Joint dislocation is mainly caused by external forces that cause the joint surfaces to move out of their normal anatomical position, resulting in joint pain and restricted movement. The common causes of joint dislocation are as follows: 1. The human body falls to the side during sports or activities, such as the shoulder joint landing or being hit, causing shoulder dislocation. 2. Improper force or instantaneous explosive force during sports, resulting in changes in the anatomical structure of the joint surface, such as hip or knee dislocation when playing soccer. 3. 4. In elderly patients, as they grow older, the skeletal ligaments begin to degenerate, resulting in ligament relaxation and joint dislocation during muscle contraction, such as dislocation of the jaw joint due to yawning.
