Traumatic obturator dislocation of the hip associated with ipsilateral subtrochanteric femur fracture in a young adult: a case report

Introduction: Traumatic obturator-type anterior dislocation of the hip with an ipsilateral subtrochanteric fracture is rarely encountered in clinical practice. This case presentation described a trauma patient with such a rare scenario.

Case report: This paper reports a case of a 20-year-old Amhara ethnic male patient who had a traumatic anterior dislocation of the hip associated with an ipsilateral subtrochanteric femur fracture after a truck rolled over. There was diffuse swelling of the proximal thigh, and the lower limb was externally rotated. Radiographic examination shows right femur subtrochanteric fracture with ipsilateral obturator-type anterior hip dislocation. Emergency open reduction of the hip dislocation and antegrade intramedullary nailing of the subtrochanteric fracture performed. Subsequent clinical and radiologic follow-up demonstrated good outcomes.

Conclusion: The main peculiarity of the presented case is the association of obturator hip dislocation with ipsilateral femur shaft fracture. Early and stable reduction of the dislocation and firm internal fixation of the fracture as soon as possible will allow early rehabilitation and prevent late complications. At the 4th week of operation, he started non-weight-bearing mobilization.
