Obturator hip dislocation associated with contralateral luxatio erecta humeri: An unusual traumatic association (case report).

INTRODUCTION AND IMPORTANCE: Obturator hip dislocation and luxatio erecta humeri are two extremely rare injuries. We are reporting a very rare case that involves the association of these two injuries.

CASE PRESENTATION: We reported the case of a 34-year-old male who was a victim of a high-energy road accident. Initial examinations showed a right obturator dislocation associated with a left luxatio erecta humeri without vascular-nervous complication. Further examinations have ruled out life-threatening injuries. A closed reduction for both joints has been performed under general anesthesia less than 6 h following the trauma. Postoperative examination showed two congruent joints. Functional treatment has been implemented. Weight-bearing was permitted after 6 weeks, and physical rehabilitation of the shoulder was initiated 3 weeks after the trauma. Last examination (20 months after trauma) showed a painless two-joint with a full range of motion. There was no sign of shoulder instability, and radiographs showed no signs of avascular necrosis of the femoral head.

CLINICAL DISCUSSION: Both injuries are two rare orthopedic emergencies that require prompt diagnosis and immediate reductions.

CONCLUSIONS: A good outcome can be expected if functional treatment is applied after prompt closed reduction. Hence, regular monitoring is required to detect complications such as avascular necrosis of the femoral head for the hip and signs of instability for the shoulder.
