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.

Irreducible Posterior Hip Dislocation with Associated Isolated Comminuted Greater Trochanter Avulsion Fracture Treated with Universal Locking Trochanteric Stabilization Plate: A Rare Combination of Hip Injury

“…In other series, Selvanayagam and Vivek fixed greater trochanteric fracture with 6.5 mm screw fixation in his case report and produce full range of hip motion without any evidence of osteonecrosis or osteoarthritis at one year follow up [16] [17]. Concha et al reported a case of obturator type hip dislocation with greater trochanteric avulsion fracture treated successfully with tension band wiring and produce Harris Hip Score of 89 at 1-year postoperative period [18]. Akash and Subawa in their series of anterior hip dislocation with greater trochanteric avulsion utilised proximal femoral plate for fixation and achieved satisfactory outcome at 4 months' postoperative period using Modified Merle d'Aubigne Score and Oxford Hip Score.…”
