Prospective randomized trial of open versus percutaneous surgery for trigger digits

Abstract Various methods for the treatment of trigger digits exist. This study was designed to compare the results of an open surgical technique with those of a percutaneous surgical technique for the treatment of trigger digits. Ninety-six patients with 100 trigger digits were randomized to either open (n = 46) or percutaneous (n = 54) surgical release of the first annular pulley. Operation time, duration of postoperative pain, recovery of motor function, and surgical complications were assessed. Trigger digits were successfully treated in 98% of the cases using the open surgical technique and in 100% of the cases using the percutaneous technique. Mean operation time was significantely longer using the open technique. Mean duration of postoperative pain and time to recovery of motor function were significantely shorter for patients treated with the percutaneous method. No serious complications were observed in either group. We conclude that percutaneous correction of trigger digits is a quicker procedure, is less painful, and shows significantly better results in rehabilitation than open surgery.
