Treatment of Ipsilateral Distal Humerus and Diaphyseal Ulna Fractures by Using an Olecranon Osteotomy and Intramedullary Nail

Objective:To evaluate the results of treatment of an osteotomy of the olecranon and an ulnar diaphyseal fracture with a single nail, in cases with an ipsilateral ulnar diaphyseal fracture and a comminuted fracture of the distal humerus.Design:Retrospective clinical study.Setting:University-affiliated teaching hospital.Patients:Eight patients with comminuted fractures of the distal humerus and ipsilateral ulnar diaphyseal fractures were included.Intervention:Using a transolecranon approach, internal fixation of the distal humeral fracture with medial and lateral plates was performed. The ulnar diaphyseal fracture and additional osteotomy were fixed using a locked intramedullary nail. Subjective pain assessment was performed by using a visual analog scale (VAS).Results:There were 6 (75%) male and 2 (25%) female patients, with a mean age of 40.9 (range, 32-56) years. The mean follow-up period was 24.6 (range, 12-36) months. All patients achieved union of the ulnar diaphyseal fracture and olecranon osteotomy. Union of the distal humeral fracture was observed in 7 (87.5%) patients. The mean time to union was 16.3 (range, 12-22) weeks, mean visual analog scale score was 1.8 (range, 0-3), median elbow performance score was 85 (range, 70-95), and median disabilities of the arm, shoulder, and hand score was 17.9 (range, 5-45.8).Conclusions:Osteotomy of the olecranon and ulnar diaphyseal fracture using an intramedullary nail was a cosmetically advantageous and safe technique that enabled rehabilitation during the early postoperative period.Level of Evidence:Therapeutic Level IV.
