Trigger Finger Treatment in Scottsdale & the East Valley: When Do You Need Surgery?

If your finger catches, locks, or clicks when you bend it—or if you have to physically straighten it with your other hand—you may have trigger finger. It’s one of the most common conditions I treat as a hand surgeon serving Scottsdale, Mesa, Chandler, Gilbert, and the greater Phoenix area.

The medical term is stenosing tenosynovitis, and while the name sounds complicated, the condition is straightforward: the tendon that bends your finger gets caught on a thickened pulley at the base of the finger, causing painful clicking, locking, or both.

What Causes Trigger Finger?

Each finger has a series of pulleys—small bands of tissue that hold the flexor tendon close to the bone, like the guides on a fishing rod. The A1 pulley, located at the base of the finger in the palm, is where trigger finger occurs. When this pulley becomes thickened or inflamed, the tendon can no longer glide smoothly through it. The result is catching, clicking, or locking of the finger.

Risk factors include:

• Diabetes—significantly increases the risk and can make the condition harder to treat

• Repetitive gripping activities (tools, golf clubs, gardening)

• Rheumatoid arthritis and other inflammatory conditions

• Age over 40, with women affected more often than men

• Having carpal tunnel syndrome (the two conditions frequently coexist)
  

Trigger Finger Symptoms

Patients across the East Valley describe trigger finger symptoms in remarkably consistent ways:

• A painful click or pop when bending or straightening the finger

• The finger locking in a bent position, requiring the other hand to straighten it

• Stiffness and pain at the base of the finger, especially in the morning

• A tender nodule or bump in the palm at the base of the affected finger

• In severe cases, the finger becomes locked and cannot be straightened at all

Trigger finger can affect any digit, including the thumb (trigger thumb). Multiple fingers can be involved simultaneously, particularly in patients with diabetes.

Non-Surgical Treatment Options

For many patients, especially those with mild to moderate symptoms, non-surgical treatment is effective:

Activity Modification and Splinting

Reducing repetitive gripping and wearing a splint that keeps the finger in a straight position (particularly at night) can help reduce inflammation and catching.

Corticosteroid Injection

A steroid injection into the tendon sheath at the A1 pulley is the most common first-line treatment. It reduces inflammation and allows the tendon to glide freely again. Studies show that a single injection resolves symptoms in about 60–70% of patients. A second injection can be tried if symptoms recur. However, success rates are lower in patients with diabetes or those who have had symptoms for a long time.

When Is Trigger Finger Surgery Needed?

I recommend trigger finger release surgery when:

• Symptoms persist after one or two steroid injections

• The finger is locked and cannot be straightened

• Symptoms are severe or significantly limiting daily function

• The patient prefers a definitive solution over repeated injections
  

What Happens During Trigger Finger Release Surgery?

Trigger finger release is a quick outpatient procedure performed under local anesthesia. You’re awake but the hand is completely numb. The procedure takes approximately 5–10 minutes.

For all fingers (index through small finger), I make a small longitudinal incision in the palm over the A1 pulley. For the thumb, I use a transverse incision. Through this incision, I directly visualize and divide the A1 pulley, which immediately releases the tendon and eliminates the catching. The skin is closed with a few sutures.

The success rate of trigger finger release is extremely high—greater than 95%—with recurrence being very rare.

Recovery After Trigger Finger Surgery

Recovery is straightforward:

• Immediately after surgery: You can and should move your finger right away. The catching is gone immediately.

• Days 1–3: Mild soreness and swelling. Over-the-counter pain medication is usually sufficient.

• Days 10–14: Sutures are removed. Most patients return to normal activities.

• Weeks 4–6: Full grip strength returns. Some mild palm tenderness may linger but resolves.

Formal physical therapy is rarely needed. I provide a simple home exercise program to keep the finger moving.

Frequently Asked Questions About Trigger Finger

Can trigger finger heal on its own?

Mild cases occasionally resolve with rest and activity modification, but most cases either persist or worsen over time. If symptoms last more than a few weeks, it’s worth seeing a hand surgeon.

Is trigger finger release surgery painful?

The surgery itself is painless due to local anesthesia. Post-operative discomfort is mild and typically managed with over-the-counter medications for a few days.

Can trigger finger come back after surgery?

Recurrence after surgical release is very rare—less than 3%. The A1 pulley does not need to regenerate for normal finger function.

I have trigger finger in multiple fingers. Can they all be fixed at once?

Yes. Multiple trigger finger releases can be performed in the same procedure. This is common, particularly in patients with diabetes.
