ABSTRACT Objective Double plate (DP) fixation does not significantly improve outcomes compared to lateral locking plate (LLP‐only) fixation for distal femur fractures (DFFs). We hypothesize this is due to the absence of clear indications for the application of these two fixation methods. This study...
