Abstract

The purpose of this prospective review was to evaluated the natural course of spontaneous resolution of trigger thumbs in children. From March 1996 to April 1998, Twenty four patients with thirty two thumbs involved were identified with trigger thumb of childhood. The diagnosis was made at the initial outpatients visit. In nine cases, the right hand was affected, in seven the left, and in eight patients there was bilateral involvement. Follow-up time ranged from twenty four to fifty three months(median,36.5 months). During last follow-up, Surgery was performed in five patients with eight thumbs after the diagnosis of a trigger thumb. In nineteen patients with twenty four thumbs(79%), symptom was improve. Symptom was not improved in five patients with five thumbs(21%). We thought that symptom of trigger thumb became improved because of bone, tendon and joint growth or reduced size of nodule associated with enlarged A1 pully.
