Fourteen patients in whom open reduction and internal fixation could not be achieved satisfactorily had a total elbow arthroplasty for non-union of a supracondylar humeral fracture. All patients had an established non-union, and ten had had from one to four previous attempts at internal fixation. The average age at the time of operation was sixty-five years. The average duration of follow-up was five years, with a minimum of two years. The average preoperative elbow score was 17 points, with both pain and functional disability present. The average postoperative score was 84 points; there were eight good or excellent results and three failures. The latter three patients had an additional operation: one each for dislocation, loosening of the humeral component, and deep infection. Salvage of supracondylar non-union by means of a total elbow arthroplasty is a technically demanding procedure. Strict indications for selection of patients must be followed. A semiconstrained implant is recommended, with preservation of the epicondyles and their muscular attachments in order to achieve balance of the soft tissues.
