Percutaneous release of A1 pulley.
We performed 100 percutaneous releases of the trigger digits in a cadaveric model using an 18-gauge needle. Successful percutaneous release was achieved for only 59 digits (59%). No neurovascular injury occurred. We found that a percutaneous trigger digit release resulted in high percentage of incomplete releases of A1 pulley, especially in the thumb, index, and little fingers.
