Exchange nailing and medial wall reconstruction following implant failure in a subtrochanteric femoral fracture

Abstract

Failure of fixation of subtrochanteric fractures has been reported in as high as 20% of cases. Several associations have been suggested to contribute to failed fixation. Discontinuity of the medial wall/column is considered to be one of the most significant risk factors for non-union and subsequent implant failure, especially if this defect is not addressed during the revision surgery. We present a case of failed fixation of a subtrochanteric fracture in an 86-year-old female where revision surgery paid special attention to restoring the medial wall continuity via bone grafting resulting in satisfactory union of the fracture. We advocate the necessity of reconstructing the medial column in similar cases in order to enhance healing and restore the biomechanical support of the subtrochanteric region.
