Abstract

Traumatic anterior dislocation of the hip is rare. Bilateral traumatic anterior dislocation is an even rarer injury; indeed, only 5 cases have been reported in the English literature. We describe a case of a bilateral traumatic anterior dislocation of the hip and a concomitant unstable lumbar burst fracture following a mechanism of injury distinctly different from other reports.

Figure

• 

  Fig. 1 Radiograph showed bilateral anterior dislocation of both hip joints and disruption of the axial alignment at L4/5.

• 

  Fig. 2 Radiograph showed concentric reduction of both hips

• 

  Fig. 3 Radiograph showed axial malalignment and decreased vertebral body height of L5.

• 

  Fig. 4 Pelvis computed tomography showed extra-articular fracture of the right acetabulum (A), sacral alar (B), and anterior portion of the sacroiliac joint on the left (C).

• 

  Fig. 5 Computed tomography showed an unstable burst fracture of L5. Fracture of the L5 body with a greenstick lamina fracture (A) and bilateral inferior articular process fracture of L4 (B).

• 

  Fig. 6 Postoperative radiographs showed posterior segmental fixation from L3 to S1.
