An apparatus has been designed to measure the in vivo forces transmitted along human hand flexor tendons during carpal tunnel release procedures. The tendon will be run through three hooks, the central one of which is attached to a load cell. The rationale is that once these forces are known this will aid in the design of repair techniques and rehabilitation regimens. As a first stage, an in vitro validation study is presented using cord subjected to varying forces to mimic an in vivo flexor tendon under varying conditions of use. Our results show that we can accurately and reproducibly measure the force in the cord.
已设计出一种装置，用于测量在腕管松解手术过程中沿人手部屈肌腱传递的体内力。肌腱将穿过三个钩子，其中央钩子连接到一个测力传感器。原理是一旦知道这些力，将有助于修复技术和康复方案的设计。作为第一阶段，进行了一项体外验证研究，使用承受不同力的绳索来模拟在不同使用条件下的体内屈肌腱。我们的结果表明，我们能够准确且可重复地测量绳索中的力。
