Bilateral Acromioclavicular Joint Subluxation in an Adolescent with Ehlers-Danlos Syndrome: Case Report and Literature Review

Abstract

Bilateral acromioclavicular joint (ACJ) dislocation is a rare occurrence, with only one reported case in the literature published in 1984. We present the case of a 15-year-old male with Ehlers-Danlos syndrome (EDS) who presented with complaints of subsequent nontraumatic bilateral ACJ subluxations and pain. ACJ reconstruction via an open mini-Mumford procedure was performed on this patient on two separate occasions with successful outcomes. The patient demonstrated decreased pain and increased stability during the postoperative period. EDS is a rare collagen disorder that is usually characterized by abnormal skin elasticity, bleeding tendencies, and, most importantly for this case, joint hypermobility. It is important to have an elevated index of clinical suspicion for potential joint subluxations and injuries in patients with a known history of collagen disease.
