All about trigger finger release surgery

Trigger finger, medically known as stenosing tenosynovitis, is a common condition that causes a finger or thumb to catch, lock, or snap when bent. This happens because the tendon sheath that guides the finger tendons becomes inflamed or narrowed, restricting smooth movement. While many cases can be managed conservatively, severe or persistent trigger finger may require surgical intervention known as trigger finger release surgery.

Trigger finger release surgery is a procedure aimed at relieving the constriction of the tendon sheath to allow the tendon to glide freely again. The surgery involves cutting the tight pulley (called the A1 pulley) that is causing the tendon to catch. This relieves the pressure and restores normal finger movement.

Most mild cases of trigger finger improve with rest, splinting, anti-inflammatory medications, or corticosteroid injections. However, if these treatments fail or if the finger becomes locked in a bent position, surgery may be recommended. Surgery is typically considered when symptoms significantly affect daily activities or cause pain and stiffness.

Trigger finger release is usually performed as an outpatient procedure under local anaesthesia. The surgeon makes a small incision near the base of the affected finger to access and release the pulley. The operation typically takes less than 30 minutes.

After surgery, patients might experience mild soreness or swelling, but most regain full function within a few weeks. Physical therapy or gentle exercises may be advised to restore strength and flexibility. The success rate for trigger finger release surgery is high, with most patients experiencing complete relief from symptoms. In summary, trigger finger release surgery is a safe and effective treatment for those with persistent or severe trigger finger, helping to restore smooth finger movement and improve quality of life.
