Erect (luxatio erecta) and superior glenohumeral dislocations are extremely uncommon. In luxatio erecta, the humeral head is subglenoid or subcoracoid just as in the more common anterior dislocation, but the shaft of the humerus is parallel to the spine of the scapula, not parallel to the chest wall as seen in the anterior type. Superior dislocations have the humeral head overlying the acromion or the clavicle on the anteroposterior radiograph. Radiographic findings in seven cases are presented and some of the associated complications are discussed.
肩关节直立位脱位（直立性脱位）和肩肱关节上脱位极为罕见。在直立性脱位中，肱骨头位于肩胛下或喙突下，与较常见的前脱位情况相同，但肱骨干与肩胛冈平行，而非如前脱位类型那样与胸壁平行。在上脱位时，前后位X线片显示肱骨头位于肩峰或锁骨上方。本文报告了7例的影像学表现，并讨论了一些相关并发症。
