In anterior shoulder dislocation, orthopaedic clinics used to give manual repositioning followed by three weeks of rest, but this conservative treatment is sometimes not appropriate. There is a type of anterior shoulder dislocation that can be associated with a bony Bankart injury, with an incidence of 5.4-44%. Osseous Bankart injury, as the name implies, is a Bankart injury with a bone mass. It is a special type of Bankart injury (anterior inferior glenoid labral injury) that presents as a glenohumeral-glenoid labral complex avulsion accompanied by an anterior scapular glenoid fracture, and often requires surgical intervention for repositioning and fixation after diagnosis, otherwise the displaced anterior inferior scapular glenoid heals abnormally or does not heal, which can easily lead to recurrent Bigliani et al. classified bony Bankart injuries into three types based on the condition of the fracture fragment and the joint capsule. type I is a displaced avulsed bone fragment with an intact joint capsule; type II is a medially displaced bone fragment that heals malformed at the glenoid rim; and type III includes type IIIA with a less than 25% glenoid rim defect and type IIIB with a greater than 25% glenoid rim defect. Because of the small bone mass of bony Bankart injury, hollow nail fixation is not a suitable option for surgical treatment, and wire anchor nail fixation is a better choice. With the continuous development of arthroscopic surgical techniques, arthroscopic repositioning and fixation techniques for bony Bankart injury have gradually matured, through which the bone mass can be anatomically repositioned and provided with reliable fixation. Arthroscopic repositioning and fixation of bony Bankart injuries has traditionally been performed with a single-row wire anchor nailing technique, but in recent years, for some cases with large bone masses, a double-row wire anchor nailing technique has been proposed in order to obtain anatomic repositioning and firm fixation. Therefore, patients with first-time shoulder dislocation still need to improve CT or MRI examination to exclude bony Bankart injury after manual repositioning.
