Long-term results of percutaneous and open surgery for trigger fingers and thumbs.

Trigger digits can be treated surgically using a percutaneous or an open technique. The aim of this study was to evaluate the long-term results of the percutaneous and open surgery for trigger digits. The long-term results of 266 percutaneously released trigger digits and 70 open released trigger digits were evaluated. Recurrence of triggering occurred in 1% of patients after percutaneous release and 2% of patients after open release. After a mean follow-up period of 2.5 years, 17% of patients still had mild residual pain and 16% still had stiffness of the treated finger after percutaneous surgery. The open surgery group had a follow-up period of 5.5 years. Mild residual pain and stiffness persisted in 8% and 16%, respectively. After percutaneous surgery 3 (1%) patients suffered sensory loss on the radial side of the thumb. Compared to open surgery, percutaneous surgery resulted in significantly less scar formation. Ninety-six percent and 98% of patients were either satisfied or very satisfied with the result after percutaneous and open surgery, respectively. Both percutaneous and open surgery for the treatment of trigger digits have similar excellent long-term results.
