Trigger Finger

"When Your Finger Gets Stuck in First Gear!"

You reach for your paddle, curl your fingers around the grip, and then — nothing. One finger just sits there, bent, refusing to straighten without a little persuasion from your other hand.

Maybe it clicks. Maybe it pops. Maybe it locks up completely at the worst possible moment — like mid-dink.

Welcome to trigger finger. It's more common than you'd think, and the good news is it's usually very fixable.

What's going on?

Trigger finger — the medical term is stenosing flexor tenosynovitis — occurs when a finger's flexor tendon has difficulty gliding through a narrow pulley near the base of the finger.

The most commonly involved pulley is called the A1 pulley, located at the base of the finger in the palm. When the tendon or its surrounding sheath becomes irritated and thickened, it can no longer move smoothly through that tight space.

The result: a finger that catches, clicks, or locks — sometimes in a bent position that requires your other hand to straighten it out.

Think of it like a rope that's frayed trying to pass through a narrow ring. Eventually it gets stuck.

How do you recognize it?

Common symptoms include:

Clicking or popping when bending or straightening a finger.
A finger that catches or locks in a bent position.
Tenderness at the base of the finger in the palm.
Stiffness, especially in the morning.
Needing the other hand to straighten the finger.

Symptoms often start gradually and may be worse first thing in the morning or after periods of gripping.

In more advanced cases, the finger can become fixed in a bent position and may not straighten at all without intervention.

What actually works?

Activity modification

Reducing repetitive or forceful gripping can help calm irritation, particularly in mild cases.

Splinting

A splint worn at night — keeping the finger in a straight position — can reduce symptoms, especially when the condition is mild.

Corticosteroid injection

An injection near the tendon sheath is often effective and can provide lasting relief. It tends to be less predictable in patients with diabetes.

Surgery

A small procedure to release the A1 pulley is highly effective when symptoms persist or the finger becomes locked. It is typically performed as an outpatient procedure.

Treatment depends on symptom severity, how long the problem has been present, and individual factors such as diabetes or inflammatory conditions.

What about pickleball?

Repetitive gripping — exactly what you do every time you hold a paddle — is one of the recognized risk factors for trigger finger.

That doesn't mean pickleball caused your trigger finger, but it can certainly aggravate an existing problem.

If your finger is clicking or catching during play, try relaxing your grip between shots and see if symptoms improve. A lighter grip pressure goes a long way.

Your paddle grip should be firm enough to control the shot — not firm enough to strangle it.

When should you see a doctor?

Seek evaluation if your finger repeatedly locks or catches, if pain is interfering with daily activities or pickleball, or if you cannot fully bend or straighten the finger.

Prompt evaluation is especially warranted if the finger becomes fixed in one position, since a locked trigger finger is uncomfortable and can be more difficult to treat the longer it persists.

Dr. Engasser's Perspective

Dr. Mark C. Engasser, MD — Board-Certified Orthopedic Surgeon

"Trigger finger is a common and usually very treatable problem. In many cases, a simple injection or a small surgery can get your finger gliding again — so you can get back to gripping your paddle, not a stick shift!"
Trigger finger is one of the more satisfying conditions to treat because the results are usually quite good.
Patients often wait longer than they should, assuming the clicking or locking will resolve on its own. Sometimes it does — but when it doesn't, a straightforward injection or a brief outpatient procedure can make a dramatic difference.
Don't let a stuck finger keep you off the court.

Diagnosis, risk factors, surgery, recovery, and further reading

How is trigger finger diagnosed?

Diagnosis is usually clinical — based on the history and physical examination. The characteristic catching or locking of the finger, combined with tenderness at the A1 pulley, is generally sufficient to make the diagnosis.

Imaging is not typically required for straightforward cases, though ultrasound may occasionally be used to evaluate the tendon and sheath.

Who is more likely to develop it?

Trigger finger is more common in women and in individuals between the ages of 40 and 60. Associated conditions include diabetes, rheumatoid arthritis, and hypothyroidism. Repetitive gripping activities are a recognized contributing factor.

When is surgery considered?

Surgical release is typically recommended when symptoms persist despite one or more corticosteroid injections, when the finger is locked, or when the patient prefers a more definitive solution.

The procedure involves dividing the A1 pulley to allow the tendon to glide freely. It can be performed under local anesthesia as an outpatient procedure and is generally well tolerated.

What should you expect after treatment?

After a corticosteroid injection, improvement may occur within days to weeks. Some patients require more than one injection.

After surgical release, most patients recover well. Finger motion typically returns quickly, and return to activities such as pickleball is usually possible within a few weeks, depending on the individual.
