ABSTRACT

Dislocation erecta humerus (dislocation of the shoulder), a rare variety of lower dislocation of the shoulder, represents 0.5% of the total dislocations described in 1859 by Middeldorp, especially in young subjects. It is remarkable for its spectacular clinical deformity (arm in the air in forced abduction with impossibility of bringing back the elbow to the body) is often complicated by fractures of the trochiter or the lower edge of the glenoid. We report 19 cases of erecta shoulder dislocations collected between 2008 and 2018. There are fourteen men and five middle-aged women (23 years old), the right shoulder was dislocated in fourteen cases, and the mechanism was direct in nine patients. No disturbance of the vascular system was observed. The radiograph of the shoulder in front of the patient showed a lower dislocation of the humeral head and a diaphyseal axis above the horizontal in all our observations. The treatment consisted of a reduction under general anesthesia followed by a Dujarier dressing for three weeks. Dislocation of the erecta-type shoulder is the typical form of inferior dislocation; its mechanism is a fall on the upper limb in great abduction or antepulsion. The clinical diagnosis is easy, confirmed by the X-ray of the shoulder. The long-term functional prognosis is excellent.
