Abstract

We aimed to examine the clinical outcomes of proximal humeral fractures treated with different intramedullary nail shapes. Thirty-seven patients were divided into two groups depending on the implant shape. We also defined F group as a subgroup of fracture classification. In the F group, the flexion of the shoulder joint was significantly greater in S (mean, 134.6°) than in C groups (mean, 109°) (p = 0.04). The complication rate was significantly larger in the C group (p = 0.04). Patients with one kind of fracture and who were treated with straight nails had better outcomes.
