Shoulder subluxation may be due to incomplete local repositioning after acute shoulder dislocation, or local muscle atrophy due to local nerve injury or the presence of paralysis itself, etc. Repeated shoulder dislocations and severe damage to the joint capsule may also cause subluxation. If the acute dislocation of the shoulder joint is not completely reset, it is necessary to give a complete reset by manipulation again. If the subluxation is caused by nerve damage or muscle damage that cannot maintain the strength of the shoulder joint. The main purpose is to try to maintain the normal position of the shoulder joint through posture and immobilization. The affected shoulder joint is flexed at 90 degrees against the chest, and then the upper arm and forearm are immobilized to help repair the shoulder capsule and reduce the risk of re-dislocation. In case of severe localized joint capsule damage and recurrent subluxation, the joint capsule can be repaired by surgery for complete healing.
