If a finger or thumb is catching, locking, or snapping painfully when you straighten it — especially first thing in the morning — there's a good chance the problem is trigger finger, also called stenosing tenosynovitis. It's one of the most common reasons people see a hand specialist, and it's also one of the most treatable. Most patients improve significantly with non-surgical care; for those who need it, the surgical release is a brief, reliable outpatient procedure.
Midwest Orthopaedics at Rush sees more than 13,000 hand, wrist, and elbow patients each year, treated by fellowship-trained hand specialists across seven Chicagoland locations. U.S. News & World Report ranks the practice as the #1 orthopedic program in Illinois and Indiana, and #8 nationally. This page covers what trigger finger is, why it happens, and the full ladder of treatment options — from a simple splint to a definitive surgical release.
Hand symptoms can have overlapping causes. This page is informational; a consultation with a hand specialist is the right path to a diagnosis and personalized treatment plan.
A flexor tendon runs the length of each finger, gliding back and forth through a series of protective tunnels — called pulleys — every time you make a fist. In trigger finger, the tendon or the lining around it becomes thickened or inflamed, usually at the A1 pulley near the base of the finger or thumb in the palm. The tendon no longer glides smoothly. Instead, it catches, snaps, and sometimes locks completely as it tries to pass through the narrow opening.
Common symptoms include:
Trigger finger is more common in:
In children, "pediatric trigger thumb" is a separate condition with its own treatment approach — see your surgeon for evaluation if you notice a young child's thumb that won't straighten.
Most cases of trigger finger respond to non-surgical care. Treatment generally begins with one or more of these approaches:
If a specific repetitive activity is clearly making symptoms worse, modifying or temporarily avoiding it gives the inflamed tendon a chance to settle down. This alone is rarely the full answer, but it's a useful piece of the plan.
A small splint that holds the affected finger in extension — usually worn at night — can help the inflammation calm down by stopping the catching motion during sleep. Splints are inexpensive and worth trying for milder, recent-onset cases. They typically work over several weeks.
Short courses of NSAIDs (oral or topical) can reduce inflammation around the tendon and pulley. As with any medication, talk with your physician about whether NSAIDs are appropriate given your other conditions and medications.
A targeted corticosteroid injection at the A1 pulley is the workhorse of non-surgical trigger finger treatment. Most patients experience significant improvement within days to a few weeks. Many cases are resolved by a single injection; some require a second. Repeated injections beyond two are usually not recommended, partly because the marginal benefit declines and partly because of small risks to the tendon itself with multiple injections in the same spot. Diabetic patients sometimes have less durable responses to injection — this is a known pattern and not a failure of the treatment.
Trigger finger release surgery is considered when:
Surgery for trigger finger has a long track record and a high success rate. The procedure is brief, performed under local anesthesia, and most patients return to normal activities within a few weeks.
The surgery itself is called an A1 pulley release. The surgeon makes a small incision — typically less than half an inch — in the palm at the base of the affected finger, exposes the A1 pulley (the band of tissue causing the catching), and divides it. Once released, the tendon can glide freely. The remaining pulleys hold the tendon close enough to the bone for normal function.
Key details patients usually ask about:
Most patients are pleased with how quick this recovery is. A general timeline:
Your surgeon's specific post-operative protocol may differ slightly, especially if you had multiple fingers released at the same procedure or have other hand conditions being treated.
Our hand specialists evaluate trigger finger like any other hand condition — diagnosis first, conservative care when appropriate, and surgery when it offers the most reliable path to lasting relief. For trigger finger specifically:
Our hand-and-wrist team includes Dr. Mark Cohen, Dr. John J. Fernandez, Dr. Nitin Goyal, Dr. Xavier Simcock, and Dr. Robert Wysocki. All are fellowship-trained in hand and upper extremity surgery.
Sometimes, especially if symptoms are mild and recent. More often, trigger finger persists or progresses without treatment — particularly if a clear catching or locking pattern has developed. Trying a splint and modifying aggravating activities is reasonable; if symptoms persist beyond a few weeks, a hand specialist visit is the right next step.
The injection itself is brief and uncomfortable but tolerable. A small needle delivers the medication near the A1 pulley in the palm. Most patients feel improvement starting within a few days, peaking over 1 to 2 weeks.
Schedule a visit promptly. A locked finger can usually be straightened — sometimes with a careful manual maneuver by the specialist, sometimes with the help of an injection, and sometimes definitively with a quick release. The longer a finger stays locked, the more secondary stiffness can develop, so don't wait it out.
Yes. Trigger finger in multiple fingers is common, particularly in diabetic patients and people with rheumatoid arthritis. Multiple fingers can be released in the same surgery if needed.
Most patients can drive within a few days, once they can grip the wheel without pain and aren't taking narcotic pain medication. Your surgeon will confirm based on your specific recovery.
