Trigger thumb is an uncommon problem in infants and children. The authors reexamined 21 patients (30 thumbs) who underwent a release procedure, with an average follow-up of 181.3 months (15.1 years). Twenty-three percent of patients had a loss of interphalangeal motion and 17.6% had metacarpal phalangeal hyperextension, and this was unrelated to age at the time of surgery. There was no recurrence of triggering or nodules and no functional deficit. All seven patients who had a longitudinal incision had concerns about their scar appearance. It is the authors' belief that a transverse skin incision and surgical release of the A(1) pulley for trigger thumb in children is a successful procedure even when done after age 3, but interphalangeal motion loss and metacarpal phalangeal hyperextension may occur in the long term.
扳机指在婴幼儿中是一种罕见的问题。作者对21例接受松解手术的患者（30根拇指）进行了复查，平均随访时间为181.3个月（15.1年）。23%的患者指间关节活动丧失，17.6%的患者掌指关节过度伸展，这与手术时的年龄无关。没有出现扳机现象或结节复发，也没有功能缺陷。所有7例采用纵向切口的患者都对其瘢痕外观有所顾虑。作者认为，对于儿童扳机指，即使在3岁以后进行，横向皮肤切口和A（1）滑车的手术松解也是一种成功的手术方法，但长期来看可能会出现指间关节活动丧失和掌指关节过度伸展。
