Outcomes of Humerus Nonunion Surgery in Patients with Initial Operative Fracture Fixation.

This series of previously-operated aseptic humerus nonunions found that over one in five patients failed nonunion repair. De-novo post-operative infection and failure to perform revision internal fixation during nonunion surgery were associated with recalcitrant nonunion. Smoking and use of bone graft did not influence the success rate of nonunion surgery. These findings can be used to give patients a realistic expectation of results and complications following humerus nonunion surgery.
