Intratendinous metal markers were used to study flexor digitorum profundus tendon excursions during early controlled motion with dynamic flexion traction and to evaluate their significance for results after flexor tendon repair in zone II. The mean excursion was 1 mm along the middle phalanx and 5.6 mm along the proximal phalanx. This corresponded to a mean excursion per 10 degrees of controlled distal and proximal interphalangeal joint motion of 0.3 and 1.2 mm, respectively. Compared to active motion, controlled motion of the distal interphalangeal joint mobilized the tendon with an efficiency of 36% and controlled motion of the proximal interphalangeal joint mobilized the tendon with an efficiency of 90%. Controlled-motion excursions induced by the distal interphalangeal joint along the middle phalanx had little influence on subsequent active range of motion in the distal interphalangeal joint, whereas excursions along the proximal phalanx (for which the proximal interphalangeal joint was largely responsible) did have a significant influence on subsequent total active interphalangeal range of motion.
采用腱内金属标记物研究在早期动态屈曲牵引控制活动期间指深屈肌腱的活动情况，并评估其对Ⅱ区屈肌腱修复术后结果的意义。沿中节指骨的平均活动度为1mm，沿近节指骨的平均活动度为5.6mm。这分别对应于远侧和近侧指间关节每控制活动10度时肌腱的平均活动度为0.3mm和1.2mm。与主动活动相比，远侧指间关节的控制活动使肌腱活动的效率为36%，近侧指间关节的控制活动使肌腱活动的效率为90%。远侧指间关节沿中节指骨产生的控制活动对远侧指间关节随后的主动活动范围影响较小，而沿近节指骨的活动（近端指间关节对此起主要作用）对随后的指间关节总主动活动范围有显著影响。
