目的研究氟中毒对肘关节尺神经应力松弛的影响,为临床提供生物力学参数。方法复制氟中毒动物模型,取动物模型肘关节尺神经进行应力松弛实验。结果得出了对照组和实验组动物肘关节尺神经应力松弛数据和曲线。结论实验组肘关节尺神经7200S应力松弛量显著低于对照组,氟中毒对动物尺神经应力松弛特性有一定影响。 Objective To study the effect of fluorosis on the stress relaxation of ulnar nerve in elbow joint and to provide biomechanical parameters for clinic. Methods Fluorosis animal model was duplicated and the ulnar ulnar nerve of animal model was subjected to stress relaxation test. Results The stress relaxation data and curves of the ulnar ulnar nerve of the control group and the experimental group were obtained. Conclusion The 7200S stress relaxation of the ulnar ulnar nerve of experimental group was significantly lower than that of control group. Fluorosis had some effect on the stress relaxation of ulnar nerve in experimental group.
