Because of the relatively large surface area of metaphyseal cancellous bone, the majority of distal femur fractures heal reliably. Nonunions of the distal femur do rarely occur, however, and the associated bone loss and soft tissue scarring can make successful treatment difficult. Few reports in the literature exist regarding the clinical and functional outcome after treatment of distal femoral nonunions. The purpose of this study was to evaluate the outcome of patients who underwent treatment of a distal femoral nonunion using a standardized treatment plan that included open reduction, internal fixation, supplemental bone graft, lag screw placement, and arthrolysis.
