Abstract: © 2014, Medical Association of Thailand. All Rights Reserved. Objective: To observe and evaluate the treatment outcome of pediatric trigger thumb in patients who had undergone surgical release of the annular ligament with the oblique pulley partially released in patients who did not achieve full IP joint extension. Material and Method: From 2003 to 2010, 21 surgically operated thumbs in 17 patients were reviewed. Bowstringing, range of motion (ROM) of thumb interphalangeal joint, Notta’s node resolution and assessment of patient/parent satisfaction were used as outcome parameters. The pulley pathology system was observed intra-operatively. The annular ligament was completely released, and in patients who were not fully corrected, a further procedure in which 50% of the oblique pulley was released was undertaken. Results: One thumb had recurrent triggering after 60 months of follow-up. No infection, neurovascular injury, excessive scarring, or bowstringing were detected. Notta’s node was fully resolved in all operated thumbs. Mean follow-up was 64 months. Improved IP joint motion without flexion contracture was observed in all patients. The procedure was well tolerated by patients and both the patients and parents of patients expressed satisfaction with the results of the procedure. Conclusion: Surgical release is recommended for children aged more than one year that are afflicted with trigger thumb. This procedure delivers satisfactory results with minimal complications. To achieve full FPL excursion, some patients need to release 50% of the oblique pulley after the first procedure.
