Efficacy of percutaneous release of trigger finger

Abstract

Trigger finger is one of the most common cause of pain and disability of the hand. This condition results in painful catching or popping of the involved flexor tendon as the patient flexes and extends the digit. This study aimed to test the efficiency of percutaneous release in the treatment of Trigger Finger in 100 patients. Percutaneous Release of A1 pulley of the affected digit was performed using 18G needle under Local Anaesthesia in the Out Patient Department. Results were graded using Quinnel's criteria as excellent if there was no pain after the procedure, good if pain occurred with heavy use or poor if there was no reduction in pain. Excellent result was achieved in 83 patients while good results achieved in 13 patients who were satisfied and were able to return to their work the next day of the procedure. In 4 patients the procedure failed to relieve the symptoms and there was some degree of residual triggering and pain left. At 1 week follow up only 9 patients had some degree of pain and stiffness which had completely resolved on taking medication and there were no complaints at 3 months follow up. Percutaneous release is a safe, effective and cheap procedure, providing immediate relief from symptoms in the treatment of trigger finger which is well tolerated and has a low rate of complications when done by an experienced Orthopaedic surgeon.
