We evaluated the factors influencing outcomes of flexor tendon repair in 112 fingers using a six-strand suture with the Yoshizu #1 technique and early postoperative active mobilization in 101 consecutive patients. A total of 32 fingers had injuries in Zone I, 78 in Zone II, and two in Zone III. The mean follow-up period was 6 months; 16 patients (19 fingers) participated in long-term follow-up of 2 to 16 years. The total active motion was 230° SD 29°; it correlated negatively with age. The total active motion was 231° SD 28° after repair of the lacerated flexor digitorum superficialis tendon, and was 205° SD 37° after excision of the flexor digitorum superficialis tendon ends (p = 0.0093). A total of 19 fingers showed no significant increases in total active motion more than 2 years after surgery. The rupture rate was 5.4% in our patients and related to surgeons' level of expertise. Five out of six ruptured tendons were repaired by inexperienced surgeons. Level of Evidence IV.
我们对101例连续患者的112根手指采用吉津1号技术的六股缝合线及术后早期主动活动，评估影响屈指肌腱修复效果的因素。共有32根手指在Ⅰ区受伤，78根在Ⅱ区，2根在Ⅲ区。平均随访期为6个月；16例患者（19根手指）参与了2至16年的长期随访。总主动活动度为230°标准差29°；与年龄呈负相关。指浅屈肌腱断裂修复后总主动活动度为231°标准差28°，指浅屈肌腱断端切除后为205°标准差37°（p = 0.0093）。共有19根手指在术后2年以上总主动活动度无显著增加。我们患者的肌腱断裂率率为5.4%，且与外科医生的专业水平有关。六根断裂肌腱中有五根是由经验不足的外科医生修复的。证据等级为Ⅳ级。
