Ankle Joint

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

科学领域:

整形外科手术整形外科手术
医学成像医学成像
人体解剖学解剖学解剖学

背景情况:

关节整形术 (TAA) 解决了末期关节关节炎,但面临着当前假肢的局限性.
需要更好地匹配解剖特征的脚假肢.
这项研究为改善脚假肢设计提供了解剖基础.

研究的目的:

为了评估中国人口的脚形态测量数据.
为设计改进的全脚假肢建立一个解剖学基础.
为了确定脚关节的性别相关和侧面特定的解剖学差异.

主要方法:

利用了50个中国脚关节的CT扫描.
使用专门的软件 (模拟,3-matic,Hypermesh) 进行了3D重建和网联.
测量了27个解剖学脚关节参数,包括小腿板宽度 (TiW) 和DLA.

主要成果:

27组CT测量数据遵循正常分布.
在27项测量中,在18项测量中发现了与性别相关的显著差异,男性的尺寸更大.
观察到最小的双边不对称性,除了男性的中部背中维度 (MDV).

结论:

中国人口中的脚关节参数显示出与性别相关的差异和区域差异.
发现了双边不对称性,特别是在男性中.
假肢设计必须考虑性别,种族和侧面特定的解剖学,以获得最佳的兼容性.
