Obturator hip dislocation with intrapelvic migration of the femoral head in Ehlers–Danlos syndrome

Excerpt

Hypermobility of the joints is a cardinal feature of Ehlers–Danlos syndrome (EDS) and joint dislocation as a result of no or minor trauma, is a relatively frequent complication of any form, because of ligamentous laxity [1‐3]. Hip dislocations are usually the result of high-energy trauma in young adults, with most being posterior [4‐6]. Obturator hip dislocations are relatively rare injuries, accounting for no more than 7% of all traumatic hip dislocations [6, 7]. No obturator hip dislocation as a result of minor insult in EDS has yet been reported. We report an unusual case of obturator hip dislocation by minor insult in EDS, complicated by femoral neck fracture and intrapelvic migration of the femoral head occurring during closed reduction, and also suggest management relevant to this rare injury. …
