Biomechanische Untersuchung der winkelstabilen Plattenosteosynthese am proximalen Humerus

Abstract

The NCB-PH plate provides superior interfragmentary stability when used in the locked mode in a human cadaveric proximal humerus fracture model. Therefore, we recommend that all screws should be inserted in the locked mode. The results suggest that the NCB-PH plate in the locked mode provides higher primary postoperative stability thus permitting early functional treatment of the patient.

Monoaxial versus polyaxial locking systems: a biomechanical analysis of different locking systems for the fixation of proximal humeral fractures

“…The design, together with the locking mechanism, allows implantation of this plate fixator as a hybrid system [2]. Screws may be inserted as lag screws, may be used for compression and indirect reduction and may anytime during the operation be locked at a fixed angle [13]. These advantages, in comparison to the head locking screws, are at the expense of thicker plates and fewer screws in the head fragment.…”
