Does the Use of Locking Screws Decrease the Rate of Hardware Removal in Ankle Fractures

Background. While biomechanical characteristics of locking screw fixation versus traditional plating has been studied extensively in orthopaedic literature, clinical outcome studies are lacking. The goal of this study was to evaluate the efficacy and complications rate of locking versus traditional nonlocking screws in complex ankle fractures employing distal fibula internal fixation with 1/3 semitubular small fragment plates. Methods. A retrospective review was performed between January 2010 and June 2013 of all patients in whom internal fixation of the fibula in an ankle fracture (open or closed) was performed using only 1/3 semitubular small fragment fibular plates. Patient characteristics, fracture patterns, specific screw choice that were placed in the most distal 2 fibular plate holes (either locking or nonlocking), infectious wound complications, and concomitant syndesmotic injury and the need and corresponding purpose for hardware removal were recorded. Results. A total of 135 patients were found ...
