[The effect of percutaneous trigger finger release on normal anatomic structures and long-term results of the procedure].

OBJECTIVES: To evaluate the long-term results and possible complications of percutaneous release in the treatment of trigger finger. METHODS: We performed percutaneous pulley release with the use of a 16 gauge needle in 25 fingers of 22 patients (16 females, 6 males; mean age 54 years; range 45 to 72 years). Open exploration was added to the procedure in 10 patients to determine the efficacy and safety of the technique. The mean follow-up was 24 months (range 18 to 35 months). RESULTS: Triggering and pain were eliminated in all fingers postoperatively. Exploration showed that a complete anatomical release of the pulley was obtained in all fingers. Apart from some superficial abrasions, there were no tendinous injury or other complications. In one case, an unintentional skin incision occurred during manipulation of the needle. CONCLUSION: Due to low complication rates and ease of the procedure with a successful release, percutaneous technique proved an appropriate alternative in the treatment of trigger finger
