Trigger Finger (Stenosing Tenosynovitis)
What is it?
Trigger finger is a condition in which a finger or thumb becomes stuck in a bent position and then suddenly straightens with a snap — similar to pulling and releasing a trigger. It occurs when the tendon sheath that allows the finger to glide becomes thickened or inflamed, restricting movement. This condition can cause pain, stiffness, and locking sensations, making it difficult to perform everyday tasks such as gripping or writing. At FormetricSurgery, trigger finger release is performed using refined surgical techniques to relieve the constriction and restore smooth, pain-free motion.

What Is the Procedure? -
What Is the Procedure? Trigger finger release is a minor surgical procedure performed under local anaesthesia. A small incision is made in the palm or at the base of the affected finger, allowing the surgeon to release the tight part of the tendon sheath so the tendon can move freely again. The wound is closed with fine sutures, and a light dressing is applied. The procedure usually takes 15–30 minutes, and you can return home the same day.

Who Is a Good Candidate? -
Who Is a Good Candidate? Trigger finger surgery may be recommended if you:
- Experience pain or clicking when moving a finger
- Have difficulty straightening or bending the finger
- Notice the finger locking or catching in position
- Did not improve with conservative treatments such as splinting or steroid injections
Your surgeon will evaluate your hand function and discuss the most suitable treatment plan for you.
-
Aftercare and Recovery -
Aftercare and Recovery After surgery, a small dressing will be applied to protect the incision. You can begin gentle finger movement almost immediately to prevent stiffness. Mild swelling or soreness is normal and usually resolves within a few days. Stitches are typically removed after 10–14 days, and most patients regain full motion and comfort within 2–4 weeks.
Frequently asked questions
Well-being starts here
-
Who is at higher risk of developing trigger finger? -
People who perform repetitive hand activities, individuals with diabetes or inflammatory conditions, and middle-aged adults are at higher risk.
-
Can trigger finger resolve without treatment? -
Mild cases may improve with rest, activity modification, and splinting, but persistent or severe cases often require medical treatment.
-
When is surgery recommended? -
Surgery is recommended when symptoms persist despite conservative treatment, or when the finger frequently locks and interferes with daily activities.
-
Can trigger finger recur after treatment? -
Recurrence is uncommon after successful treatment, especially following surgical release, although other fingers may develop the condition in the future.
