Hand Surgery
Trigger Finger
“When your finger refuses to let go — even digits have commitment issues.”
What is Trigger Finger?
Trigger finger (also called Stenosing Tenosynovitis) is a condition where a finger gets stuck in a bent position and then suddenly snaps straight, like pulling and releasing a trigger.
It is caused by inflammation or thickening of the tendon sheath in the finger. This prevents smooth gliding of the flexor tendon through its tunnel (the pulley).
It is commonly seen in people who perform repetitive gripping (e.g., manual labor, gardening). It is more frequent in diabetics and rheumatoid arthritis patients.
Symptoms include catching or locking sensation when bending or straightening the finger. A palpable nodule may be felt at the base of the finger. Pain or tenderness at the base of the finger (palm side) may be felt in early cases. In severe cases, the finger may lock completely.
Trigger Thumb is when this condition affects the thumb. It's causes and symptoms are the same as for trigger finger.
Causes of Trigger Finger
Trigger finger occurs due to:
-
thickening of the tendon sheath.
-
repetitive hand use or gripping.
-
diabetes.
-
rheumatoid arthritis.
-
hand strain or overuse.
Trigger Finger in Children
It is common in middle-aged adults but can also occur in children. When seen in children, it is usually not treated until the child reaches 1 year of age, primarily because chances are high it will heal spontaneously, without any treatment.
Treatment of Trigger Finger
1. Non-Surgical Treatment
-
Rest and activity modification: Avoid repetitive gripping or strain.
-
Splinting: Keeps the finger straight to reduce irritation.
-
Medications: Anti-inflammatory drugs (NSAIDs) for pain and swelling.
-
Steroid injections: Reduce tendon sheath inflammation — often very effective.
2. Surgical Treatment
-
Percutaneous release: A needle is used to release the tight pulley under local anesthesia.
-
Open surgical release: A small incision is made to cut the A1 pulley and free the tendon. This is usually done if non-surgical measures fail.
Diagnosis
Diagnosis is usually clinical and involves:
-
detailed hand examination.
-
assessment of finger movement.
-
ruling out other hand conditions.
Imaging is rarely required.
Recovery After Trigger Finger Surgery
-
immediate finger movement encouraged.
-
pain relief is usually rapid.
-
return to daily activities within days.
-
stitches removed in 10–14 days.
Complications of Trigger Finger Treatment
While most patients recover fully, a few complications can occur — particularly after surgical release or in severe, long-standing cases:
-
Incomplete release or recurrence:
-
The tendon may still catch or lock if the pulley isn’t fully released or if inflammation returns.
-
More likely in diabetics or those with multiple affected fingers.
-
-
Stiffness and reduced motion:
-
Scar tissue or prolonged preoperative locking can limit smooth flexion and extension even after surgery.
-
Regular finger exercises and early mobilization help prevent this.
-
-
Tender or hypertrophic scar:
-
A small lump or soreness at the incision site is common initially and usually settles over time.
-
-
Nerve injury:
-
Tiny digital nerves lie close to the pulley and can be irritated or rarely damaged during surgery, leading to numbness or tingling.
-
-
Tendon injury or bowstringing:
-
Very rare, but if too much of the pulley is cut, the tendon may bow outward during movement.
-
-
Infection or delayed wound healing:
-
Uncommon, but can occur especially in patients with diabetes or poor skin condition.
-
-
Recurrence in other fingers:
-
Sometimes, the condition appears later in a different finger due to the same underlying cause.
