Comparison of Two Surgical Techniques for the Treatment of Trigger Fingers: Longitudinal Opening Versus Complete A1 Pulley Release

Sponsor: Centre hospitalier de l'Université de Montréal (CHUM)

Summary

Trigger finger is a pathology of the flexor tendons caused by inflammation of the tendon or its sheath, leading to pain, nodules, fibrosis, and limited mobility. Surgical treatment aims to release the space at the level of the A1 pulley, either through longitudinal opening (the standard technique, but associated with recurrence rates of approximately 7.7%) or through complete resection, an emerging approach that may reduce recurrences and the need for reoperations. However, comparative data remain limited, justifying further investigation. This project therefore aims to compare these two surgical techniques to determine which one results in the lowest recurrence rate and to assess their functional outcomes (pain, range of motion). The primary hypothesis is that A1 pulley resection reduces recurrences after one year, while the secondary hypothesis is that there is no significant difference in postoperative pain or mobility.
