Trigger Finger Release Surgery

Trigger finger surgery involves open surgical release of the A1 pulley of the affected finger.

The surgeon makes a small incision in the palm at the base of the affected finger and divides the narrowed A1 pulley while protecting the surrounding nerves, blood vessels and tendons. The surgeon then checks that the tendon moves freely, closes the wound with sutures and applies a sterile dressing.

The procedure is generally performed on an outpatient basis under local anaesthesia. The treating physician determines the method of anaesthesia.

Following successful surgical release of the A1 pulley, triggering of the finger usually resolves. However, pain, swelling or stiffness may persist for several weeks to months.

In long-standing cases or where a contracture has already developed, the original range of finger movement may not be fully restored.

After surgery, the wound and dressing should be kept clean and dry. Keeping the hand elevated during the first few days may help reduce swelling.

Gentle active bending and straightening of the fingers should begin as tolerated and according to the physician’s recommendations. Until approved by the treating physician, forceful gripping, putting weight on the palm and heavy manual activities should be avoided.

Wound checks and suture removal are often carried out approximately 10–14 days after surgery. The return to work and sport varies individually. If stiffness persists, the physician may recommend hand therapy.

Common or temporary postoperative effects include pain, swelling, bruising, minor bleeding, scar tenderness, finger stiffness and temporarily reduced grip function.

Less commonly, infection, wound-healing problems, persistent pain, incomplete pulley release or recurrence of symptoms may occur. Rare complications include injury to a nerve, blood vessel or tendon, or complex regional pain syndrome (CRPS).

Depending on the severity of symptoms, alternatives may include observation, activity modification, a splint or a corticosteroid injection.
