Low-energy anterior hip dislocation in a dancer.

In this article, we report the case of a healthy young woman who sustained an anterior hip dislocation while participating in a noncontact activity (ballet dancing). The patient's atraumatic dislocation failed closed reduction secondary to interposition of anterior capsule and rectus femoris muscle. Open reduction using a Smith-Petersen approach was concentric and stable. Postinjury femoral nerve neuropraxia resolved within 6 weeks. At 2-year follow-up, the patient was without complications of the injury-including avascular necrosis and posttraumatic arthritis. She returned to dancing and is now asymptomatic.
