概括

在触发指手术中过度释放A2轮会增加弓风险. 释放高达一半的A2轮显著改变动力臂,并增加flexor digitorum profundus外游,表明更高的风险.

科学领域:

生物力学生物力学
整形外科手术整形外科手术
医疗成像医学成像

背景情况:

触发指通常需要A2滑轮释放.
过度释放A2滑轮可以导致弓绳,影响手指功能.
对于A2轮释放的安全极限还没有得到很好的定义.

研究的目的:

通过生物机械模型来确定A2轮释放的安全程度.
在A2滑轮释放后,分析肌外流效率和动力臂相对于指关节的动量臂.

主要方法:

开发了一种生物机械模型的手指曲使用CT和MRI数据从八个主题.
模拟A1和A2轮的增量释放.
比较的关节时刻和计算的柔手指深部 (FDP) 游行,以获得最大的PIP关节曲.

主要成果:

在MCP关节的动力臂在释放后保持不变.
在PIP关节的动力臂显著增加,当A2轮释放达到其近端的一半.
与完整的手指相比,最大PIP flexion需要FDP外行的62%增加,而A2轮释放率为50%.

结论:

基于成像的生物机械模型可以准确地评估肌外行和瞬间臂.
释放到A2轮的近端一半增加了弓绳的风险.
这种建模方法可以预测各种手术中的肌外流效率.

关键词:

Muscles of the Forearm that Move the Hand and Fingers

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...
