In a cadaveric study the excursion of the flexor pollicis longus tendon has been measured over the proximal phalanx and metacarpal bones in relation to the angles of flexion of the interphalangeal (IP) and metacarpophalangeal (MP) joints. A small amount of tendon excursion is noted (1.3 mm for 10 degrees of IP joint flexion alone, 1.6 mm for 10 degrees of MP joint motion alone). It is emphasized that there is no tendon excursion over the proximal phalanx on MP joint motion. The significance of these measurements is considered in relation to current techniques of dynamic mobilization after tendon repair. Fixation of the MP joint and mobilization of the IP joint alone can achieve on an average a 70% increase in tendon excursion at the repair site over the proximal phalanx in comparison with dynamic splintage allowing free motion of both joints. The increase in excursion is greater in patients with more mobile MP joints.
在一项尸体研究中，已测量了拇长屈肌腱在近节指骨和掌骨上的滑动幅度，该滑动幅度与指间关节（IP）和掌指关节（MP）的屈曲角度相关。记录到少量的肌腱滑动（仅IP关节屈曲10度时为1.3毫米，仅MP关节活动10度时为1.6毫米）。需要强调的是，MP关节活动时，近节指骨上没有肌腱滑动。结合当前肌腱修复后的动态活动技术来考虑这些测量结果的意义。与允许两个关节自由活动的动态夹板固定相比，单独固定MP关节并活动IP关节，平均可使修复部位的肌腱在近节指骨上的滑动幅度增加70%。MP关节活动度更大的患者，滑动幅度的增加更为明显。
