Thread Trigger Finger Release

Thread trigger finger release is a minimally invasive surgical technique used to treat trigger finger, a condition where one of the fingers gets stuck in a bent position and may snap straight. This condition is also known as stenosing tenosynovitis. The procedure involves using a thread to release the constriction of the tendon sheath, allowing the affected finger to move freely.

Anatomy and Pathophysiology

The condition of trigger finger occurs when the flexor tendons in the hand become inflamed and swollen, leading to a narrowing of the tendon sheath. This results in difficulty in the smooth gliding of the tendon through the sheath, causing the finger to lock or catch during movement. The condition is often associated with repetitive gripping actions and is more common in individuals with diabetes mellitus and rheumatoid arthritis.

Indications for Procedure

Thread trigger finger release is indicated for patients who have not responded to conservative treatments such as nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroid injections, or splinting. It is particularly suitable for patients who prefer a less invasive option compared to traditional open surgery.

Procedure

The procedure is typically performed under local anesthesia. A fine thread is inserted through a small puncture in the skin near the affected finger. The thread is then maneuvered around the tendon sheath to cut through the constriction. This releases the tendon, allowing it to move freely. The procedure is quick, often taking less than 30 minutes, and does not require stitches.

Advantages

The thread trigger finger release offers several advantages over traditional open surgery:

• Minimally Invasive: The procedure involves only a small puncture, reducing the risk of infection and scarring.
• Quick Recovery: Patients typically experience a faster recovery time and can return to normal activities sooner.
• Cost-Effective: The procedure is often less expensive than open surgery due to its simplicity and reduced need for postoperative care.

Postoperative Care

After the procedure, patients are advised to keep the hand clean and dry. Mild pain and swelling can be managed with over-the-counter pain relievers. Patients are encouraged to perform gentle finger exercises to restore full range of motion.

Complications

While complications are rare, they can include infection, incomplete release of the tendon, or damage to surrounding structures. Patients should contact their healthcare provider if they experience severe pain, swelling, or signs of infection.
