procedure, and it is typically only recommended for patients who have significant limb length discrepancies that cannot be corrected with other methods. The procedure may also be associated with some risks and complications, such as infection, nerve damage, and blood clots. However, when performed by a skilled surgeon, bone lengthening can be an effective way to improve a patient's quality of life and alleviate chronic pain.

Arthroplasty, Replacement, Knee is a surgical procedure in which the damaged or diseased knee joint is replaced with an artificial joint made of metal, plastic, or ceramic. The procedure is typically performed to relieve pain, improve mobility, and restore function to the knee joint. During the surgery, the damaged or diseased parts of the knee joint are removed, and the artificial joint is implanted in their place. The artificial joint is usually made up of a metal femoral component, a plastic tibial component, and a polyethylene insert that sits between them. There are several types of knee arthroplasty, including total knee arthroplasty, partial knee arthroplasty, and unicompartmental knee arthroplasty. The type of arthroplasty that is recommended depends on the severity of the knee damage and the patient's overall health. Knee arthroplasty is a common surgical procedure that is performed to treat a variety of knee conditions, including osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis. It is generally considered to be a safe and effective treatment option for patients who are experiencing chronic knee pain and have tried other non-surgical treatments without success.

Lordosis is a medical term that refers to an abnormal curvature of the spine, specifically a forward curvature of the lower back. It is also known as swayback or hyperlordosis. Lordosis can be caused by a variety of factors, including poor posture, muscle imbalances, injury, or certain medical conditions such as osteoporosis or scoliosis. In some cases, lordosis may be asymptomatic and not require treatment, while in other cases it may cause pain, discomfort, or other symptoms. Treatment for lordosis may include physical therapy, exercise, and in some cases, surgery.

Biomechanical phenomena refer to the study of the mechanical properties and behavior of living organisms, particularly in relation to movement and function. In the medical field, biomechanical phenomena are often studied in the context of musculoskeletal disorders, sports injuries, and rehabilitation. This involves analyzing the forces and movements involved in various activities, such as walking, running, or lifting, and how they affect the body's tissues and structures. Biomechanical engineers and researchers use a variety of techniques, including computer simulations, imaging technologies, and physical measurements, to study biomechanical phenomena and develop new treatments and interventions for a range of medical conditions.

Bone anteversion refers to the degree to which the head of a bone rotates medially (towards the midline of the body) relative to the shaft of the bone. It is a normal anatomical variation that can affect various bones in the body, including the femur (thigh bone), tibia (shin bone), and pelvis. In the pelvis, bone anteversion refers to the degree to which the acetabulum (socket that holds the hip joint) is tilted medially relative to the rest of the pelvis. This can affect the mechanics of the hip joint and may contribute to conditions such as hip dysplasia or osteoarthritis. In the femur, bone anteversion refers to the degree to which the head of the femur rotates medially relative to the shaft of the bone. This can affect the mechanics of the knee joint and may contribute to conditions such as patellofemoral pain syndrome or anterior cruciate ligament (ACL) injury. In the tibia, bone anteversion refers to the degree to which the medial condyle (the rounded end of the bone that articulates with the femur) rotates medially relative to the shaft of the bone. This can affect the mechanics of the knee joint and may contribute to conditions such as tibial torsion or ankle instability. Overall, bone anteversion is an important factor to consider in the diagnosis and treatment of various musculoskeletal conditions.

In the medical field, the bone matrix is the non-cellular component of bone tissue. It is a complex network of proteins and minerals that provides the structural support and strength to the bone. The bone matrix is composed of two main components: the organic matrix and the inorganic matrix. The organic matrix is made up of collagen fibers, which are the most abundant protein in the bone matrix. Collagen fibers provide flexibility and tensile strength to the bone. The inorganic matrix is made up of hydroxyapatite crystals, which are mineralized calcium phosphate. Hydroxyapatite crystals provide rigidity and compressive strength to the bone. The bone matrix is constantly being remodeled through a process called bone turnover. This process involves the removal of old bone matrix by osteoclasts (bone-resorbing cells) and the formation of new bone matrix by osteoblasts (bone-forming cells). This process is essential for maintaining the health and strength of bone tissue.

Bone marrow transplantation (BMT) is a medical procedure in which healthy bone marrow is transplanted into a patient who has damaged or diseased bone marrow. The bone marrow is the spongy tissue found inside bones that produces blood cells, including red blood cells, white blood cells, and platelets. There are two main types of bone marrow transplantation: autologous and allogeneic. Autologous BMT involves transplanting bone marrow from the patient's own body, usually after it has been harvested and stored before the patient undergoes high-dose chemotherapy or radiation therapy to destroy their diseased bone marrow. Allogeneic BMT involves transplanting bone marrow from a donor who is a genetic match for the patient. BMT is used to treat a variety of conditions, including leukemia, lymphoma, multiple myeloma, sickle cell anemia, and some inherited blood disorders. The procedure can also be used to treat certain immune system disorders and some genetic diseases. The success of BMT depends on several factors, including the type and stage of the patient's disease, the patient's overall health, and the availability of a suitable donor. The procedure can be complex and may involve several stages, including preparatory treatment, the actual transplantation, and post-transplantation care.

