M24.5: Contracture of joint

Contracture of a joint refers to the persistent, often permanent, contraction of a muscle that causes a deformity of a joint, leading to impaired function and movement. This condition can stem from multiple causes including prolonged immobility, nerve damage, or conditions such as muscular dystrophy. The symptoms can greatly vary in severity, from mild stiffness to complete loss of the ability to move the joint. The joint involved might be visibly deformed or displaced, and there may be associated discomfort or pain. Contracture predominantly affects the mobility of the joint and may progressively worsen without intervention. It's important to understand that this condition doesn't just affect the joint itself, but also the surrounding structures including muscles and ligaments.
