Is antegrade nailing a proper option in 2- and 3-part proximal humeral fractures?

Abstract

To report our experience with antegrade short locked intramedullary nail for treatment of proximal humeral fractures and to review the current literature. From January 2012 to July 2013, 41 patients affected by two and three-part proximal humeral fractures were treated with surgical internal fixation with short locked intramedullary nails. Outcome analysis included standard clinical follow-up, Constant shoulder score and plain radiographs. The mean follow-up was 30months (range 24-42). Moreover, a review of the literature was carried out. The mean Constant shoulder score was 81.5, excellent functional outcomes in 24/38 patients. All the fractures healed in an average time of 3.7months. Five patients underwent additional operations, complications included hardware penetration into the joint (n = 2), backed out screw (n = 1), shoulder impingement due to protrusion of the nail (n = 2) and superficial infection (n = 1). The literature review showed 530 patients affected by proximal humeral fracture and treated with intramedullary nail with mean age of 65years, mean follow-up of 22.2months and a Constant shoulder score of 72.9 points; the major complications reported were backing out of the screws, shoulder impingement and joint protrusion of the screws. Antegrade short locked intramedullary nail allows stable fixation, minimal soft tissue dissection, early mobilization of the shoulder and good outcomes. It is an efficacious therapeutic solution for 2- and 3-part proximal humeral fractures.
