Case report: Pure obturator dislocation of the hip, a rare variety of regular dislocations, and long-term clinical outcomes

Abstract

Post-traumatic dislocation of the hip is a surgical emergency that is usually caused by a high-energy trauma in a context of polytrauma. The pure obturator hip dislocation variant is very rare. It is considered an emergency, and its management must be done within 6 h by a qualified surgeon in order to reduce the risk of osteonecrosis of the femoral head and iatrogenic fractures. Herein, we report the case of a pure obturator dislocation of the hip, following a high-energy trauma. The patient was treated urgently by closed reduction under general anesthesia. The functional and radiological results after 2 years were satisfactory, without signs of avascular necrosis.
