Background: Olecranon fractures are common in motorcycle accidents, falls, or in direct elbow injury. In cases of transverse olecranon fracture, surgery is frequently required in adults. The aim of this study is to compare the biomechanical durability of suture anchor fixation in olecranon fractures to conventional tension band wiring technique in saw bones. Methods: 12 plastic saw bones were divided into 3 groups: tension band wiring fixation, modified Cha-Batman method, and a modified simple suture method using a suture anchor. After fixation, cyclic load tests were conducted for 1,000 cycles, at 5 Hz with a force of 10 N to 250 N. After cycling loading, the extent of displacement was measured using a non-contact coordinate measuring instrument, and statistical analysis performed. Results: The average displacement was significantly smaller in the modified Cha-Bateman method (1.4 mm) than in the tension band wiring method (3.8 mm, p = 0.007) and the modified simple suture method using suture anchor (3.3 mm, p = 0.012). There was no significant difference in displacement between tension band wiring fixation and the modified simple suture method (p = 0.564). Conclusions: This study provides a biomechanical basis for the hypothesis that the suture anchor technique in weak bone model could obtain results comparable to those of conventional tension band wiring. In particular, the modified Cha-Bateman method, showed stronger biomechanical properties than the tension band wiring method and modified simple suture method using a suture anchor. The current study could also provide pilot data that can be used in future experiments.
