Open versus percutaneous release of the A1-pulley for stenosing tendovaginitis: a prospective randomized trial.
A prospective randomized trial for release of the first annular pulley (A-1 pulley) in trigger fingers with a percutaneous technique versus the open surgical technique is presented. Thirty-six patients were randomized to either open (n = 16) or percutaneous (#15 blade; n = 20) release of the A-1 pulley. All patients were evaluated for grip strength, active range of motion of the proximal interphalangeal joint, and residual pain at 1 and 12 weeks after release. Furthermore, the operation time was assessed, and the costs were calculated. Overall, 100% success in terms of grip strength, active range of motion of the proximal interphalangeal joint, and residual pain was obtained in both groups. Mean operation time was significantly longer with the open technique. Because of lower costs and quicker procedure with equal functional outcome when compared with open surgery, we recommend the percutaneous technique using a #15 blade for trigger finger release.
