Percutaneous release of trigger finger

Abstract

Background: trigger finger is a frequent and debilitating disease. Spontaneous long term resolution is rare. There are open techniques that offer good results but percutaneous techniques have been promoted. Objective: to characterize the results of percutaneous release in patients with trigger finger from March 2013 to march 2016. Methods: a prospective, descriptive and transversal study was conducted. The universe was made up with 47 patients and 57 fingers, selected by authors’ criteria. Descriptive and inferential statistics techniques were used. Results: women prevailed with 45 cases for 78,9 %. Most of the patients belonged to 50 a 59 age group with the 70,2 %. Dominant upper limb prevailed with 51 cases for 89,5 %. Third finger was the most affected one with 41 cases and 35 of them had a grade II stenosis. Preoperative evaluation showed that all fingers presented bad or regular evaluation. After surgery 56 fingers presented good or excellent results for a 98,2 %. Three patients had complications for a 5,2 %, which improved six months after the surgery. Conclusions: percutaneous release of trigger finger was effective in the majority of the patients, with good results at long term. It is an easy technique which needs a well knowledge of the anatomic zone to avoid complications.
