- We report the good results of two stage treatment in split depression type pilon fractures. A retrospective study of 9 cases among the 12 cases of split depression type pilon fractures from January 2009 to December 2015, who underwent two stage treatment of pilon fractures with minimum 24 months follow-up. And mean follow-up periods are 29 (24-41) months. In the first stage of the operation, reduction of articular surface using minial incision and external fixation were performed. As soft tissue heals, locking compression plate fixation was done with MIPO (Minimally Invasive Plate Osteosynthesis) technique. Radiographic evaluation was graded by the criteria of Burwell and Charnley. And functional assessment of ankle were evaluated by American Orthopaedic Foot and Ankle Society ankle-hindfoot score. Fractures were united in all cases within 17(12-24) weeks. Radiologic results were showed anatomical reduction in 8 cases and the mean AOFAS score is 87.8 (80-96). The mean range of ankle motion is 44 degree. There are one superficial wound complications and 3 cases of ankle osteoarthritis. Two stage treatment of split depression type pilon fractures is one of the good treatment methods, because of definitive second stage operation is more easier after first stage opertation designed to get early anatomical reduction, and shows good radiological and clinical outcomes.
