Pediatric trigger thumb and trigger finger represent distinct conditions and should not be treated like adult acquired trigger finger. Over the last two decades, our understanding of the natural history of pediatric trigger thumb and the etiology and surgical management of pediatric trigger finger has improved. Pediatric trigger thumb may spontaneously resolve, although resolution may take several years. Open surgical release of the A1 pulley of the thumb is an alternative option that nearly uniformly restores thumb interphalangeal joint motion. Surgical management of pediatric trigger finger with isolated release of the A1 pulley has been associated with high recurrence rates. Awareness of the anatomic factors that may contribute to triggering in the pediatric finger and willingness to explore and address other involved components of the flexor mechanism can prevent surgical failure.
小儿扳机指和扳机拇指是两种不同的疾病，不应像成人获得性扳机指一样进行治疗。在过去的二十年中，我们对小儿扳机指的自然病程、病因以及小儿扳机拇指的手术治疗有了更好的理解。小儿扳机指可能会自行缓解，尽管缓解可能需要数年时间。切开松解拇指 A1 滑车是另一种选择，几乎可以完全恢复拇指指间关节的活动度。单独松解 A1 滑车治疗小儿扳机拇指，其复发率较高。了解可能导致小儿手指扳机现象的解剖因素，并愿意探索和解决屈肌机制的其他受累成分，可以预防手术失败。
