Objective The purpose of this study was to evaluate the results of open reduction and internal fixation of nonunions of the surgical neck of the humerus.

Design Retrospective review of patients who underwent operative treatment of a surgical neck of the humerus nonunion.

Setting Shoulder and elbow service at two university centers.

Patients Thirteen patients with a two-part nonunion of the surgical neck of the humerus who were treated with open reduction and internal fixation with bone graft with a minimum of 12 months' follow-up were included. Patients with avascular necrosis, posttraumatic arthritis, severe humeral head bone loss, or a nonunion of one of the two tuberosities were excluded.

Intervention Open reduction and internal fixation with either a blade plate or a T-plate and autogenous bone graft.

Main Outcome Measures Medical records, operative reports, physical examination, and preoperative and postoperative radiographs were reviewed. Outcome was assessed using Neer's criteria for the evaluation of total shoulder arthroplasty, visual analogue pain scale, range of motion, and ability to perform activities of daily living.

Results The results were excellent in 11 patients, satisfactory in 1 patient, and poor in 1 patient. The 11 nonunions in patients with excellent results healed within 6 months. The patient with the poor result initially had a persistent nonunion and required revision, open reduction and internal fixation, and bone grafting. This patient healed and went on to have an excellent result at final follow-up. All fractures were healed at the time of this study. Pain scores decreased from an average of 4.2 preoperatively to 1.2 postoperatively on a 5-point pain scale. Forward elevation in the scapular plane improved from 24° preoperatively to 144° postoperatively. All patients but one were able to attain overhead elevation. All patients were able to perform activities of daily living, such as dressing, bathing, combing hair, and performing perineal care, at final follow-up. Overall satisfaction increased from an average of 1.0 to 9.4 on a 10-point visual analogue scale.

Conclusions Open reduction and internal fixation with autogenous bone graft results in excellent outcomes even in patients >65 years old and patients with significant medical problems. This treatment method offers predictable fracture healing and has a low complication rate.
