Modified percutaneous trigger finger release.

UNLABELLED: Stenosing tenosynovitis or trigger finger is one of the most common disorders that affect the flexor tendon apparatus of the hand. Percutaneous release has been previously reported to be easier, quicker, less invasive and less costly than open surgery. The purpose of this study was to report the outcome of an alternative percutaneous trigger finger release technique. From March 2008 to January 2014, 92 patients (128 fingers) who underwent the alternative percutaneous trigger finger release, with a minimum of 6 months follow-up were included. Outcomes included size of skin incision, pain, residual symptoms, satisfaction and complications. Percutaneous release was achieved in all fingers, except 1 for which an opening of the skin was necessary to complete the release of the pulley. Eight fingers (6%) required revision open surgery because of persistence of their symptoms. At 1 week after the procedure, no finger swelling was reported, however 4 fingers (3%) were painful and 45 (35%) were stiff and required physiotherapy. Percutaneous release was successful in 120 fingers (94%). At the final follow-up, all the patients were satisfied by the procedure (95 rated their result as much better and 32 as better). This study shows that our alternative percutaneous trigger finger release is a reliable and safe procedure with high patient satisfaction.

LEVEL OF EVIDENCE: Level IV, clinical study, therapeutic study.