Femoral fractures are breaks or fractures that occur in the femur, which is the longest and strongest bone in the human body. The femur is located in the thigh and is responsible for supporting the weight of the body and facilitating movement of the lower limbs. Femoral fractures can occur as a result of a direct blow to the thigh, a fall from a height, or a severe impact during a motor vehicle accident. They can also occur as a complication of osteoporosis, a condition that weakens bones and makes them more susceptible to fractures. Femoral fractures can be classified based on their location, severity, and the presence of any associated injuries. Some common types of femoral fractures include: 1. Intertrochanteric fractures: These occur in the region between the greater and lesser trochanters, which are bony projections on the femur. 2. Subtrochanteric fractures: These occur below the greater trochanter and are often associated with a high risk of complications. 3. Femoral neck fractures: These occur at the junction between the shaft and the neck of the femur and are often associated with a high risk of complications, including nonunion and avascular necrosis. 4. Shaft fractures: These occur in the middle of the femur and can be caused by a direct blow or a fall from a height. Femoral fractures can be treated with a variety of methods, including surgery, casting, and physical therapy. The choice of treatment depends on the severity of the fracture, the patient's overall health, and the presence of any associated injuries. In some cases, surgery may be necessary to realign the bones and stabilize the fracture, while in other cases, casting or physical therapy may be sufficient for proper healing.

In the medical field, a dislocation refers to a condition in which a bone is displaced from its normal position in the joint. This can occur when the ligaments or muscles that hold the bone in place are torn or stretched beyond their normal limits, causing the bone to move out of alignment. Dislocations can occur in any joint in the body, but they are most common in the shoulder, elbow, hip, and knee. Symptoms of a dislocation may include severe pain, swelling, and difficulty moving the affected joint. In some cases, a dislocation may also be accompanied by a "pop" or "click" sound, and the affected area may appear deformed or misshapen. Treatment for a dislocation typically involves reducing the joint back into its proper position and immobilizing it to allow the ligaments and muscles to heal. In some cases, surgery may be necessary to repair torn ligaments or stabilize the joint. It is important to seek medical attention immediately if you suspect that you or someone else may have a dislocation, as untreated dislocations can lead to long-term joint damage and disability.

The ankle joint is a complex joint located at the lower end of the leg and the upper end of the foot. It is formed by the articulation between the talus bone of the foot and the tibia and fibula bones of the leg. The ankle joint is responsible for allowing movement in the foot and ankle, including dorsiflexion (lifting the front of the foot), plantarflexion (dropping the heel), inversion (turning the foot inward), and eversion (turning the foot outward). The ankle joint is also supported by ligaments, which help to stabilize the joint and prevent excessive movement. Injuries to the ankle joint, such as sprains or fractures, can result in pain, swelling, and limited mobility.

Heart septal defects, ventricular, refer to a type of congenital heart defect that affects the ventricles, which are the lower chambers of the heart responsible for pumping blood out to the body. In a healthy heart, there is a wall called the septum that separates the left and right ventricles. However, in a person with a ventricular septal defect, there is a hole or opening in this wall, allowing blood to flow from one ventricle to the other. This can lead to a variety of symptoms, depending on the size and location of the defect. Some people may not experience any symptoms at all, while others may experience shortness of breath, fatigue, chest pain, or heart palpitations. In severe cases, a ventricular septal defect can lead to heart failure or other complications. Treatment for ventricular septal defects typically involves surgical repair or the placement of a device to close the hole in the septum. The specific treatment approach will depend on the size and location of the defect, as well as the individual's overall health and medical history.

In the medical field, bone substitutes are materials that are used to replace or repair damaged or diseased bone tissue. These materials can be used in a variety of surgical procedures, including fracture repair, spinal fusion, and dental implants. Bone substitutes can be classified into two main categories: autografts and allografts. Autografts are bone grafts taken from the patient's own body, while allografts are bone grafts taken from a donor. There are also synthetic bone substitutes, which are man-made materials that are designed to mimic the properties of natural bone. These materials can include ceramics, polymers, and composites. The choice of bone substitute depends on the specific surgical procedure and the patient's individual needs. Factors such as the location and severity of the bone damage, the patient's age and overall health, and the availability of autografts or allografts may all influence the choice of bone substitute.

