Trigger finger causes pain and a persistent functional limitation of the hand, which can lead to permanent blockage of the flexor tendon. Ultrasonography-guided percutaneous release has been widely reported as a successful technique for trigger finger involving the A1 pulley. This article describes for the first time the use of this technique in an unusual location, the A3 pulley of the fifth finger. A 71-year-old patient presented with a 3-month history of pain and blockage in the fifth finger of the right hand and was diagnosed with a grade III trigger finger, according to the Froimson scale. We performed an ultrasonography-guided percutaneous release technique on the A3 pulley to release the flexor tendon of the fifth finger. Ultrasonography-guided percutaneous polectomy to treat trigger finger in the A1 pulley is an effective alternative treatment to surgery and even has certain advantages over it. The anatomical similarity between the A1 and A3 pulleys was the key factor that supported the use of this technique in this clinical case. Based on past experience in similar cases, we conclude that ultrasonography-guided percutaneous polectomy of the A3 pulley of the fifth finger was a surgical technique which could lead to a satisfactory outcome in the treatment of this condition.
