【 摘 要 】

BackgroundTension band wiring (TBW) is a common surgical intervention for olecranon fractures. However, high rate of complications such as loss of reduction, skin irritation, and migration of the K-wires were reported up to 80%. Ding’s screw tension band wiring (DSTBW) is a new TBW technique that has shown positive results in the treatment of other fracture types. The objective of this study was to evaluate the stability of DSTBW in the treatment of olecranon fractures by finite element analysis.MethodWe used Ding’s screw tension band fixation (DSTBW) and K-wire tension band fixation (TBW) to establish a finite element model to simulate and fix olecranon fractures. The stress distribution, opening angle, twisting angle, and pullout strength of K-wires or screws were analyzed and compared.ResultsThe maximum von Mises stress was observed on the internal fixation for 90° elbow motion in both groups. The von Mises value of the screw in DSTBW was 241.2 MPa, and the von Mises value of k-wire in TBW was 405.0 MPa. Opening angle: TBW was 0.730° and DSTBW was 0.741° at 45° flexion; TBW was 0.679° and DSTBW was 0.693° at 90° flexion. Twisting angle: TBW was 0.146° and DSTBW was 0.180° at 45° flexion; TBW was 0.111° and DSTBW was 0.134° at 90° flexion. The pullout strength of DSTBW was significantly higher than that of TBW. Maximum pullout strength of Ding’s screw was 2179.1 N, maximum pullout strength of K-wire was 263.6 N.ConclusionDSTBW technology provides stable fixation for olecranon fractures, reducing the risk of internal fixation migration and failure.
