Use of an Intraoperative Limb Positioner for Adjustable Distraction in Acetabulum Fractures with Femoral Head Protrusion: A Case Report.

CASE Anatomic reduction of acetabular fractures with femoral head protrusion requires lateralization of the medialized femoral head to facilitate reduction and definitive fixation. In this case of a 71-year-old man with an associated both column acetabular fracture with femoral head medialization after a fall from a 10 foot ladder, we present the successful use of a novel reduction technique involving a modified arthroscopic limb positioner to provide adjustable distraction and counteract the deforming force in this injury pattern. CONCLUSION A limb positioner can provide appropriate on-table traction in pelvis and acetabular surgery to neutralize deforming forces and facilitate reduction and fixation.
