目的：测量小夹板固定骨干骨折时骨干轴向牵引力。
方法：通过有机玻璃材料加工成类似哑铃形状模拟长骨两端膨大的特征，在模拟骨干骨折截断处串联安装力传感器；同时，采用布袋液压囊模拟肌肉等软组织，测量夹板固定时断端骨干轴向牵引力。
结果：轴向牵引力与横向夹板压力有正相关，产生的骨干轴向牵引力约为夹板横向加压力大小的1/10。
结论：筋膜包裹的肌肉与布袋液压囊力学作用类似，夹板在肢体侧面横向加压时，在骨折端可以产生骨干轴向牵引力。 |

| Analysis of the axial stretching force of the small splint fixation system |
|
Abstract:
Objective: To measure the axial stretching force produced by the small splint fixation system in the treatment of the fracture.
Methods: Dumbbell shaped plexiglass was machined to model the bone shaft with expanded two ends.Force transducer was set at the model fracture site to measure the stretching force produced by fracture fixation of the small splint with cloth aqueous bag that simulated the muscles and other soft tissue underneath.
Results: There was positive relationship between the axial stretching force produced at the model fracture site and the transverse pressing force exerted by the external plates.The ratio of which was 1/10.
Conclusion: Muscle enwrapped with fascia is similar to the cloth aqueous bag system in mechanical structure.From this article, axial stretching force exists at the bone shaft fracture site when fixed by small splint which exerts the force transversely from the outside of the extrimity. |
