This study compares the active ranges of finger motion and rupture rates of two-strand and four-strand repairs in zone 2 flexor tendon lacerations in young children. A total of 29 patients (under the age of 4 years) with 32 flexor tendon lacerations in zone 2 were evaluated. The injured tendons were randomly repaired with either two-strand or four-strand modified Strickland techniques. At a mean follow-up period of 11 months, the mean total active motion of interphalangeal joints was 156 degrees in the two-strand and 158 degrees in the four-strand group. According to the Strickland original method, this means an average of 89% (range 57-100%) of normal function in the two-strand and 90% (range 60-100%) in the four-strand group. There were no ruptures of the four-strand repairs, but one two-strand repair failed within 3 weeks of the repair. Statistically, we were not able to show any significant difference in the active ranges of finger motion achieved with two-strand and four-strand repairs.
本研究比较了幼儿2区屈指肌腱损伤采用双股和四股修复时的手指活动范围及断裂率。共评估了29例（4岁以下）2区屈指肌腱损伤患者的32条肌腱。损伤肌腱随机采用双股或四股改良Strickland技术修复。平均随访11个月时，双股修复组指间关节平均总主动活动度为156度，四股修复组为158度。根据Strickland原始方法，这意味着双股修复组平均功能为正常的89%（范围57 - 100%），四股修复组为90%（范围60 - 100%）。四股修复无一例断裂，但有一例双股修复在修复后3周内失败。统计学上，我们未能显示双股和四股修复在手指活动范围上有任何显著差异。
