Trigger finger surgery

Trigger finger surgery, also known as trigger finger release, is a procedure designed to alleviate the symptoms of trigger finger (stenosing tenosynovitis).

This condition occurs when the tendon sheath in the finger becomes inflamed, causing the finger to catch or lock when bent. Surgery aims to release the constricted tendon sheath, allowing the tendon to move freely and restoring normal finger function.

What you need to know

Suitability

Trigger finger surgery is suitable for individuals who experience persistent symptoms or pain that has not improved with non-surgical treatments such as splinting, anti-inflammatory medications, or steroid injections.

Candidates will often find their daily activities and hand function are significantly affected by the condition.

Long-Term Outcomes

The long-term outcomes of trigger finger surgery are usually very positive, with most patients experiencing significant relief from symptoms and improved hand function. The procedure has a high success rate, and recurrence of trigger finger in the treated finger is rare. Maintaining hand health through proper ergonomics and avoiding repetitive strain can help sustain the benefits of the surgery

Procedure details

Trigger finger surgery is typically performed on an outpatient basis under local anesthesia. The procedure involves making a small incision in the palm near the affected finger. Through this incision, the surgeon can access the tendon sheath and carefully cut or release the constricted portion. This release allows the tendon to move freely without catching or locking. The incision is then closed with sutures, and a dressing is applied to protect the area during the initial healing period. The entire procedure usually takes about 15 to 30 minutes.

Procedure process

Anesthesia: The procedure is usually performed under local anesthesia, numbing the affected hand and allowing the patient to remain awake but pain-free during surgery.

Incision: A small incision is made in the palm of the hand near the base of the affected finger. The size of the incision is typically minimal to reduce scarring and promote quicker healing.

Release of Tendon Sheath: Ms Teo locates the constricted portion of the tendon sheath and carefully cuts it to release the pressure on the tendon. This allows the tendon to glide smoothly through the sheath.

Closing the Incision: The incision is closed with sutures, and a sterile dressing is applied to protect the wound.

Post-Operative Care: The patient is usually advised to keep the hand elevated to reduce swelling and may be provided with a splint to support the finger during initial healing. Physical therapy exercises are often recommended to restore full range of motion and strength.

Recovery

Recovery from trigger finger surgery is relatively quick. Patients can expect some swelling, stiffness, and minor discomfort in the hand, which can be managed with over-the-counter pain medications and ice packs. It is important to keep the hand elevated and avoid heavy use of the affected hand for a few days.

Most individuals can resume light activities within a week but should avoid strenuous activities and heavy lifting for at least four to six weeks. Following your surgeon’s post-operative care instructions, including prescribed exercises to restore movement, is crucial for optimal healing and results.

Potential complications

As with any surgical procedure, trigger finger surgery carries risks such as infection, bleeding, scarring, and adverse reactions to anesthesia. Specific complications might include stiffness, tenderness at the incision site, and incomplete relief of symptoms. It's important to follow your surgeon’s post-operative instructions closely and attend all follow-up appointments to monitor your recovery and address any concerns promptly.

 FAQs

  • Trigger finger surgery, also known as tenolysis or trigger finger release, is a procedure designed to alleviate the symptoms of trigger finger by releasing the constricted tendon sheath, allowing the tendon to move freely and restoring normal finger function.

  • Good candidates include individuals with persistent or severe symptoms that have not responded to conservative treatments, those with fingers locked in a bent position, individuals with recurrent symptoms, or patients with multiple fingers affected by trigger finger.

  • The procedure involves making a small incision in the palm near the base of the affected finger, releasing the constricted portion of the tendon sheath to allow the tendon to glide smoothly, and then closing the incision with sutures.

  • The incision made during trigger finger surgery is small, and any resulting scar is usually minimal and fades over time. Some patients may experience sensitivity or tenderness at the scar site.

  • Most patients experience significant improvement within a few weeks. Full recovery, including the return to all activities, typically occurs within a few months. Patients are often advised to keep the hand elevated, use a splint, and perform physical therapy exercises during recovery.

  • While surgery aims to provide lasting relief, there is a small risk of recurrence. However, most patients experience significant and long-lasting improvement.

  • Trigger finger surgery is typically covered by health insurance, especially if it is performed to alleviate pain or functional limitations. Check with your insurance provider for specific coverage details.
