The shoulder joint is the joint with the widest range of motion and the most unstable structure among the large joints in the body, so it is easy to cause dislocation when trauma occurs. If the shoulder joint dislocation is not treated properly in the initial stage, habitual dislocation may occur. Patients with anterior shoulder dislocation should be treated by emergency room manipulation as soon as possible after the diagnosis is confirmed. Anesthesia may be used to reduce the difficulty of the repositioning, followed by three weeks of rest using a specific branch. However, this conservative treatment is not appropriate for all patients with shoulder dislocations. In patients with shoulder dislocation, there is a type of anterior shoulder dislocation that is associated with a fracture of the anterior border of the scapula, called a bony Bankart injury, which often requires surgical intervention for repositioning and fixation after diagnosis, otherwise the displaced anterior inferior scapular glenoid fracture may heal abnormally or not, which can lead to recurrent anterior shoulder dislocation. Therefore, patients with first-time shoulder dislocations still need to complete CT or MRI examinations after manual repositioning to exclude bony Bankart injuries. For the first occurrence of shoulder dislocation, it is called initial dislocation, and any subsequent occurrence of dislocation is called recurrent shoulder dislocation. Many doctors advocate arthroscopic minimally invasive surgery for initial shoulder dislocations caused by trauma. However, in China, because of the relatively conservative philosophy of doctors and the fact that surgical treatment is often difficult for patients with initial shoulder dislocations, surgery is currently only performed for recurrent shoulder dislocations. There are also some patients who have recurrent shoulder dislocations after trauma and still do not receive surgical treatment, which not only leads to a serious impact on their lives, but also causes severe bone defects on the side of the scapular glenoid due to the repeated dislocations, which eventually makes surgical treatment very difficult. For these patients with large bone defects, minimally invasive arthroscopic treatment is also often ineffective, requiring the removal of autologous or allogeneic bone blocks to fill the defective area and then to repair the torn joint capsule and glenoid labrum, which is also much more invasive than arthroscopic surgery. Therefore, it is recommended that patients with recurrent shoulder dislocations receive timely treatment with minimally invasive arthroscopic surgery.
