ObjectiveTo assess variables that could be related to outcomes in fractures of the tibial pilon treated by open reduction and internal fixation (ORIF).DesignRetrospective.SettingUniversity Hospital.PatientsA total 92 fractures of the tibial pilon treated by ORIF in a 5-year period. The minimum follow-up was 1 year (mean: 3.3 years; range: 1-5).InterventionORIF with LCP-LISS plate.Primary Outcome MeasurementsAge, sex, side, type of fracture, energy of the injury, provisional external fixation (EF), time until ORIF, stages of treatment (one or two), surgical approach, type of bone fixation, quality of reduction, bone graft, hardware removal, associated fractures (fibula and others), functional results (AOFAS scale), rates of infection, skin necrosis, flap coverage, non-union, and early posttraumatic ankle osteoarthritis (AOA).ResultsAccording to AOFAS scale 30.5% of results were excellent, 46.7% good, 13.1% fair and 9.7% poor. Overall, the rate of infection was 13.04%, The rate of non-union was 10.86%. The rate of skin necrosis was 7.6% and the rate of flap coverage was 13.04%. The rate of early posttraumatic AOA was 13.04%. Type 43C3 fractures of the AO classification had a higher rate of skin necrosis and flap coverage. Open fractures were related to a higher prevalence of nonunion and flap coverage. The use of a bone graft was associated with a higher rate of nonunion and poor results. Infection was related to a higher prevalence of fair and poor results. EF was associated with a higher need for flap coverage. A suboptimal anatomic reduction was related to a higher rate of fair and poor results. The anteromedial approach was associated with a higher prevalence of skin necrosis and early posttraumatic AOA than the anterolateral approach. The use of an medial plate was related to a higher rate of nonunion than the use of a lateral plate.ConclusionsThe anteromedial approach was associated with a higher rate of skin necrosis and posttraumatic AOA than the anterolateral approach. Medial plating had a higher prevalence of nonunion than lateral plating.Level Of EvidenceIV (case series).
