[Percutaneous osteosynthesis in tibial pilon fractures. Does the surgical technique determine the final result?]. / Osteosíntesis percutánea en fracturas de pilón tibial, ¿condiciona la técnica quirúrgica el resultado final?

ABSTRACT

OBJECTIVE: To analyze the outcomes of distal tibia fractures with or without extension into the ankle joint, treated by percutaneous cannulated screws or locking plates. MATERIAL AND METHOD: A retrospective study was conducted on 107 patients treated between 2001 and 2012. INCLUSION CRITERIA fractures 43-A and 43-C1 and C2 according to the AO/OTA system, treated with percutaneous osteosynthesis by locking plate or two cannulated screws in X -letter setting. A total of 33 patients were evaluated 16 tibial fractures were performed with locking plate (G1) and 17 with cannulated screws (G2). Mean time to surgery was 8.31 days (0-14) in G1, and 2 days (0-7) in G2. The mean follow-up was 72 months (12-132). Mean time to healing 17.08 weeks (8-48) in G1, and 14.56 weeks (8-24) in G2. The results were evaluated according to the AOFAS scale, with plain X-rays, and complications during follow-up. RESULTS: The mean evaluation according to the AOFAS score was 78.62 in G1 (22-93), and 90.63 in G2 (70-100), and this was statistically significant. In G1, 61.4% (8) of the results were excellent or good, while in G2 it was 76% (13). There were no axial deformity cases or shortenings. There were 4 superficial infections and one broken device recorded in G1. DISCUSSION: The percutaneous cannulated screw fixation is a suitable alternative for the management of fractures without significant joint involvement, and seems to offer better functional results than plates. The shortest time from injury to intervention in this group improves the progress of the soft tissues, and can improve the final result.
