Comparison of Two Surgical Techniques for the Treatment of Trigger Fingers: Longitudinal Opening Versus Complete A1 Pulley Release
236 participantsStarted 2026-04-01
Plain-language 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.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
