    Abstract:
    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 to meet inclusion criteria and were analyzed for this study. Of the patients with locking screws, 25 of 98 (25%) elected to have hardware removed, while 13 of 37 (35%) of those with nonlocking screws elected hardware removal. This did not reach statistical significance (P = .30). There was no statistically significant difference between the groups with regards to age, smoking status, body mass index, diabetes, or use of syndesmotic screw fixation. There was no significant difference in loss of fixation, infection, or other surgical complications in between the groups. Conclusions. There was no significant decrease in the rate of hardware removal with the use of 1/3 tubular locking versus nonlocking plates in the treatment of distal fibula fractures. Despite these screws locking flush to the plate, the hardware is equally symptomatic in both groups. There was no significant difference in the rate of complications between the 2 groups and our data suggest that the added expense of using locking screws routinely when fixing lateral malleolar fractures should be carefully considered, especially if the fracture pattern does not warrant locking technology. Levels of Evidence: Prognostic, Level III.
