Outcome of Open Trigger Digit Release

Abstract

This study was undertaken to review the outcome of open trigger digit release of 483 digits in 373 consecutive patients over a 1 year period. Parameters were obtained from case records. The patients were followed up for a minimum of 6 months postoperatively. The most commonly affected digits were the ring (42%) and middle (26%) fingers. Based on the classification by Wolfe [Tenosynovitis. In: Green DP (Ed). Operative hand surgery, 5th Edn. New York, Churchill Livingstone, 2005: 2137–2159], Grade II (51%) and III (33%) trigger digits accounted for majority of affected digits. Non-operative treatment was the first line modality for 82% of the patients. Primary surgical release (18% of patients) was performed for patients who had refractory conditions, grade IV triggering and those who requested this treatment. The overall complication rate was 1%. These included superficial wound dehiscence, extension lag and postoperative residual stiffness. There were no recurrences of triggering. Steroid injection is recommended as the first line treatment. Surgical release is recommended for refractory and severe triggering.
