Aim: Stenosing tenosynovitis, known as trigger finger, is one of the most commonly seen hand pathologies, causing pain and impaired function in the hand. In this study, the patients were separated into 4 groups according to the treatment applied and an evaluation was made of the efficacy of these treatment options on different grades. Material and Method: A retrospective evaluation was made of 543 patients, 301 females and 242 males diagnosed with trigger finger affecting the A1 pulley between February 2011 and January 2015. Patient data were obtained from hospital records and the patient clinical records. The Quinnell grading system was used to grade the trigger fingers. Results: When the work modules were evaluated according to the grades and the treatments applied to the patients, with the exception of the oral NSAID group, a statistically significant improvement was determined in the work module for all grades compared to the preoperative values of the local corticosteroid, percutaneous release, and open release treatments (p<0.05). In the oral NSAID group, the post-treatment values were similar to the pre-treatment values and there was no significant difference. Discussion: In light of the data obtained in this study, it was seen that as the grade increased in trigger finger, more satisfactory results were provided by more invasive treatment options to remove the negative effects on functional performance and kinematics.
