VERGARA- AMADOR, Enrique; VIVEROS, Juan Manuel  and  SATIZABAL, Luis Alejandro. Incidence of trigger finger after carpal tunnel release. Salud, Barranquilla [online]. 2015, vol.31, n.3, pp.494-500. ISSN 0120-5552.  https://doi.org/10.14482/sun.31.3.6159.

Objective: To determine the incidence of TF in a cohort of patients who were operated with release of carpal tunnel. Materials and methods: It is a cohort of patients operated between October 2012 and October 2013 for moderate, advanced or extreme CTS. Results: 43 patients met the inclusion criteria. 48.8 % were machine operators and 34.9 % worked in general services. The time evolution of CTS was 4.1 years. The right hand was the most compromise and operated (62.8 %). The minimum follow-up was 10 months in average (5-20). 10 patients (23 %) developed trigger finger reported by the patient and confirmed by physical examination. Discussion: The CTS is often associated with the trigger finger. The beginning of the TF after surgery has a high incidence in the first 3 to 4 months. We had an incidence of 23 % in 43 patients operated with the same technique of minimal incision, with minimal follow up of 5 months. Almost all of TF appeared between the 4th and 6^th month after surgery. Postoperative edema and friction generated between the flexor tendon and the A1 pulley by sectioning the palmar retinaculum are factors in the genesis of TF. The thumb and middle finger developed the trigger more often (80 %).
