【摘要】：目的研究穿着高跟鞋时前足跖间组织的应力变化,为跖间神经瘤诱发机制的定量分析和相应治疗方案提供参考。方法通过已验证的足-踝-高跟鞋有限元模型平台,分析足部在0、2.54、5.08、7.62 cm[0、1、2、3″(英寸)]4种不同跟高高跟鞋平衡站立以及穿5.08 cm跟高高跟鞋行走时步态周期内的跖间组织应力大小及趋势。结果随着鞋跟高度的增加,跖间组织应力明显增加,穿7.62 cm跟高高跟鞋时第3、4跖间组织受力是穿平跟鞋的312%。穿5.08 cm跟高高跟鞋行走时,在蹬地期第3、4跖间组织的受力最大,达到90 k Pa,与临床最常见的跖间神经瘤发病部位相符。结论穿着高跟鞋明显增加跖间组织的应力,鞋面横向挤压导致第3、4跖间组织受力最大,最容易导致跖间神经瘤的发生。
[Abstract]:Objective to study the stress changes of forefoot and metatarsal tissue in high heels. Methods through the verified finite element model platform of foot-malleole-high-heeled shoes, we analyzed the foot at 02.54% 5.08. The results provided a reference for the quantitative analysis of the inducing mechanism of interplantar neuroma and the corresponding treatment plan. 7.62 cm. [0,1,2. 3 "(in)] 4 kinds of heel high heels balanced standing and walking with 5.08 cm high heels during gait cycle, the stress size and trend of plantar tissue were observed. The results were as follows: the heel height increased. The stress of intermetatarsal tissue was obviously increased. The stress between the third and fourth metatarsal tissue was 312cm in flat heels when wearing 7.62 cm high heels, and the third time in pedal stage when walking with 5.08 cm high heels. (4) the stress of plantar tissue was the largest, reaching 90 kPA, which was consistent with the most common clinical site of intermetatarsal neuroma. Conclusion wearing high heels significantly increased the stress of plantar tissue, and the lateral extrusion of the upper of the shoe resulted in the third. 4 the intermetatarsal tissue has the greatest force and is the most likely to cause the occurrence of intermetatarsal neuroma.

【正文快照】： 当今都市社会,高跟鞋已成为女性必不可少的时尚装备,然而穿着高跟鞋所引起的跖间神经瘤已成为女性足部的常见疾病之一,极大危害了女性足部健康[1-2]。Thomson等[3]报道,中年女性跖间神经瘤的发病率较中年男性甚至超过10倍[3]。早在1876年有关跖间神经瘤疾病的临床表现就已有报
