What Is Trigger Finger?

Trigger finger, known medically as stenosing tenosynovitis, occurs when inflammation narrows the sheath surrounding a finger tendon. This narrowing prevents the tendon from gliding smoothly, causing the finger to catch, lock, or snap when you try to bend or straighten it. The condition most commonly affects the ring finger and thumb but can occur in any finger.

Symptoms typically include stiffness (especially in the morning), a clicking or popping sensation when moving the finger, tenderness at the base of the affected finger, and in severe cases, the finger becoming locked in a bent position.

Trigger finger is frequently treated with splinting, anti-inflammatory medications, cortisone injections, and trigger finger release surgery. Cortisone injections are effective for some patients but often need to be repeated, and their effectiveness can diminish over time. Surgery, while generally successful, involves cutting the tendon sheath and carries risks including infection, stiffness, and incomplete resolution.

How LDRT Treats Trigger Finger

LDRT addresses trigger finger by reducing the chronic inflammation that causes the tendon sheath to thicken and constrict. A carefully calibrated, low-energy dose of radiation is directed at the base of the affected finger where the tendon sheath is inflamed.

This targeted approach stimulates the body's own anti-inflammatory mechanisms, gradually reducing swelling and restoring smooth tendon movement. The treatment is entirely external, involves no injection or incision, and is completed in minutes per session.

Because LDRT works at the biological level rather than simply suppressing symptoms, the results tend to be more durable than repeated cortisone injections.

Who Is a Candidate for LDRT?

Cortisone injections have failed, worn off, or stopped working after multiple rounds
Splinting has not resolved the catching or locking
You had trigger finger release surgery but the problem returned
You prefer to avoid surgery due to medical reasons or personal preference
You have trigger finger in multiple fingers and want a non-surgical option

At Heelex Medical, we regularly treat patients who assumed they had no choice but to accept the condition or undergo surgery. LDRT changes that equation.

What to Expect

After an initial consultation to review your condition and treatment history, we design a personalized LDRT plan. Treatment typically consists of 6 to 8 weekday sessions. Sessions are brief and painless. You sit comfortably while the treatment is delivered to the affected area. There is no anesthesia, no bandaging, and no downtime. You can use your hand normally between sessions. Improvement is gradual, with most patients experiencing reduced catching and improved finger movement in the weeks following treatment.

Working With Your Care Team

Your hand surgeon or orthopedic hand specialist knows your history and your options better than anyone, along with the hand therapist on your care team. We don't replace them, and we wouldn't want to. We're a resource for them — for patients who have worked through the usual steps and want a non-surgical, drug-free option before considering surgery. You stay in their care: we treat only what's referred, keep your doctors informed, and refer you back to them. We're not here to take anyone's patients.

Is Low-Dose Radiation Therapy safe?

The dose used for benign conditions is a small fraction of cancer-treatment radiation — roughly 10–25× lower — delivered in a few short sessions. Low-dose radiation therapy for benign disease has decades of clinical use, and side effects are uncommon and typically mild.

Every treatment plan is prepared by a board-certified medical physicist and reviewed by a licensed physician. Whether it's the right option for you — and any personal considerations — is decided together during your consultation.
