Trigger finger is the second cause of consultation with the hand surgeon. In 2009, Kerrigan published a strategy for the treatment of this pathology, which consists of two infiltrations with corticosteroids in the sheath of the flexor tendons at the level of the A1 pulley, followed by percutaneous or open surgical release, following the algorithm described by the author. 140 files that met the inclusion criteria were analyzed. It was found that the female gender is the most frequently affected during the sixth decade of life in 46%. The most frequently affected finger is the third, affects the right hand in 44% and both hands in 29%. 91% of the patients received a first infiltration and only 31% of these received a second infiltration. The surgical procedure was decided in 33% of the patients. The longest follow-up was 180 months and the shortest was 3 months with 100% of asymptomatic patients. The algorithm proposed by Kerrigan in the treatment of this pathology is a good strategy that has a high success rate without having to perform a surgical procedure as the first treatment option.