Bone diseases, metabolic, refer to a group of disorders that affect the normal metabolism of bone tissue, leading to changes in bone structure and strength. These diseases can be caused by a variety of factors, including genetic mutations, hormonal imbalances, vitamin and mineral deficiencies, and certain medications. Some common examples of metabolic bone diseases include: 1. Osteoporosis: A condition characterized by low bone density and increased risk of fractures. 2. Osteogenesis imperfecta: A genetic disorder that causes bones to be weak and brittle, leading to frequent fractures. 3. Hyperparathyroidism: A condition in which the parathyroid glands produce too much parathyroid hormone, leading to increased bone resorption and decreased bone density. 4. Hypoparathyroidism: A condition in which the parathyroid glands produce too little parathyroid hormone, leading to decreased bone resorption and increased bone density. 5. Rickets: A condition that primarily affects children and is characterized by soft, weak bones due to a lack of vitamin D or calcium. 6. Osteomalacia: A condition that primarily affects adults and is characterized by soft, weak bones due to a lack of vitamin D or calcium. Treatment for metabolic bone diseases typically involves addressing the underlying cause of the disorder, such as correcting vitamin or mineral deficiencies, treating hormonal imbalances, or surgically removing or replacing affected bones. In some cases, medications may also be prescribed to help prevent or slow the progression of bone loss.

Fractures, bone refer to a break or crack in a bone that occurs due to trauma or injury. Fractures can be classified based on their severity, location, and type. There are several types of bone fractures, including: 1. Simple fractures: These are clean breaks in the bone with no displacement of the broken ends. 2. Compound fractures: These are breaks in the bone that involve the skin and/or soft tissues surrounding the bone. 3. Comminuted fractures: These are fractures in which the bone is broken into multiple pieces. 4. Stress fractures: These are small cracks in the bone that occur due to repetitive stress or overuse. 5. Open fractures: These are fractures in which the broken bone pierces through the skin. 6. Closed fractures: These are fractures in which the broken bone is contained within the skin. The treatment for bone fractures depends on the severity and location of the fracture, as well as the patient's overall health. Treatment options may include rest, ice, compression, and elevation (RICE), casting, surgery, or physical therapy.

Postoperative complications are adverse events that occur after a surgical procedure. They can range from minor issues, such as bruising or discomfort, to more serious problems, such as infection, bleeding, or organ damage. Postoperative complications can occur for a variety of reasons, including surgical errors, anesthesia errors, infections, allergic reactions to medications, and underlying medical conditions. They can also be caused by factors such as poor nutrition, dehydration, and smoking. Postoperative complications can have serious consequences for patients, including prolonged hospital stays, additional surgeries, and even death. Therefore, it is important for healthcare providers to take steps to prevent postoperative complications and to promptly recognize and treat them if they do occur.

Bone morphogenetic proteins (BMPs) are a group of signaling proteins that play a crucial role in the development and maintenance of bone tissue. They are secreted by various cells in the body, including bone-forming cells called osteoblasts, and are involved in processes such as bone growth, repair, and remodeling. BMPs are also used in medical treatments to promote bone growth and healing. For example, they are sometimes used in orthopedic surgeries to help repair fractures or to stimulate the growth of new bone in areas where bone has been lost, such as in spinal fusion procedures. They may also be used in dental procedures to help promote the growth of new bone in areas where teeth have been lost. BMPs are also being studied for their potential use in other medical applications, such as in the treatment of osteoporosis, a condition characterized by weak and brittle bones, and in the repair of damaged or diseased tissues in other parts of the body.

Articular cartilage is a type of connective tissue that covers the ends of bones in synovial joints, such as the knee, hip, and shoulder. It is a smooth, slippery tissue that provides a cushioning effect between the bones, allowing them to move smoothly and with minimal friction. Articular cartilage is composed of cells called chondrocytes, which produce and maintain the matrix of the tissue, as well as a network of collagen fibers that provide strength and support. The matrix of articular cartilage is rich in water and proteoglycans, which give it its characteristic smooth, slippery texture. Articular cartilage is essential for the proper functioning of synovial joints, as it helps to reduce friction and absorb shock during movement. However, it is also prone to damage and degeneration, which can lead to conditions such as osteoarthritis.

Bone Morphogenetic Protein 2 (BMP2) is a protein that plays a crucial role in bone development and repair. It is a member of the transforming growth factor-beta (TGF-β) superfamily of proteins, which are involved in a wide range of cellular processes, including cell growth, differentiation, and migration. In the medical field, BMP2 is used as a therapeutic agent to promote bone growth and regeneration in a variety of conditions, including spinal fusion, non-unions, and osteoporosis. It is typically administered as a bone graft substitute or in combination with other growth factors to enhance bone formation. BMP2 has also been studied for its potential use in tissue engineering and regenerative medicine, where it is used to stimulate the growth of new bone tissue in vitro and in vivo. Additionally, BMP2 has been shown to have anti-inflammatory and anti-cancer effects, making it a promising target for the development of new therapies for a range of diseases.
