Despite of improvements in internal fixation techniques and fixation materials used, distal humerus nonunions were observed. In osteoporotic fractures, and comminuted fractures, non-unions were observed in conditions when fixation was not performed according to fixation principles. In distal humerus non-unions; infection, bone reserve, incision scars due to previous surgeries, circulation and neurological evaluations must be held preoperatively. Good results can be achieved in distal humerus non-unions after debridement, correction of the alignment, grafting, capsular release, and rigid internal fixation.
