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

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.
