Trigger finger release is a surgical procedure performed to treat a condition called trigger finger or stenosing tenosynovitis. Trigger finger occurs when the tendons that control the movement of the fingers become inflamed and swollen, causing the affected finger to get stuck in a bent position and then suddenly snap straight.
The goal of trigger finger release surgery is to alleviate the symptoms and restore normal finger movement. Here’s an overview of the procedure:
1. Anesthesia:
Trigger finger release can be performed using either local anesthesia or regional anesthesia, depending on the patient’s preference and the surgeon’s recommendation. Local anesthesia numbs the hand, while regional anesthesia may involve an injection to block the nerves supplying the hand and arm.
2. Incision or Needle Technique:
Trigger finger release can be performed using either an open incision or a minimally invasive needle technique known as percutaneous release.
- Open Incision:
The surgeon makes a small incision in the palm or the base of the affected finger to access the tendon sheath. The incision allows for direct visualization and manipulation of the affected structures.
- Percutaneous Release:
With this technique, a needle is inserted through the skin at the base of the affected finger. The needle is guided to the site of the constricted tendon sheath, and the surgeon then manipulates the needle to release the tendon.
3. Release of the Constricted Tendon Sheath:
Once the surgeon has gained access to the affected tendon sheath, they carefully release the constricted portion of the tendon sheath or divide the thickened tissue causing the obstruction. This process allows the tendon to glide smoothly through the sheath, relieving the catching or locking sensation.
4. Closure and Recovery:
After the release of the tendon sheath, the incision is closed with sutures, adhesive strips, or surgical glue. The hand may be bandaged or splinted to provide support and protection during the initial healing phase. The surgery is usually performed on an outpatient basis, meaning the patient can go home on the same day.
5. Postoperative Care:
Following trigger finger release surgery, the hand will require some recovery time. The surgeon may recommend gentle finger exercises, hand therapy, and limited use of the hand to facilitate healing and restore finger mobility. Pain medication and ice application may be prescribed to manage any postoperative discomfort or swelling.
6. Return to Activities:
The time it takes to recover and resume normal activities varies among individuals. Most patients can start using their hand for light activities soon after surgery, while more strenuous activities may need to be avoided for a few weeks.
Trigger finger release surgery has a high success rate and generally leads to improved finger function and symptom relief. However, as with any surgical procedure, there are risks and potential complications, such as infection, scarring, nerve or blood vessel injury, and recurrence of symptoms.
