Bilateral cases are even less frequent, with only eight cases reported in the literature. Method and result. We report one case of bilateral inferior dislocation of the shoulder. The patient made a complete functional recovery within 2 years after treatment by closed reduction and rehabilitation. Conclusion. Based on this case and the pertinent literature, the pathophysiology, diagnosis, and treatment of this rare injury are discussed.
