Use of Angle-Stable Implants for Proximal Humeral Fractures: Prospective Study

PURPOSE OF THE STUDYTo evaluate and compare proximal humeral fractures treated either by plate osteosynthesis with angular-stable screws or by intramedullary nailing, and to define the indications optimal for use of either technique. MATERIALThe study comprised 97 patients.The proximal humeral internal locking system (PHILOS) plate was used in 49 patients (31 women and 18 men); with age average 57.4 years (women, 64.5 and men, 45.3 years).By the AO classification, 12 patients with type A, 15 with type B, and 22 with type C fractures.The Targon PH nail was used in 48 patients (32 women and 16 men) at an average age of 65.3 years (women, 72.2 and men, 51.4 years).Type A fractures were in 18, type B in 18 and type C in 12 patients.
