Olecranon tension plating or olecranon tension band wiring? A comparative biomechanical study

Purpose The complication rate of a tension band wiring (TBW) used for the internal fixation of olecranon fractures remains high. The aim of this study was to compare the stability of a novel olecranon tension plate (OTP) with TBW in a simulated fracture model. Methods We tested 12 fresh frozen-pairs...

Zusammenfassung:	Purpose The complication rate of a tension band wiring (TBW) used for the internal fixation of olecranon fractures remains high. The aim of this study was to compare the stability of a novel olecranon tension plate (OTP) with TBW in a simulated fracture model. Methods We tested 12 fresh frozen-pairs of cadaver proximal ulnae treated with OTP and TBW under cyclic loading. The elbow motion ranged from full extension to 90° of flexion, and the pulling force of the triceps tendon ranged from 50 to 350 N. The displacement of the fracture fragments was measured continuously. Data were assessed statistically using the Wilcoxon test with significance level of p
