Purpose: Our aim was to analyze the outcomes of our initial experience in the treatment of proximal humeral fractures. The present technique lies in the implantation of an intramedullary nail with a spiral blade and guided interlocking distal bolts.

Methods: The series consisted of 5 patients (mean age 43.2 years old). Proximal humeral fractures included AO/ASIF type 11-B2 (3 cases) and type 11-A3 (2 cases). Follow-up was 15.7 months, observing absolute bone healing in all cases.

Results: Mean range of motion was 120˚ (SD 12). The mean central score on the Constant scale was 85.60 points (69-100) on the affected side, compared to the 97.60 points (100-88) obtained in the healthy side. The age- and sex-adjusted Constant score was 86.70 (SD 13). The physical component of the SF-12 indicated a moderate impact on health-related quality of life.

Conclusion: Based on the favorable clinical and radiological outcome, the PHN nail appears to be an effective implant for attaining stability in displaced fractures, and this should be included as a possible form of treatment within the range of possible surgical repairs.
