摘要:

文题释义:
足骨长度(SPCL):采用第二趾骨远端点与跟骨后凸中心点连线作为足骨水平中轴线,选取拇趾或二趾之中较长趾骨远端在中轴线上投影到跟骨后凸点之间的距离作为足骨长度。
拇外展角(HVA):拇趾的第一、二趾骨轴线夹角。第一趾骨轴线由远、近端关节面中点确定,第二趾骨轴线由骨干远端点及近端关节面中点确定。

背景:通过将传统X射线医学影像技术、数字化软件与解剖学结合,直观获取人体足部骨骼图像,可便于观察及测量足部各骨骼变化。当前国内外相关研究多集中于足部的病理状态、足底压力分布,有关人体在负重状态下的足部骨骼变化相关研究较少。
目的:探讨负重站立状态下足部骨骼变化。
方法:入选100例健康青壮年男性学生,采用中国刑事警察学院专项开发的足迹测量专用软件对X射线影像足部骨骼特征进行测量,记录正常状态与负重状态的人体足部骨骼相关数据。
结果与结论:①与正常站立状态相比,负重状态时足骨长度、跖区宽度、二五跖骨长度差显著性增加(P < 0.01);②与正常站立状态相比,负重状态时拇外展角、五趾内收角(小趾内翻)、一二跖骨长度差无显著性差异(P > 0.05),具有稳定性,可应用于医学足部骨骼关节测量研究及法医学检验鉴定;③负重前后拇外展角度改变用于区分轻度拇外翻患者及健康人群。

Abstract: BACKGROUND: Through the combination of traditional X-ray technology, digital software and anatomy, the visually obtained images of the human foot bones are easy to observe and measure the changes in the bones of the foot. At present, relevant domestic and foreign researches focus on pathological conditions of foot and plantar pressure distribution, and there are few studies on the changes of foot bones under weight-bearing conditions.  
OBJECTIVE: To explore the changes in the foot bones in the standing state.
METHODS: Totally 100 healthy young male students were selected. Special software developed by Criminal Investigation Police University of China for footprint measurement was used to measure the characteristics of the foot bones in the X-ray. Data of the human foot bones in normal and weight-bearing states were recorded.  
RESULTS AND CONCLUSION: (1) Compared with the normal standing state, the weight-bearing state had a significant increase in the foot bone length, width, and the difference in the length of the second and fifth metatarsal bones (P < 0.01). (2) Compared with the normal standing state, the weight-bearing state had no significant effect on the hallux abduction angle, the little toe varus angle, and the length difference between the first and second metatarsals (P > 0.05), with stability. It can be used in medical foot bone and joint measurement research and forensic examination and identification. (3) The change of hallux valgus angle before and after loading was used to distinguish mild hallux valgus patients from healthy people.

Key words: foot bone, hallux valgus angle, X-ray, digital technology, weight bearing standing
