The use of combined ۳.۵ LCP unicortical plate and nail fixation in proximal tibia fractures and prevention of valgus and anterior angulation

Introduction: Intramedullary nailing (IMN) of high tibia fracture has some mechanical and biological advantages over the other form of fixation. However, valgus, apex anterior malalignment and anterior displacement of proximal fragment commonly occur after isolated IMN fixation of proximal high tibia fracture. The purpose of this study is to determine the effectiveness of using ۳.۵-mm locking compression plate (LCP) with unicortical screws combined with IMN fixation to maintain the difficult reduction and prevent any displacement after classic nail insertion. Methods: This cross-sectional study was performed between ۲۰۱۰ and ۲۰۱۲, thirty-three open or closed tibia fractures involving the high proximal tibia metaphysis were operated using combined ۳.۵ mm LCP unicortical plate with the classic reamed intramedullary nailing technique. The clinical and radiological results of the study were collected on the basis of the time to ::::::::union::::::::, non::::::::union::::::::, mal::::::::union::::::::, degree of angulations at the fracture site, and infection. Follow-up ranged from ۲۴ to ۳۶ months (mean ۲۸ months). Results: The ::::::::union:::::::: rate was ۱۰۰% on radiographs at ۳.۳۸ months postoperatively. No complications such as mal::::::::union::::::::, delayed ::::::::union::::::::, implant failure, prominent valgus, anterior angulation malalignment, or postoperative deep infection occurred. Conclusions: Although prominent malalignment occurs after IM nailing of proximal one-third tibia fractures, we can avoid it by using the medially inserted ۳.۵ LCP unicortical plate. The results are good even in open fracture type one or two.
