Synovial chondromatosis in the temporomandibular joint complicated by displacement and calcification of the articular disk: report of two cases. (1/4)Two cases of synovial chondromatosis of the temporomandibular joint (TMJ) are presented, including correlation of CT and MR imaging characteristics with surgical and pathologic findings. The usefulness of CT and MR imaging in the diagnosis of TMJ disorders is discussed. (+info)
Symptomatic laryngeal nodular chondrometaplasia: a clinicopathological study. (2/4)A 41 year old man with a history of politrauma presented with a nodular mass of the left false vocal cord, associated with progressive dysphonia, dyspnoea, and dysphagia. A computed tomography scan of the neck region showed a rounded and circumscribed mass without infiltration of the surrounding tissues. Histological investigation of the nodule revealed the presence of fibroelastic cartilaginous tissue, surrounded by a thin rim of fibrous tissue, with rare hypercellular areas, occasional binucleated cells, slight hyperchromasia, and an irregular nuclear profile. Mitotic activity was absent. The patient's history of laryngeal trauma, with the subsequent progressive onset of clinical symptoms, helps to distinguish the chondrometaplastic nature of this nodule from true laryngeal cartilaginous tumours, such as chondroma and low grade chondrosarcoma.

A case of chondromatosis indicates a synovial stem cell aetiology. (3/4)OBJECTIVE: To evaluate cell cultures derived from intrasynovial nodules from a patient with primary synovial chondromatosis (PSC) for aberrant numbers/differentiation of osteochondroprogenitor cells. METHODS: Cell cultures were established from PSC synovial nodules, or normal bovine or human osteoarthritis (OA) synovia (for comparison). Multi-lineage potential was determined using well-characterized in vitro culture systems to assess osteogenic, chondrogenic and adipogenic capability. RESULTS: Primary PSC cell cultures were typically fibroblastic but contained islands of dense cell clusters/nodules, some of which were isolated and cultured separately [putative osteochondroprogenitris (pOCP) cultures]. OA synovial cultures had barely detectable levels of alkaline phosphatase (AP) that increased (0.006+/-0.008 to 0.141+/-0.000 nmol p-nitrophenol/min/cm(2)) with dexamethasone treatment. AP activity was higher in primary PSC cell cultures and further enhanced by dexamethasone (from 0.076+/-0.022 to 5.735+/-0.000 nmol p-nitrophenol/min/cm(2)). Histochemically, AP was localized as discreet areas within PSC cultures. No AP activity was detected histochemically in OA or normal bovine synovial cultures. The pOCP cultures had high basal AP (5.036+/-0.439 nmol p-nitrophenol/min/cm(2)) and spontaneously formed mineralized nodules, which increased in number under standard osteogenic conditions. Under chondrogenic conditions, micromass or pellet-cultured pOCP cells spontaneously synthesized a matrix containing glycosaminoglycans and collagen II. In adipogenic medium, the number of lipid-containing cells was increased. CONCLUSIONS: Compared with cultures established from OA or normal synovia, cell cultures established from PSC synovial nodules were enriched in osteochondroprogenitors, which, unlike normal mesenchymal cells, differentiated along chondrogenic and osteogenic lineages in the absence of dexamethasone.

Chondromyxoid fibroma of the seventh cervical vertebra. (4/4)Chondromyxoid fibroma is a rare benign bone tumor representing less than 0.5% of all bone tumors. It commonly involves the long tubular bones. Involvement of the spine is rare. A 35-year-old man presented with history of neck pain, restriction of neck movements, pain and numbness along the medial aspect of the left forearm and weakness with wasting of the left hand. A presumptive diagnosis of a bony tumor such as an aneurysmal bone cyst or a giant cell tumor involving the seventh vertebral body was made on plain X-rays, MRI and bone scan. He underwent C7 central corpectomy, incomplete intralesional curettage with iliac bone grafting and C6 to T1 interspinous wiring. The histological diagnosis was chondromyxoid fibroma. On eight years' follow-up, CT scan showed no progression of the tumor with good alignment and fusion of the graft at the site of the corpectomy. The authors conclude that corpectomy and iliac bone grafting for chondromyxoid fibroma has a good outcome on long-term follow-up. (+info)
Synovial chondromatosis is a rare condition that affects the synovial membrane, which is the lining of joints, bursae (fluid-filled sacs that cushion bones), and tendon sheaths. In this condition, nodules made up of cartilage form in the synovial membrane. These nodules can detach from the synovial membrane and float freely in the synovial fluid, which lubricates the joint. If they become numerous, they can cause joint pain, stiffness, and decreased range of motion. In some cases, the loose bodies may also cause locking or catching sensations in the joint. Surgery is typically required to remove the cartilaginous nodules and relieve symptoms. If left untreated, synovial chondromatosis can lead to osteoarthritis and other joint problems.
