Review Clinical Trial[Angle-stable intramedullary nailing of proximal humerus fractures with the PHN (proximal humeral nail)].
Stable fixation of two- and three-part fractures of the proximal humerus through minimally invasive operative technique and rapid bone healing as well as restoration of original anatomy. Early functional training with the goal of restoration of former mobility and daily activities. ⋯ 151 proximal humeral fractures were treated with a proximal humeral nail (PHN). 108 patients could be followed up 1 year postoperatively. Significant complications were perforation of the articular surface through bolts or blades (n = 8), implant-related pain (n = 10), fragment dislocation (n = 2), nonunion (n = 2), humeral head necrosis (n = 3), and superficial infection (n = 1). 1 year after the operation, the Constant-Murley Score showed a median value of 75.3 in the injured shoulder and of 89.9 in the uninjured shoulder. The DASH (Disability of the Arm, Shoulder and Hand) Score was 5.9 preoperatively and 9.3 at 1 year postoperatively. The worst results regarding the Constant-Murley Score as well as the DASH Score were found in C-type fractures.
