30 consecutive adult patients presenting with trigger thumb (31 thumbs) were entered prospectively into a study to determine the natural history of the condition. Five patients insisted on treatment and could not be followed to resolution, but the rest resolved spontaneously after an average duration of symptoms of 6.8 months (range 2-15). There was a small but non-functional reduction in movement of the thumb in some of the patients: six lost an average of 7 degrees of abduction and ten had an average loss of opposition of 1.4 (Kapandji grade). The remaining patients made a full recovery.
30例连续成年扳机指患者（共31个拇指）被前瞻性纳入一项研究，以确定该病的自然病程。5例患者坚持治疗，未能随访至病情缓解，但其余患者在平均症状持续6.8个月（范围2 - 15个月）后自发缓解。部分患者拇指活动度有轻微但不影响功能的降低：6例患者外展平均丧失7度，10例患者对掌平均丧失1.4（Kapandji分级）。其余患者完全恢复。
