Trigger finger.

I believe that percutaneous trigger finger release is a safe method. Many studies proved it.

We performed a randomized study in 150 trigger fingers. The study evaluated the effectiveness of CS injection, percutaneous pulley release and conventional open surgery for treating trigger finger in terms of cure, relapse and complication rates.[12]

We did not observe any lesion of the digital nerve among the three treatment groups, which would be a distressing factor, principally for the percutaneous method group. We believe that the demarcation of the longitudinal axis of the tendon in the percutaneous technique and precise anatomical knowledge of the pulleys are important factors for preventing complications, which is similar to the conclusion reached in anatomical studies.[3-5]

The percutaneous and open surgery methods displayed similar effectiveness and proved superior to the conservative CS method regarding the trigger cure and relapse rates.
