BACKGROUND The aim of this study was to evaluate variables that could be related to complications and sequelae in fractures of the tibial pilon treated by open reduction and internal fixation (ORIF) with a locking compression plate-less invasive stabilising system (LCP-LISS). PATIENTS AND METHODS A total of 137 fractures treated by ORIF in a 7-year period were analysed. The mean follow-up was 3.3 years. We analysed the following variables: age, sex, side, type of fracture, energy of the injury, use of provisional external fixation (EF), time until ORIF, stages of treatment (one or two), surgical approach, type of bone fixation, quality of reduction, use of bone graft, hardware removal, associated fractures (fibula and others), functional results (AOFAS scale), early complications (infection, skin necrosis) and late complications (nonunion, early post-traumatic ankle osteoarthritis [AOA]). RESULTS According to the AOFAS scale, 30.5% of the results were excellent, 46.7% good, 13.1% fair and 9.7% poor. The rate of infection was 8.7%, and the rate of skin necrosis requiring flap coverage was 15.2%. Furthermore, type 43C3 fractures of the AO classification had a higher rate of skin necrosis and flap coverage. The rate of nonunion was 16.3% (22 cases, 4 aseptic, 18 infected), and the use of a medial plate was related to a higher rate of nonunion than the use of a lateral plate. The rate of early post-traumatic AOA was 13.1%, and open fractures were related to a higher prevalence of nonunion and flap coverage. Both infection and a suboptimal anatomic reduction were related to a higher prevalence of fair and poor results. The anteromedial approach was associated with a higher prevalence of skin necrosis and early post-traumatic AOA than the anterolateral approach. CONCLUSION Optimal reduction and stable fixation is paramount to diminishing the rate of complications and sequelae after ORIF (LCP-LISS) of these fractures.
