It is indeed a tragedy that patients with anterior shoulder dislocation progress from the initial dislocation to a “full defect”. Although there is a technique called “Manchu Manchu” to address the “tenfold defect”, preventive measures to avoid “Manchu Manchu Manchu” are still the best policy. The recurrence of a tenfold defect is mainly due to the recurrence of dislocation and improper treatment, so measures need to be taken at these two stages. First of all, some patients with primary dislocations need to be actively treated surgically: 1. Patients with large bone defects in the scapular glenoid or humeral head detected by X-ray, CT or MRI; 2. Patients with fractures and displacement of the scapular glenoid detected by X-ray, CT or MRI (some studies found that displaced scapular glenoid fractures are quickly absorbed if not fixed in time); 3. 4. Patients with a combined rotator cuff injury; 5. Patients with a displaced humeral tuberosity avulsion fracture; 6. Patients who are young, frequently swing their arms backwards, or play antagonistic sports; 7. Patients who experience shoulder instability or pain when swinging their arms backwards. If surgery is required for either primary or recurrent shoulder dislocations, it is important to fully understand the patient’s structural deficits before surgery and take appropriate countermeasures, as oversimplification or random repair surgery may lead to failure of surgical treatment and ultimately serious structural deficits.
