Effectiveness of Percutaneous Pulley Release With Infiltration, Versus Infiltration Alone in Trigger Finders

Effectiveness of Percutaneous A1 Pulley Release Under Ultrasound Guidance Associated With Infiltration, Versus Infiltration Alone, in Patients With Trigger Finders Who Have Failed a First Infiltration: a Randomized Controlled Trial

Study Type

INTERVENTIONAL

Conditions

Trigger Finger

Summary

Trigger finger is a mechanical problem characterized by pain and catching of digit in flexion. Histological changes of A1 pulley and synovial proliferation have been identified as factors that prompt trigger finger The first-line treatment of trigger finger is conservative with splinting and corticosteroid injection. If the first infiltration fails, either a second infiltration or surgical sectioning of the pulley is proposed. Surgery can be performed by several techniques (open section, percutaneous section with palpatory guidance, or under ultrasound guidance). Percutaneous A1 pulley release under ultrasound guidance consists of cutting the A1 pulley by a percutaneous insertion with small needle under local anaesthesia. The hypothesis of the study is that percutaneous A1 pulley release under ultrasound guidance followed by a corticosteroid injection would be more effective than a second corticosteroid injection alone on complete resolution of the trigger finger symptoms

Plain Language Summary

Simplified for easier understanding

This study compares two treatments for trigger finger — a condition where a finger gets stuck or catches when bent. One treatment is a corticosteroid injection alone; the other is injection plus a needle-based procedure (percutaneous pulley release) to cut the tight tissue causing the problem. Researchers want to find which approach works better. You may be eligible if: - You are 18 years of age or older - You have a trigger finger that needs treatment - Your trigger finger severity is Quinnell score greater than 1 - A first corticosteroid injection more than 3 months ago did not work - An ultrasound shows thickening of the A1 pulley (the tight tissue causing the problem) of 0.5 mm or more You may NOT be eligible if: - You have multiple symptomatic trigger fingers that all need treatment - You are pregnant, breastfeeding, or could become pregnant without effective contraception - You are allergic to corticosteroids or local anesthetic (lidocaine) - You are taking anticoagulant medications (blood thinners) - You have an active infection, inflammatory joint disease (e.g., rheumatoid arthritis), or Dupuytren's disease - You have had previous finger surgery Talk to your doctor to see if this trial is right for you.
