A specially designed tensiometer was employed to compare the mechanical efficiency of normal and reconstructed pulley systems in the thumb and the fingers. The "belt loop" technique for reconstruction was used in five fresh cadavers. A total of 10 thumbs and 40 fingers were dissected, and after a measured pull on the proximal tendon the yielded power output at the tip was compared with the normal and reconstructed systems. A mean of 10% loss of power in the reconstructed system in the thumb and 40% of power in the fingers, with excellent range of motion and no bow stringing was recorded.
使用一种专门设计的张力计来比较拇指和手指中正常和重建滑轮系统的机械效率。在五具新鲜尸体上采用了“带袢”重建技术。总共解剖了10个拇指和40根手指，在对近端肌腱进行测量拉力后，将指尖处产生的功率输出与正常和重建系统进行比较。结果显示，重建系统中拇指的功率平均损失10%，手指的功率损失40%，同时记录到关节活动范围良好且无弓弦状畸形。
