The present study investigated the clinical results of internal fixation of proximal humeral fractures using the Polarus humeral nail. Between September 2004 and September 2009, 34 shoulders of 34 patients (25 females, 9 males) underwent intramedullary fixation using the Polarus humeral nail. The mean patient age was 67 years, and the average period of follow-up was 27 months (range 12-77 months). According to the AO classification, 19 fractures were type A, 11 were type B, 2 were type C, and 2 were unclassifiable. We checked the radiographic results, JOA score and the range of shoulder motion,and investigated the relationships between these parameters and the incidence of complications. Bone union was obtained in 33 shoulders. Arthrotic changes were seen in 2 shoulders, but these did not worsen the clinical outcome. The average JOA score was 81 points(45-100). The average range of shoulder motion was 136 degrees for flexion, 39 degrees for external rotation, and L2 for internal rotation. Complications included infection, screw back-out, varus deformity, and osteonecrosis. Although the clinical and radiological outcomes of proximal humeral fractures after repair with the Polarus humeral nail were mostly satisfactory, it is important to prevent any potentially deleterious complications.
