Open reduction and internal fixation of delayed union and nonunion of the distal humerus.

Abstract

Nonunion of a condylar fracture of the distal humerus rarely occurs, but when present it is difficult to manage. We recommend internal fixation of the nonunion in combination with decortication and autogenous iliac crest bone grafting along with careful selection and placement of the implant. Postoperatively, the goal is preservation of elbow motion until the nonunion heals. We reviewed the cases of five patients who had surgery for nonunion of this fracture, all of which healed within 2-3 months after surgery. At final follow-up their average arc of motion was 88 degrees.
