Introduction: Twenty-four proximal humeral fractures were treated by surgical internal fixation with locked antegrade intramedullary nail. The purpose of this paper was to assess the clinical outcomes after treatment with antegrade humeral nail inplanted with an interval rotator split.

Material and Methods: We present a consecutive series of 24 patients with proximal and diaphyseal humeral fractures treated with the Telegraph^® nail inserted trough the interval rotators.

There were six proximal, seven bifocal interesting the third proximal and shaft and eleven diaphyseal humeral fractures fracture.

Results: The mean follow-up was 22 months with a range from 12 to 32 months, nineteen of the 24 patients were available for follow-up. All but two fractures progressed to healing. The mean Constant score were 80, Relative Constant score were 94,6%.

Conclusion: Intramedullary antegrade nail insert trough the interval rotator without violating rotator cuff results in good clinical outcomes and with certain fracture types can be an effective and satisfactory device.
