Abstract

Background: The aim of study was to biomechanically compare the fixation of Jones fracture using headless cannulated screw, tension band, and two Kirschner wires.

Methods: A total of 60 fourth-generation, fifth metatarsal synthetic bone models were divided into three groups according to the fixation techniques. A vertical load, oriented from plantar to dorsal and lateral to medial, was applied to the metatarsal specimen that were potted with molding material. The stiffness and fatigue values were compared between the three fixation groups.

Results: In the plantar to dorsal load test, the stiffness values were found to be significantly higher in Group 1 compared to the other groups (P = .034, P = .013). No significant difference was found in the analysis in terms of fatigue values in plantar to dorsal load testing (P = .348, P = .416). No significant difference was found between compression screw and tension band groups in lateral to medial loading test, in terms of stiffness and fatigue values (P = .096, P = .762). However, the stiffness values and fatigue values of these two groups were found to be statistically significantly higher than the Kirschner wire group (P = .003, P = .002, P = .016, P = .023).

Conclusions: The result of this study showed that the bicortical fixation of headless compression screw provides a more stable fixation than other fixation methods, especially in plantar to dorsal loading.

双皮质无头空心螺钉固定、张力带固定和克氏针固定治疗琼斯骨折的生物力学研究。

背景：本研究的目的是比较无头空心螺钉、张力带和两根克氏针固定琼斯骨折的生物力学效果。方法：将60例第四代、第五代跖骨合成骨模型按固定方法分为3组。将垂直载荷，从足底到背侧，外侧到内侧，应用于用模塑材料填充的跖骨标本。比较三个固定组的刚度和疲劳值。结果：在足底至背部负荷试验中，组1的刚度值明显高于其他组（P = 0.034, P = 0.013）。在足底和背部负荷测试中，疲劳值的分析没有发现显著差异（P = .348, P = .416）。受压螺钉组和张力带组在侧、内侧载荷试验中刚度和疲劳值无显著差异（P = 0.096, P = 0.762）。但两组的刚度值和疲劳值均显著高于克氏针组（P = 0.003, P = 0.002, P = 0.016, P = 0.023）。结论：本研究结果表明，与其他固定方法相比，无头加压螺钉双皮质固定提供了更稳定的固定，特别是在足底到背侧负荷时。
