Intratendinous metal markers were used to study the formation of gaps in flexor digitorum profundus tendon repairs during and after early controlled motion with dynamic flexion traction and to evaluate their significance for results in 34 digits with repairs in zone II. The mean (+/- SD) final repair elongation was 3.2 (+/- 3.6) mm. Linear regression analysis showed a general trend toward an inverse relationship between elongation and clinical results in terms of active interphalangeal joint range of motion, but the correlation was weak, and in the individual case gap formation was a poor predictor of clinical result. Gaps of up to 10 mm were quite compatible with good function. The results indicate that controlled motion is effective in restricting the formation of adhesions associated with gap formation during postoperative immobilization.
使用肌腱内金属标记物研究在早期动态屈曲牵引控制活动期间及之后，指深屈肌腱修复处间隙的形成情况，并评估其对34例Ⅱ区修复手指结果的意义。最终修复的平均（±标准差）伸长为3.2（±3.6）mm。线性回归分析显示，就主动指间关节活动范围而言，伸长与临床结果之间总体呈负相关趋势，但相关性较弱，且在个别病例中，间隙形成对临床结果的预测性较差。高达10mm的间隙与良好功能相当兼容。结果表明，控制活动可有效限制术后固定期间与间隙形成相关的粘连形成。