Chondromatosis is a medical condition characterized by the abnormal formation of multiple cartilaginous nodules or masses within a joint or soft tissue. It is often seen in synovial joints, where the synovial membrane that lines the joint cavity produces these cartilage nodules.
There are two types of chondromatosis: primary and secondary. Primary chondromatosis, also known as synovial chondromatosis, is a rare condition where the cartilaginous nodules develop spontaneously within the synovium. Over time, these nodules may calcify or ossify, turning into bone-like structures. Secondary chondromatosis occurs as a result of degenerative joint disease, trauma, or other underlying conditions that cause cartilage to break off and float freely in the synovial fluid, eventually forming nodules.
Symptoms of chondromatosis may include joint pain, swelling, stiffness, and limited range of motion. In some cases, the condition may lead to osteoarthritis or other joint complications if left untreated. Treatment typically involves surgical removal of the cartilaginous nodules, followed by management of any underlying conditions that may have contributed to the development of chondromatosis.
'Joint loose bodies' refer to free-floating fragments or particles within the joint space. These can be composed of cartilage, bone, or other synovial tissue debris. They can vary in size and number and may cause symptoms such as pain, locking, catching, or decreased range of motion due to mechanical interference with joint movement. Joint loose bodies are often associated with degenerative joint diseases like osteoarthritis but can also result from trauma or previous surgeries.
A chondroma is a benign, slow-growing tumor that develops in the cartilage. Cartilage is a type of connective tissue found in various parts of the body, including the joints, ribcage, and nose. Chondromas are most commonly found in the hands and feet.
Chondromas are typically small, measuring less than 2 centimeters in diameter, and they usually do not cause any symptoms. However, if a chondroma grows large enough to press on nearby nerves or blood vessels, it may cause pain, numbness, or weakness in the affected area.
Chondromas are usually diagnosed through imaging tests such as X-rays, CT scans, or MRI scans. If a chondroma is suspected based on these tests, a biopsy may be performed to confirm the diagnosis and rule out other types of tumors.
Treatment for chondromas typically involves surgical removal of the tumor. In most cases, this can be done using minimally invasive techniques that allow for quicker recovery times. After surgery, patients will need to follow up with their healthcare provider to ensure that the tumor has been completely removed and to monitor for any signs of recurrence.
The middle cranial fossa is a depression or hollow in the skull that forms the upper and central portion of the cranial cavity. It is located between the anterior cranial fossa (which lies anteriorly) and the posterior cranial fossa (which lies posteriorly). The middle cranial fossa contains several important structures, including the temporal lobes of the brain, the pituitary gland, the optic chiasm, and the cavernous sinuses. It is also where many of the cranial nerves pass through on their way to the brain.
The middle cranial fossa can be further divided into two parts: the anterior and posterior fossae. The anterior fossa contains the optic chiasm and the pituitary gland, while the posterior fossa contains the temporal lobes of the brain and the cavernous sinuses.
The middle cranial fossa is formed by several bones of the skull, including the sphenoid bone, the temporal bone, and the parietal bone. The shape and size of the middle cranial fossa can vary from person to person, and abnormalities in its structure can be associated with various medical conditions, such as pituitary tumors or aneurysms.
Temporomandibular Joint Disorders (TMD) refer to a group of conditions that cause pain and dysfunction in the temporomandibular joint (TMJ) and the muscles that control jaw movement. The TMJ is the hinge joint that connects the lower jaw (mandible) to the skull (temporal bone) in front of the ear. It allows for movements required for activities such as eating, speaking, and yawning.
