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...

概括

在逆肩关节整形术 (RSA) 中,最优的状腺植入物定位改善了运动范围 (ROM). 侧向和倾斜校正,使用角度增强器,提供最好的理论无冲击ROM.

科学领域:

整形外科手术整形外科手术
生物机械工程生物机械工程
医学成像和模拟技术

背景情况:

逆肩关节整形术 (RSA) 是复杂的肩部病理的一个常见程序.
实现最优的状腺植入物定位对于功能结果和防止撞击至关重要.
目前的状腺位置定位技术,包括横向化和倾斜校正,并没有得到一致的应用.

研究的目的:

确定最优的状腺植入物配置,以最大限度地实现在逆肩关节整形术 (RSA) 中无冲击的运动范围 (ROM).
使用3D规划软件,比较不同的状腺基板配置的理论ROM结果.

主要方法:

使用3D规划软件 (蓝图) 模拟了41名RSA患者的四个状腺基板配置.
配置包括RSA角度校正和侧面化的变化 (没有校正,媒介化,上方补偿,侧面化).
所有的模拟都使用相同的部内置植入物和135°倾斜的聚乙烯外.

主要成果:

具有横向化和RSA角度校正 (C + L +) 的配置显著改善了ROM在曲,延伸,加伸和外部旋转 (p ≤ 0.001) 中的性能.
内部旋转显示配置之间没有显著差异 (p = 0.388).
倾斜校正 (C+M+) 的媒介化导致在多个平面中最差的ROM.

结论:

将状腺的倾斜度纠正为0°,并使用8-10毫米的增强器将状腺组件横向化,可以在RSA中优化无冲击的ROM,具有135°的内嵌反转部植入物.
这种模拟方法为改善RSA手术规划和患者结果提供了理论基础.
