What Is Trigger Finger Release?
Trigger finger release is a surgical procedure aimed at treating trigger finger, a condition characterised by locking or catching a finger or thumb in a bent position. This condition is caused by inflammation and narrowing of the tendon sheath, a protective covering surrounding the flexor tendons, enabling finger bending and straightening.
When is Trigger Finger Release Needed?
- Persistent Locking
The surgery is indicated when the affected finger or thumb remains locked in a bent position and cannot be straightened without assistance, indicating a severe restriction of movement. - Non-responsiveness to Non-surgical Treatments
If symptoms persist despite non-surgical treatments such as splinting, anti-inflammatory medications, or steroid injections, surgical intervention may be necessary. - Significant Pain and Discomfort
Surgery may offer the best chance for relief when the condition causes considerable pain or discomfort, especially during movements or when gripping objects. - Impact on Daily Activities
Surgery is also considered when a trigger finger significantly affects the ability to perform daily tasks and impacts the quality of life.
Benefits and Risks of Trigger Finger Release
Benefits
- Improved Finger Movement: Restores normal movement, allowing patients to bend and straighten the finger without discomfort.
- Pain Relief: Provides significant relief from the pain and tenderness in the affected finger or thumb.
- Increased Hand Function: Enhances the overall function of the hand, facilitating daily activities and tasks.
Risks
While the risks associated with trigger finger release surgery are generally low, patients need to understand that complications, though rare, can be serious and require immediate attention. These risks include:
- Infection: There is a risk of infection at the incision site, although it is generally low and manageable with proper care.
- Nerve Damage: There is a small risk of damage to the nerves near the surgical site, which could result in numbness or changes in sensation.
- Scar Formation: Some patients may develop scar tissue at the site of the surgery, affecting finger movement.
- Recurrence: Symptoms of trigger finger may recur in rare cases, possibly necessitating further treatment.
Preparing for Trigger Finger Release
Medical Evaluation
Medication Review
Inform the surgeon about all medications and supplements to identify any necessary adjustments before surgery.
Fasting
Depending on the type of anaesthesia, fasting for several hours prior to the procedure may be required.
What Can You Expect During a Trigger Finger Release?
- Anaesthesia
The procedure is typically outpatient and is performed under local anaesthesia. Only the hand area is numbed, allowing patients to remain awake without pain. - Observation
Patients are often observed for a short period after the surgery to ensure there are no immediate complications before being allowed to go home. - Tendon Sheath Release
The surgeon carefully cuts through the constricted section of the tendon sheath to release the tendon and allow it to move freely. - Closure
The incision is then closed with stitches, and a bandage is applied to protect the area. - Duration
The entire procedure usually takes less than an hour to complete. - Incision
A small incision is made in the palm or at the base of the affected finger.
Postoperative Care and Recovery
Bandage Care
Keep the bandage clean and dry. The surgeon will give specific instructions on when it can be removed or changed.
Pain Management
Mild to moderate pain may be experienced, which can typically be managed with prescribed or over-the-counter pain relievers.
Activity Restrictions
Initially, avoid using the operated hand for strenuous activities such as lifting heavy objects, gripping tightly, or performing repetitive movements. Gradually reintroduce light activities, such as gentle finger movements and soft grip exercises, following your surgeon’s guidance.
Follow-up Visits
Attend scheduled follow-up appointments for stitch removal and to assess healing progress.
Physical Therapy
Engaging in physical therapy or hand therapy exercises may be recommended to restore movement and strength.
Monitoring for Complications
Watch for signs of infection, such as increased redness, swelling, or unusual discharge from the incision site, and report any concerns to the specialist immediately.

Frequently Asked Questions (FAQs)
How Long Does It Take to Recover From Trigger Finger Release Surgery?
Recovery time from trigger finger release surgery can vary significantly. Most patients notice a reduction in symptoms and improvement in finger mobility within a few weeks of the surgery.
However, achieving full recovery and regaining complete function may take up to several months, depending on individual healing processes and the degree of adherence to postoperative rehabilitation instructions.
Is Trigger Finger Release Surgery Painful?
Postoperative pain following trigger finger release surgery is typically mild to moderate and can be effectively managed with medications. It is common for patients to experience some discomfort and swelling in the operated area, which gradually subsides over the first few weeks.
Can Trigger Finger Recur After Surgery?
The likelihood of trigger finger recurring after surgery is relatively low but not entirely eliminated. Recurrence can happen, particularly in cases where the initial cause of the condition, such as repetitive strain or underlying medical conditions like diabetes, remains unaddressed. Regular follow-up and adherence to recommended hand usage guidelines can help minimise the risk of recurrence.
What Are the Signs That I Might Need Trigger Finger Release Surgery?
Signs that trigger finger release surgery might be needed include persistent locking or catching of the finger despite non-surgical treatments, significant pain that interferes with daily activities, and inability to fully straighten or bend the finger.
If conservative measures like splinting, medication, or steroid injections fail to alleviate these symptoms, surgical intervention may be considered to restore normal finger movement and relieve discomfort.
