Use of an Intraoperative Limb Positioner for Adjustable Distraction in Acetabulum Fractures with Femoral Head Protrusion

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.A limb positioner can provide appropriate on-table traction in pelvis and acetabular surgery to neutralize deforming forces and facilitate reduction and fixation.
