Functional long-term outcome of the shoulder after antegrade intramedullary nailing in humeral diaphyseal fractures.

Intramedullary nailing is one of the most commonly used surgical treatments for humeral diaphyseal fractures. Once an intramedullary fixation technique has been selected, the choice between antegrade or retrograde approach remains controversial. Forty patients with humeral diaphyseal fracture treated with Seidel antegrade intramedullary nailing through an "danterior deltoid incision" (ADI) were evaluated after an average period of 62 months.
