Abstract

Traumatic hip dislocation in children is relatively rare accounting for about 5% of all hip dislocations. Most of the hip dislocations seen in children are of the posterior type but the much rarer anterior and anterior-inferior (obturator) types have also been described. We present the case of an eight years old girl with an obturator type of hip dislocation following trivial trauma. She was treated with closed reduction and immobilisation in skin traction for three weeks. She was followed up closely for one year and did not develop any complications during that period.

Summary

INTRODUCTION

Traumatic hip dislocation in children is relatively a rare injury accounting for about 5% of all hip dislocations[1]. Revealed a hip dislocation with the femoral head lying inferior to the acetabulum, in the obturator foramen (Figure 1). On discharge from the hospital after three weeks, the patient had painless, full range movements of the left hip. She was discharged home with axillary crutches to allow weight bearing as tolerated. The patient was reviewed at three and six months She had a painless right hip and was ambulating unassisted full weight bearing. At one year follow-up, the patient had painless full-range movements in the right hip with no signs of AVN on plain radiographs as well as on magnetic resonance image (Figure 3)
