Two-stage approach to obturator hip dislocation with subcapital femoral neck fracture: a case report

Anterior dislocation of the hip associated with an ipsilateral femoral neck fracture is exceedingly rare and typically results from high-energy trauma. We describe the case of a 33-year-old man who was engaged in a car crash and suffered numerous injuries, among them an anterior hip dislocation with the femoral neck trapped in the obturator foramen. The patient was treated in a single surgical procedure using a dual approach: resection of the femoral head through the Stoppa approach and placement of a primary total hip replacement through the Hardinge approach. The procedure was completed without complications, and rehabilitation included early mobilization with full weight-bearing at two weeks. At 24 months, the patient demonstrated preserved muscle strength, stable radiographs without loosening, and a Harris Hip Score of 86. This case highlights a rare injury pattern and supports the use of a dual-approach single-stage procedure as a safe and effective treatment strategy.
