In cases of dislocation of the shoulder the humeral head almost always dislocates anteriorly. Only rarely does the dislocation result in a posterior position of all or part of the humeral head. The diagnosis of posterior dislocation is not always as easy as the diagnosis of anterior dislocation and for this reason the injury is often missed. Cisternino et al. found that over 50% of patients with posterior dislocation of the shoulder were missed on initial examination. The longer the time between accident and treatment, the more difficult that treatment becomes and the harder it is to achieve a satisfactory functional result. Therefore it is vital to think of this injury in all cases of severe contusion of the shoulder and if there is the slightest suspicion of this injury, the patient must be aggressively investigated to establish the relationship between the humeral head and the glenoid.
在肩关节脱位的病例中，肱骨头几乎总是向前脱位。只有极少数情况下，脱位会导致肱骨头全部或部分处于后位。后脱位的诊断并不总是像前脱位那么容易，因此这种损伤常常被漏诊。西斯泰尔尼诺等人发现，超过50%的肩关节后脱位患者在初次检查时被漏诊。事故与治疗之间的时间间隔越长，治疗就越困难，要获得满意的功能结果也就越难。因此，在所有肩部严重挫伤的病例中都必须考虑到这种损伤，如果对这种损伤有丝毫怀疑，就必须积极对患者进行检查，以确定肱骨头与关节盂之间的关系。
