Inferior glenohumeral dislocation (luxatio erecta humeri): report of six cases and review of the literature.

BACKGROUND Inferior shoulder dislocation, also referred to as luxatio erecta, is a rare type of shoulder dislocation. Its incidence is about 1 in 200 (0.5%) among all shoulder dislocations. The objective of this study was to review six cases of inferior shoulder dislocation, including their clinical and radiological presentation, management, and final outcome. METHODS Four males and two females, a total of six patients, with the diagnosis of inferior shoulder dislocation were treated between 2007 and 2010. Our purpose is to present our experience in the treatment of these patients together with the parallel research available in the literature. RESULTS Constant score was used to evaluate shoulder function. Pain, position, daily activities, range of motion, and strength scores were noted. All patients had good to excellent results with full functional recovery within two years after closed reduction and shoulder rehabilitation. CONCLUSION Doctors should be familiar with the occurrence of this infrequent condition and should prevent possible complications that might result from early reductions by using correct maneuvers in lieu of ordinary reduction techniques.
