Hands-free Femoral Traction Using the Bookwalter Retractor System During Anterior Approaches to the Acetabulum

Displaced acetabular fractures with medial and cranial displacement of the femoral head commonly require an anterior approach for reduction and stabilization. Restoration of the femoral head to its native position under the reduced acetabular dome is a primary goal of surgery. We present a surgical technique for applying traction to the proximal femur using the Bookwalter retractor system during the repair of acetabular fractures when using an anterior approach. By placing traction in line with the femoral neck, the femoral head is moved to a more anatomical position allowing acetabular fracture fragments to be reduced unimpeded and the femoral head may be used as a reconstructive template. We review a case series of 116 patients treated using this technique and report the short- and long-term radiographic and clinical results of treatment.
