Trigger finger is stenosing tenosynovitis of a flexor tendon at the A1 pulley in the palm. A finger that catches, clicks, locks, or will not fully straighten is the classic presentation. Mild intermittent symptoms often improve with activity modification, splinting, or a single corticosteroid injection. Persistent locking, multiple affected fingers, or new symptoms in a diabetic or rheumatoid patient warrant prompt evaluation by a hand surgeon. This article covers the five signs that should prompt a specialist visit and what to expect at that appointment.
What Trigger Finger Actually Is
The flexor tendons that bend your fingers run from the forearm through a series of tunnels in the hand and fingers called pulleys. The A1 pulley sits in the palm at the base of each finger. In trigger finger, the flexor tendon or the sheath surrounding it becomes thickened, and the tendon no longer glides smoothly through the narrowed A1 pulley. Each time the tendon forces its way through, it catches and then releases, producing the characteristic click and, in advanced cases, a fully locked finger.
Trigger finger most commonly affects the thumb, ring, and middle fingers. It is more frequent in women, in patients with diabetes or rheumatoid arthritis, in those with hypothyroidism, and in workers performing repetitive gripping. It is a mechanical problem at a specific, identifiable anatomic site, not a systemic disease.
Five Signs You Should See a Hand Surgeon
Many mild cases of trigger finger improve on their own or with simple measures. The following signs suggest the condition will not resolve without targeted treatment.
- A finger that locks in a bent position. If you have to pull the finger straight with your other hand, the pulley is meaningfully narrowed and a procedural treatment is typically needed.
- Catching that has not improved after two to four weeks of activity modification, anti-inflammatory medication, or over-the-counter splinting. Persistence at this point predicts persistence without intervention.
- A tender, palpable nodule in the palm at the base of the affected finger. This is the thickened flexor tendon. Its presence makes the diagnosis straightforward and the treatment well defined.
- More than one finger is involved. Multiple trigger digits are common in diabetic patients and in those with systemic conditions. They can be treated together in a single procedure.
- Diabetes, rheumatoid arthritis, or hypothyroidism with new trigger finger symptoms. These patients respond less predictably to conservative care and benefit from earlier specialist evaluation.

What Happens at a Hand Surgery Evaluation
Trigger finger is a clinical diagnosis. Dr. Loredo examines the palm and palpates the A1 pulley region. Active finger motion typically reproduces the catching or locking that the patient describes. The examination takes a few minutes and does not involve imaging in most cases. X-rays, ultrasound, or MRI are occasionally helpful, but the standard presentation is confirmed on physical exam alone.
The visit also includes a discussion of your medical history, which fingers are affected, how long symptoms have been present, and what has already been tried. Treatment recommendations are made the same visit.

Treatment Options and What to Expect
Treatment follows a stepwise approach.
- Activity modification and splinting. A simple splint that holds the affected finger straight at night can reduce morning catching. Adjustments to grip-intensive activities give the tendon time to calm down.
- Corticosteroid injection into the flexor tendon sheath. A single injection resolves symptoms in roughly 60 percent of first-time, non-diabetic cases. Diabetic patients respond less predictably. Injection takes less than a minute in the office and discomfort is brief.
- Surgical release of the A1 pulley. When injection fails or symptoms recur, release is the definitive treatment. The procedure takes about 10 to 15 minutes under local anesthesia. Most patients use the hand lightly the same day and return to desk work within a few days. Multiple fingers can be released in a single visit.
Recurrence after a complete release is uncommon. Complications are uncommon in experienced hands.

Frequently Asked Questions
Is trigger finger a tumor?
No. Trigger finger is not a tumor. It is stenosing tenosynovitis, a thickening of the flexor tendon or its sheath at the A1 pulley in the palm. The palpable nodule that patients feel is the irritated tendon, not a mass. Imaging is usually not necessary to make the diagnosis.
Will a cortisone shot fix trigger finger?
A single corticosteroid injection resolves trigger finger in roughly 60 percent of first-time, non-diabetic cases. Diabetic patients respond less predictably. When symptoms return after one or two injections, surgical release is the definitive treatment and has a very high success rate.
How long is trigger finger release surgery and the recovery?
The procedure takes about 10 to 15 minutes and is performed under local anesthesia. Most patients use the hand lightly the same day, return to desk work within a few days, and resume heavier activity within two to four weeks.
Can multiple trigger fingers be treated at once?
Yes. Multiple trigger digits are commonly released in a single visit when clinically appropriate. This saves the patient from multiple recovery periods and is well tolerated.
Do I need a referral to see a hand surgeon for trigger finger?
Not always. Many insurance plans allow self-referral to a specialist. Our office can verify your plan when you call. If your plan requires a primary care referral, we can coordinate that with you before your appointment.