TMD can result from various causes, including:
1. Muscle tension or spasm due to clenching or grinding teeth (bruxism), stress, or jaw misalignment
2. Dislocation or injury of the TMJ disc, which is a small piece of cartilage that acts as a cushion between the bones in the joint
3. Arthritis or other degenerative conditions affecting the TMJ
4. Bite problems (malocclusion) leading to abnormal stress on the TMJ and its surrounding muscles
5. Stress, which can exacerbate existing TMD symptoms by causing muscle tension
Symptoms of Temporomandibular Joint Disorders may include:
- Pain or tenderness in the jaw, face, neck, or shoulders
- Limited jaw movement or locking of the jaw
- Clicking, popping, or grating sounds when moving the jaw
- Headaches, earaches, or dizziness
- Difficulty chewing or biting
- Swelling on the side of the face
Treatment for TMD varies depending on the severity and cause of the condition. It may include self-care measures (like eating soft foods, avoiding extreme jaw movements, and applying heat or cold packs), physical therapy, medications (such as muscle relaxants, pain relievers, or anti-inflammatory drugs), dental work (including bite adjustments or orthodontic treatment), or even surgery in severe cases.
An arthroscope is a medical device that is used during minimally invasive surgical procedures. It is a thin, flexible tube with a light and camera on the end, which allows surgeons to visualize the inside of a joint without making a large incision. This enables them to diagnose and treat various joint conditions, such as torn cartilage or ligaments, inflamed synovial tissue, and bone spurs. The images captured by the arthroscope are displayed on a monitor in the operating room, helping the surgeon guide their instruments and perform the procedure with great precision. Arthroscopy is commonly used for joints such as the knee, shoulder, hip, ankle, and wrist.
The metacarpophalangeal (MCP) joint is the joint that connects the bones of the hand (metacarpals) to the bones of the fingers and thumb (phalanges). It's also commonly referred to as the "knuckle" joint. The MCP joint allows for flexion, extension, abduction, and adduction movements of the fingers and thumb. It is a synovial joint, which means it contains a lubricating fluid called synovial fluid that helps reduce friction during movement.
Chondrosarcoma is a type of cancer that develops in the cartilaginous tissue, which is the flexible and smooth connective tissue found in various parts of the body such as the bones, ribs, and nose. It is characterized by the production of malignant cartilage cells that can invade surrounding tissues and spread to other parts of the body (metastasis).
Chondrosarcomas are typically slow-growing tumors but can be aggressive in some cases. They usually occur in adults over the age of 40, and men are more commonly affected than women. The most common sites for chondrosarcoma development include the bones of the pelvis, legs, and arms.
Treatment for chondrosarcoma typically involves surgical removal of the tumor, along with radiation therapy or chemotherapy in some cases. The prognosis for chondrosarcoma depends on several factors, including the size and location of the tumor, the grade of malignancy, and whether it has spread to other parts of the body.
Panoramic radiography is a specialized type of dental X-ray imaging that captures a panoramic view of the entire mouth, including the teeth, upper and lower jaws, and surrounding structures. It uses a special machine that rotates around the head, capturing images as it moves. This technique provides a two-dimensional image that is helpful in diagnosing and planning treatment for various dental conditions such as impacted teeth, bone abnormalities, and jaw disorders.
The panoramic radiograph can also be used to assess the development and positioning of wisdom teeth, detect cysts or tumors in the jaws, and evaluate the effects of trauma or injury to the mouth. It is a valuable tool for dental professionals as it allows them to see a comprehensive view of the oral structures, which may not be visible with traditional X-ray techniques.
It's important to note that while panoramic radiography provides valuable information, it should be used in conjunction with other diagnostic tools and clinical examinations to ensure accurate diagnosis and treatment planning.
The synovial membrane, also known as the synovium, is the soft tissue that lines the inner surface of the capsule of a synovial joint, which is a type of joint that allows for smooth movement between bones. This membrane secretes synovial fluid, a viscous substance that lubricates and nourishes the cartilage and helps to reduce friction within the joint during movement.
The synovial membrane has a highly specialized structure, consisting of two layers: the intima and the subintima. The intima is a thin layer of cells that are in direct contact with the synovial fluid, while the subintima is a more fibrous layer that contains blood vessels and nerves.
The main function of the synovial membrane is to produce and regulate the production of synovial fluid, as well as to provide nutrients to the articular cartilage. It also plays a role in the immune response within the joint, helping to protect against infection and inflammation. However, abnormalities in the synovial membrane can lead to conditions such as rheumatoid arthritis, where the membrane becomes inflamed and produces excess synovial fluid, leading to pain, swelling, and joint damage.
