Ankylosis is loss of mobility of a joint.
The correct answer and explanation is :
The correct answer is Ankylosis.
Explanation (300 words):
Ankylosis is the medical term used to describe the loss of mobility of a joint due to abnormal stiffening and immobility. This condition can result from disease, injury, or surgical procedures. It often occurs when the bones within a joint fuse together, or when the soft tissues around the joint become stiff and inflexible. Ankylosis can affect any joint in the body, but it is most commonly seen in the spine, fingers, and hips.
There are two main types of ankylosis: fibrous ankylosis and bony ankylosis. In fibrous ankylosis, the joint becomes stiff due to fibrous connective tissue, but some slight movement may still be possible. In bony ankylosis, the bones actually fuse together, leading to complete immobility of the joint.
Ankylosis can be caused by various conditions, including arthritis (especially rheumatoid arthritis), trauma, infections like tuberculosis of the joint, or surgical fusion done intentionally to relieve pain or correct deformity. Inflammatory conditions cause the immune system to attack joint tissues, leading to chronic inflammation and, eventually, joint fusion if not properly treated.
The symptoms of ankylosis often include joint pain, swelling, stiffness, and a noticeable reduction in the range of motion. Over time, the joint may become completely immobile. Diagnosis typically involves a physical examination and imaging studies such as X-rays or MRI scans to evaluate the extent of joint damage or fusion.
Treatment depends on the underlying cause and severity. In early stages, physical therapy, medications to reduce inflammation, and exercises can help maintain mobility. In more advanced cases, surgical intervention such as joint replacement or joint fusion might be necessary.
Preventing ankylosis focuses on early and effective management of joint diseases and injuries to preserve joint function and prevent abnormal stiffening.
