[Luxatio erecta of the shoulder. Report of eight cases]

The luxatio erecta is a rare form of shoulder dislocation frequently described in young patients. The purpose of our study is to review the mechanism of this affection as well as its clinical, radiographic and therapeutic features. We also report eight cases of luxatio erecta observed between 1995 and 2006. We report six males and two females with an average age of 40 years. The left shoulder was dislocated in seven cases and a direct mechanism was reported by two patients. All of our cases presented with the typical attitude described for this dislocation; an upper limb in fixed abduction with the hand raised and inability to bring the elbow back to the body. No neurovascular injury was reported in this study. Radiographic examination showed inferior dislocation of the humeral head and the axis of the shaft above the horizontal line in all of our cases. The treatment consisted of closed reduction under general anaesthesia followed by a Dujarier's bandage for three weeks. Luxatio erecta is the commonest type of inferior dislocation. Its mechanism is a fall on the upper limb in great abduction or antepulsion. The clinical diagnosis is easy, confirmed by an anteroposterior radiograph. The functional long-term prognosis is excellent.
