The area where habitual dislocations often occur is the habitual dislocation of the shoulder joint. If the shoulder joint is repeatedly dislocated, it is important to suspect if there is a plaque injury to the joint pelvis. The best thing to do is to do a CT 3D reconstruction of the shoulder joint to see if there is a bony defect in the joint pelvis. If there is a bony defect in the pelvis, surgery may be necessary to reconstruct the anatomical structure of the pelvis to ensure the stability of the shoulder joint. An MRI of the shoulder joint will be done to see if there is damage to the humeral head, cartilage of the pelvis, and the rotator cuff. If there is damage to the rotator cuff, it can also affect the stability of the shoulder joint, which can cause habitual dislocation of the shoulder off. If the shoulder capsule is significantly damaged causing joint instability, arthroscopic techniques can be used to reconstruct the shoulder capsule as well as repair the rotator cuff to achieve stability of the shoulder joint and avoid habitual shoulder dislocation.
