Background:
Even in the first application of patients with early complaints of trigger finger, pinch strength of the hand may be affected. Therefore, it is difficult to assess the change of strength as a result of treatment in this problem. In this study, we aimed to evaluate the change of strength taking into account both measured and expected pinch strengths before and after A1 pulley release surgery.
Methods:
Thirty fingers (9 thumbs, 12 middle, 8 ring and 1 index fingers) of 26 patients (17 women, 9 men) who underwent A1 pulley release were included into this study. The mean age of the patients was 53 (16-71). Tip-to-tip finger pinch strengths were measured pre-operatively and at 3 months postoperatively. The expected strengths were calculated using the values obtained from the healthy side and taking into account the dominance effect. In the analysis, pre-operative and postoperative measured strength/expected strength ratios were compared.
Results:
The mean of measured pinch strength/expected pinch strength ratio was 0.91 ± 0.3 pre-operatively and 1.14 ± 0.3 postoperatively (p < 0.05).
Conclusion:
With the calculation method used in this study, it was found that there was a significant increase in the tip-to-tip pinch strength after surgical A1 pulley release for the trigger finger.
Level Of Evidence:
III (Retrospective cohort study).
