We performed 118 percutaneous releases of the locked trigger digits in an office setting using a specially designed knife. Thirty-five digits were locked in flexion, 79 digits in extension and the remaining four were fixed in a semiflexed position. Successful percutaneous release was achieved for 107 digits (91%), with the remaining 11 digits requiring an open surgical procedure. Although there were no persistent triggering in 98 digits with a follow-up of at least 6 months, painful stiffness at the interphalangeal joints remained in ten digits despite of physical therapy. No neurovascular injury occurred. We suggest that a locked trigger digit can be successfully released with the percutaneous technique.
