Ankylosis is a condition in which two bones in a joint are fused together, causing stiffness and limited movement of the joint. In some cases, the bone fusion can cause the joint to become abnormally shaped, which can lead to pain, instability, and deformity. There are several different types of ankylosis, including osteoarthritis, rheumatoid arthritis, post-traumatic ankylosis, and post-infectious ankylosis.
Osteoarthritis Ankylosis
Osteoarthritis ankylosis is the most common type of ankylosis and is a result of degenerative joint disease. Osteoarthritis is a condition in which the cartilage in the joint wears away, leaving the bones to rub against each other. As the disease progresses, the bones may eventually fuse together. Symptoms of osteoarthritis ankylosis include pain, stiffness, and limited range of motion.
Rheumatoid Arthritis Ankylosis
Rheumatoid arthritis ankylosis is a form of ankylosis caused by the autoimmune disease rheumatoid arthritis. In rheumatoid arthritis, the body's own immune system attacks the joint tissue, leading to inflammation and damage. As the disease progresses, the joint may eventually become fused together. Symptoms of rheumatoid arthritis ankylosis include pain, swelling, and stiffness.
Post-Traumatic Ankylosis
Post-traumatic ankylosis is a form of ankylosis caused by an injury to the joint. This type of ankylosis can occur after a fracture or dislocation of the joint. As the joint heals, the bones may fuse together, leading to stiffness and limited movement. Symptoms of post-traumatic ankylosis include pain, swelling, and stiffness.
Post-Infectious Ankylosis
Post-infectious ankylosis is a type of ankylosis caused by an infection in the joint. This type of ankylosis can occur after an infection such as septic arthritis, tuberculosis, or gout. As the infection progresses, the joint may become fused together. Symptoms of post-infectious ankylosis include pain, swelling, and stiffness.
