Treatment Body fractures Surgery is not necessary. The patient wears a sling for comfort, and from the start practises active exercises to the shoulder, elbow and fingers. Isolated glenoid neck fractures The fracture is usually impacted and the glenoid surface is intact. A sling is worn for comfort and early exercises are begun. Intra-articular fractures Type I glenoid fractures, if displaced, may result in instability of the shoulder. If the fragment involves more than a third of the glenoid surface and is displaced by more than 5 mm surgical fixation should be considered. Anterior rim fractures are approached through a delto-pectoral incision and posterior rim fractures through the posterior approach. Type II fractures are associated with inferior subluxation of the head of the humerus and require open reduction and internal fixation. Types III, IV, V and VI fractures have poorly defined indications for surgery. Generally speaking, if the head is centred on the major portion of the glenoid and the shoulder is stable a non-operative approach is adopted. Comminuted fractures of the glenoid fossa are likelyto lead to osteoarthritis in the longer term. Fractures of the acromion Undisplaced fractures are treated non-operatively. Only Type III acromial fractures, in which the subacromial space is reduced, require operative intervention to restore the anatomy. Fractures of the coracoid process Fractures distal to the coracoacromial ligaments do not result in serious anatomical displacement; those proximal to the ligaments are usually associated with acromioclavicular separations and may need operative treatment. Combined fractures Whereas an isolated fracture of the glenoid neck is stable, if there is an associated fracture of the clavicle or disruption of the acromioclavicular ligament the glenoid mass may become markedly displaced giving rise to a ‘floating shoulder’ (Williams et al, 2001). Diagnosis can be difficult and may require advanced imaging and three-dimensional reconstructions. At least one of the injuries (and sometimes both) will need operative fixation before the fragments are stabilized. ---from 《Apley’s System of Orthopaedics and Fractures》P736-737 重点词汇整理： sling吊带 the fragment involves more than a third of the glenoid surface and is displaced by more than 5 mm 骨折碎片占关节盂表面的三分之一以上，移位超过5毫米 rim /rɪm/n. 边，边缘 incision /ɪnˈsɪʒn/n. 切口；入路；雕刻，切割；切开 posterior approach后方入路 subluxation /,sʌblʌk'seiʃən/n.
