Reduction Strategies Through the Anterolateral Exposure for Fixation of Type B and C Pilon Fractures

The surgical management of pilon fractures has evolved over the last several years with treatment shifting from acute definitive fixation to delayed fixation. One of the driving forces behind this change was the high incidence of soft tissue complications in those patients with high-energy pilon fractures (Orthopaedic Trauma Association 43B and 43C) managed with acute stabilization. Meticulous soft tissue handling along with delayed definitive fixation based on the soft tissue envelope has decreased the short-term complications associated with treatment of these injuries. Anterolateral exposure to the distal tibial articular surface allows for adequate visualization of most fracture patterns, novel reduction strategies, and successful implant placements. This exposure is useful in certain Type C pilon fractures, anterior and anterolateral Type B pilon fractures, and some extra-articular distal tibial fractures. The anterolateral exposure is not suitable in fractures with medial comminution, medial crush, impaction at the medial shoulder of the joint, segmental medial malleolar injuries, or varus deformity at the time of injury. The exposure has the advantage of excellent visualization of the articular surface up to the medial shoulder of the plafond while avoiding dissection of the anteromedial tibial surface.
