New anterolateral LCP for internal fixation of pilon fractures

Abstract

Objective To introduce experience of using the new AO anterolateral distal tibia locking com-pression plate (LCP) for treatment of Pilon fractures. Methods Between February and August of 2009,8 closed Pi-lon fractures were treated by open reduction and internal fixation. The distal fibula was fixed with a one-third tubular plate or an recontruction plate via a straight incision posterior to the fibular crest. The distal tibia was approched by a straight incision over the ankle joint, and the fracture was stabilized using an anterolateral distal tibia LCP. Regular follow up was made to observe and evaluate the preliminary clinical outcomes. Results Seven of the 8 patients were availabe for follow up for 3 ～ 6 months (average 4.5 months). All incisions obtained primary healing, though one ex-perienced mild superficial inflammation,and none developed deep infections. Based on the Burwell and Charnley radi-ographic criteria,anatomical reduction was obtained in 5 cases,good in 1 ,and fair in 1. Among the 5 cases exceeding 5 months postsurgery,4 were evaluated as excellent and 1 us good according to Tometta' s clinically based criteria for Pilon fractures. Conclusion With good surgical timing,internal fixation with anterolateral LCP for Pilon fractures is reliable and warrants less complications.
