Posterior Arthroscopic Reduction and Internal Fixation for Treatment of Posterior Malleolus Fractures.

Posterior malleolus fractures and pilon variants refer to a pattern of fractures involving the posterior weightbearing surface of the tibial plafond. The surgical indications for fixation of posterior malleolus fractures varies considerably throughout the literature, based on the size and/or displacement. There is controversy on how to best address fracture fixation, with the main workhorses being either the posterior-lateral approach or indirect anterior-posterior-directed screws. We present an alternative technique for posterior malleolus fracture fixation using a direct posterior arthroscopic-assisted reduction internal fixation method. With this method, posterior malleolus fractures are reduced arthroscopically and percutaneous fixation is placed through the arthroscopic portals. Level of Evidence: Level V, expert opinion.
