Posterior Plating Versus Anterior to Posterior Screws in Fixation of Posterior Column in Pilon Fractures

The aim of this work is to assess and compare results of anterior to posterior screws versus posterior buttress plate in management of posterior column fracture in pilon fracture as regards functional, radiological outcomes and possible complications.

Optimal treatment of comminuted pilon fractures requires precise anatomical reduction. Several methods have been advocated to manage complex pilon fractures, but an optimal fixation technique remains controversial. On the basis of the anatomical characteristics of the ankle joint a four-column classification to guide the treatment of comminuted pilon fractures was proposed. The four-column classification can be summarized as follows: lateral column( the distal fibula), posterior column( the posterior part of the intermalleolus line with the distal tibial shaft), anterior column (the anterior part of the intermalleolus line with the distal tibial shaft) and medial column(the medial one-third of the tibial plafond with the distal tibial shaft).

A posterolateral incision is typically used to reduce and fix the posterior malleolar fragment to the tibial metaphysis which can be also done through the anterior incision using anterior to posterior screws.
