Traumatic obturator–anterior type dislocation of the hip with an ipsilateral ischial tuberosity and greater trochanter fractures: Case report

Abstract

Anterior hip dislocation is a rare orthopedic emergency, usually following high-energy trauma. This injury is occasionally associated with acetabular fractures, femoral head fractures, or diaphyseal femoral fractures. However, the combination between the anterior hip dislocation and the ipsilateral ischial tuberosity and greater trochanter fractures is extremely rare, and very sparsely reported in the literature. This paper reports a case of an obturator type of anterior hip dislocation associated with a concomitant ipsilateral ischial tuberosity and greater trochanter fracture. The hip dislocation was reduced by closed means under general anesthesia, and the greater trochanter fracture was reduced and internally fixed with tension band in a second stage. Radiological and functional evaluation at 12 months after surgery, using the Harris Hip Score (HHS), was good.
