We report on the outcomes of flexor tendon repair in zone 2 subzones with early active mobilization in 102 fingers in 88 consecutive patients. There were 28, 53, 15, and six fingers with repairs in zones 2A to 2D, respectively. Rupture of the repair occurred in four fingers, all in zone 2B. Excluding those with repair ruptures, the mean total active motion was 230° (range 143°-286°). Evaluated with Tang's criteria, the outcomes were ranked excellent in 39 fingers, good in 46, fair in ten, poor in three, and failure in four. The outcomes in zone 2C were significantly inferior to those in zones 2B and 2D ( p = 0.02). Our results suggest that the tendon laceration in the area covered by the A2 pulley (zone 2C) is the most difficult area to obtain satisfactory active digital motion and tendon repair in zone 2B is the area where the risk of rupture is highest.

我们报告了88例连续患者102根手指在2区亚区进行屈肌腱修复并早期主动活动的结果。分别有28根、53根、15根和6根手指在2A至2D区进行了修复。修复处断裂发生在4根手指，均在2B区。排除修复处断裂的患者，平均总主动活动度为230°（范围143° - 286°）。根据唐的标准评估，结果为优的有39根手指，良的有46根，可的有10根，差的有3根，失败的有4根。2C区的结果明显不如2B区和2D区（p = 0.02）。我们的结果表明，A2滑车覆盖区域（2C区）的肌腱撕裂是获得满意的手指主动活动最困难的区域，2B区是修复处断裂风险最高的区域。
