Pediatric trigger thumb (PTT) and finger (PTF) are upper extremity deformities that frequently go unrecognized by providers. Early recognition by pediatricians and caregivers is vital because PTT is successfully treated nonoperatively in more than 95% of patients if diagnosed early. Similarly, PTF can be successfully treated nonoperatively in 67% of patients. Although PTT is typically benign and 10 times more common, PTF may be associated with underlying concurrent medical conditions, such as juvenile rheumatoid arthritis, diabetes, mucopolysaccharide and lysosomal disorders, and trisomy 18. Routine examinations consisting of full hand range of motion should be performed in all children. Clinicians should be aware of the importance of conservative treatment options for PTT and PTF and the value of screening for underlying medical conditions associated with PTF.
小儿扳机指（PTT）和扳机指（PTF）是上肢的一种常见畸形，常被医疗服务提供者忽视。小儿科医生和护理人员的早期识别至关重要，因为如果早期诊断，超过 95%的 PTT 患者可以通过非手术成功治疗。同样，67%的 PTF 患者也可以通过非手术成功治疗。尽管 PTT 通常是良性的，且发病率比 PTF 高 10 倍，但 PTF 可能与潜在的并发疾病有关，如幼年特发性关节炎、糖尿病、黏多糖贮积症和溶酶体贮积症以及 18 三体综合征。所有儿童都应进行包括手部全范围活动的常规检查。临床医生应意识到 PTT 和 PTF 的保守治疗选择的重要性，以及筛查与 PTF 相关的潜在疾病的重要性。
