Objectives/Interrogation: To evaluate the safety, efficacy, recovery time and repercussion on the functional status of the percutaneous surgery technique for the treatment of trigger finger.

Methods: A two phase study was designed. In the first phase, percutaneous release of A1 pulley was performed in cadaver hands and verified by an incision over the A1 pulley. In the second phase, after informed consent, 20 patients underwent percutaneous release of the A1 pulley with an intramuscular needle. Preoperative and post operative functional status was assessed by the QuickDASH score before and 2 weeks after the procedure. Parameters like pain during the intervention and in the post-op period, time to return to work, patient satisfaction, recurrence of trigger finger and complications were also evaluated.

Results and Conclusions: Patients got back to daily life tasks and to work before than the mean time described in the literature with the open surgery procedure, as well as had a shorter time of pain post-op. We had few complications and all the patients improved their functional status measured with the QuickDASH score after the procedure.

Percutaneous surgery for trigger finger has shown to be a safe technique, with faster recovery than the open surgery, even in centers more experienced with the open technique.
