【摘要】：背景:拇外翻具有较复杂的足部解剖畸形,使足底区域的压力发生改变。目的:分析拇外翻的发病危险因素,检测拇外翻患者平地自然行走下足底压力分布特征。方法:采用比利时RSscan INTERNATIONAL公司生产的footscanU SB2平板式足底压力测试系统,检测50例拇外翻患者和年龄、身高、体质量匹配的30例正常人的动态足底压力。所有受试者测试时均脱鞋袜,以个人平常步态自然行走,每人测试3次以上,取得动态足底压力曲线及特征量参数,对曲线及各参数进行分析。结果与结论:(1)测试的拇外翻患者中,女性占94%(均穿高跟尖头鞋),男性占6%(均不穿高跟尖头鞋),96%有遗传史;(2)在自然行走步态中,拇外翻患者双足第1跖骨区压力明显增高,与正常人足底压力图形明显不同;(3)拇外翻患者第1跖骨的平均压力峰值、平均负荷值、平均冲量与正常人相比,均明显增高(P0.05或P0.01)。(4)结果说明,除遗传因素外穿高跟尖头鞋是拇外翻发生的一个重要因素,拇外翻患者第1跖骨区压力、负荷、冲量明显增高,促使了拇外翻的发生发展。通过分析拇外翻的发病危险因素以及拇外翻患者动态足底压力情况,可以为拇外翻的预防、治疗、功能康复等提供重要参考。
[Abstract]:Background: hallux valgus has complex anatomic deformity of foot, which changes the pressure of plantar region. Objective: to analyze the risk factors of hallux valgus. The characteristics of plantar pressure distribution in patients with hallux valgus were measured. Methods: 50 patients with hallux valgus, age and height were measured by footscanU SB2 flat plantar pressure test system, which was produced by RSscan INTERNATIONAL Company in Belgium. The dynamic plantar pressure of 30 normal subjects matched with body mass. All subjects took off their shoes and socks and walked naturally in their normal gait. The dynamic plantar pressure curve and characteristic parameters were obtained. Results and conclusions among the patients with hallux valgus tested by 1: 1, 94 women (all wearing high-heel shoes and six men) had a genetic history of walking in their walking gait. The pressure of the first metatarsal area in the patients with hallux valgus was significantly higher than that in the normal subjects (P < 0.05). The mean pressure peak value, mean load value and mean impulse of the first metatarsal bone in the patients with hallux valgus were significantly different from those in the normal subjects. The results showed that wearing high heel shoes was an important factor in the occurrence of hallux valgus except for genetic factors. The pressure, load and impulse of the first metatarsal area in the patients with hallux valgus were significantly increased. By analyzing the risk factors of hallux valgus and the dynamic plantar pressure in the patients with hallux valgus, we can provide important reference for the prevention, treatment and functional rehabilitation of hallux valgus.
