Obturator dislocation of the hip in adults: Two cases

Abstract

Obturator hip dislocation is a rare variety of hip dislocation in which the femoral head is in front of the obturator foramen. It is caused by a violent accident. Obturator hip dislocation is rarely isolated. It is often associated with acetabular, femoral head or femoral neck fracture. The most feared complication is the femoral head necrosis. That is why an urgent reduction is required. We report two cases of Obturator hip dislocation. The first one is associated with a great trochanter fracture in a 48 years old patient. The second one is an isolated Obturator hip dislocation without any lesion of acetabulum or femoral head or trochanteric mass. In emergency, both had an urgent reduction of the dislocation with general anaesthesia, then transcondylar traction was made. In the first case, the great trochanter fracture has been synthesized by screwed hook plate. The two patient resumed work after three months. At the last review, there was no sign of femoral head necrosis.
