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

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.

Understanding Patient Preferences When Deciding on a Voluntary Musculoskeletal Test

The goal of this clinical trial is to understand how people make decisions about imaging tests for common musculoskeletal problems (like arthritis, tendon problems, or nerve compression). The study involves adult patients attending a musculoskeletal specialty clinic. The main questions it aims to answer are: 1. Does having a structured conversation about the pros and cons of a test affect how much a person wants to have that test? 2. Does that conversation help people feel more confident and less conflicted about their decision? Researchers will compare patients who have a values-based discussion with a researcher to those who receive brief written information about the test, to see if these approaches affect how people feel about having the test. Participants will: * Read a brief scenario about a proposed diagnostic imaging test (like an X-ray, MRI, CT, or ultrasound). * Either take part in a short structured conversation or read brief information about the test. * Answer a short survey about their thoughts on the test. This study does not involve actual medical testing or affect your clinical care. It is for research purposes only.

Pull-out Tenolysis Versus Simple A1 Pulley Release in Trigger Digits

Trigger finger is a common tendinopathy and clinically presents with painful catching or popping as the patient flexes and extends the digit, due to mechanical impingement of the thickened flexor tendons as they pass through a narrow tendon sheath canal at the level of the metacarpal head. If conservative management with corticosteroid injection and splinting fails or if symptoms recur, surgery and division of the A1 pulley are indicated. Traction (or pull- out) tenolysis is a maneuver based on pulling of the flexor tendons out of the wound, to release any adhesions that might have occurred due to long- standing triggering. Although it has been associated with postoperative pain and stiffness, no robust evidence exists to support its benefit or not. In view of the low quality evidence regarding the pros and cons of traction (or pull-out) tenolysis following A1 pulley release, the investigators will compare simple A1 pulley release versus A1 pulley release and pull-out tenolysis in a prospective randomized study design. Hypothesis of the study is that the pull- out tenolysis yields better results in terms of total active range of movement, pinch and grip strength, pain and quick-DASH scoring when compared to simple pulley release. The confirmation of the hypothesis will justify the use of pull-out tenolysis as a means of breaking any tendon adhesions and returning to normal function sooner. On the contrary, if the pull-out tenolysis is linked to a less favorable functional outcome, simple A1 pulley release will be recommended.
