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 Surprise, 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.

Frequently Asked Questions: Trigger Finger & LDRT
Is radiation therapy safe for trigger finger? +
Yes. The dose is roughly 10 to 25 times lower than the dose used to treat cancer and is targeted to only the affected finger. Decades of use in Europe have not shown an increased cancer risk at these low doses, and side effects are rare — occasionally mild, temporary skin redness.
Can low-dose radiation therapy treat trigger finger without surgery? +
It is aimed at patients who want to avoid a surgical release or aren't good surgical candidates. LDRT calms the inflammation around the tendon that causes the catching and locking. It is painless, needs no anesthesia or downtime, and doesn't rule out a surgical release later if you ever need one. Individual results vary.
What if splinting and a cortisone injection haven't fixed my trigger finger? +
That is exactly who LDRT is for. When a splint and one or two steroid injections haven't stopped the catching, low-dose radiation therapy targets the underlying inflammation around the tendon — a non-surgical option worth understanding before an A1 pulley release.
Do I need a referral? +
No. You can call us directly. If you have an orthopedic surgeon, primary care physician, or rheumatologist, we coordinate with them.
Does it hurt? +
No. You feel nothing during treatment. No needle, no injection, no anesthesia.
Are there side effects? +
Rare. Some patients notice mild, temporary skin redness. No systemic side effects.
Will it cause cancer? +
The dose used for benign conditions is 10 to 25 times lower than the dose used to treat cancer. Long-term studies in Germany — where LDRT has been used for decades — have not shown an increased cancer risk at these low doses. We do not treat patients under 40 except in specific circumstances.
How quickly will I feel better? +
Most patients begin noticing relief between 6 and 12 weeks after their final session. About 70% report meaningful improvement.
How long does relief last? +
Typically 12 to 24 months. A second course can be given if symptoms return.
What if it doesn't work for me? +
Most patients respond well — and if your consultation shows you're not a strong candidate, we'll tell you up front, before you've spent a dime. LDRT also never closes any doors: every other option, including surgery, stays open to you.
Is it covered by insurance? +
Most major insurance is accepted, including Medicare and major commercial plans. Our office handles all insurance pre-authorization.
How many sessions will I need? +
Most benign musculoskeletal conditions require 6 to 8 weekday sessions, scheduled on consecutive business days so you complete a full course in under two weeks. Each session takes about 15 minutes. Some skin and fibrotic conditions follow different protocols — your consultation will clarify what fits your situation.
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.
