What is JointGlow?

Radiation used as an anti-inflammatory, not as a cancer treatment.

Low-dose radiotherapy — LDRT — uses the same equipment that treats cancer, at a tiny fraction of the dose. A course of radiation for a tumor might total 60 to 70 Gray. A full LDRT course for an arthritic joint totals about 3 to 5, delivered in six to ten brief sessions.

At that dose, radiation is not destroying tissue. It is changing the behavior of the inflammatory cells inside a painful joint — quieting the process that causes swelling, stiffness, and pain.

This is not experimental. European centers, particularly in Germany, have used LDRT for degenerative and inflammatory joint conditions for decades, in hundreds of thousands of patients.

Roughly a fifteenth of a cancer dose, spread across six to ten sessions of about 0.5 Gy each. The bars above are drawn to scale.

Founded by world leaders in low-dose radiotherapy

The physicians and physicists who built JointGlow are the ones publishing the evidence base for LDRT and training other centers in it. This is their primary field, not a service line added alongside cancer work.

The best protocol

Dose, fractionation, and interval are not improvised joint by joint. Each protocol is drawn from the published European experience and refined against our own outcomes, then applied consistently — so what worked for the last patient is what you receive.

The best delivery

Treatment runs on the Varian Edge® with HyperSight™ imaging — the same platform we use for radiosurgery. The joint is imaged and verified in position at every session, so the dose lands where it was planned and nowhere else.

The best minds planning your treatment

Every plan is designed by a radiation oncologist and a medical physicist and checked before the first session. Nothing is delegated to a template. For spine and hip in particular, that planning experience is what separates a good outcome from a wasted course.

Fewer inflammatory cells arrive

Low-dose radiation makes the blood vessel walls in the joint less sticky, so circulating white blood cells stop adhering and migrating into the tissue. The inflammatory traffic into the joint slows down.

The cells already there change behavior

Macrophages — the immune system's cleanup cells — exist in an inflammatory state and a repair state. LDRT pushes the population toward repair, and the joint's chemical environment shifts with it.

Pain signaling quiets

The molecules that sensitize nerve endings and drive swelling fall off. Patients usually describe it as the joint becoming quiet rather than numb — the ache recedes, and movement gets easier.

Consultation

A radiation oncologist reviews your imaging and history, confirms LDRT is appropriate for your joint, and answers questions. Nothing is treated this day.

Simulation

A short imaging session in the treatment position, so the beams can be shaped precisely around your anatomy. About thirty minutes.

Six to ten treatments

Typically twice a week over three to five weeks. You lie on the table, the machine moves around you, and it is over in a few minutes. No needles, no sedation, no recovery time.

Follow-up

Relief usually begins within one to two weeks of finishing and can continue improving for a few months. We check in at six to eight weeks. A second course is possible if needed.

The question everyone asks first.

Most people hear "radiation" and think of cancer treatment, and the side effects that come with it. The dose here is different enough that the comparison does not hold. There is no hair loss, no nausea, no fatigue of the kind chemotherapy or high-dose radiation causes.

Most patients report nothing at all during or after treatment. Occasionally there is mild, temporary skin warmth or a brief increase in joint soreness before relief sets in.

The theoretical concern with any radiation is long-term risk. At these doses it is very small, and it decreases with age — which is why LDRT is generally offered to older adults and considered more carefully in younger patients. Your radiation oncologist will discuss where you fall.

We check first

Before your consultation is scheduled, our team contacts your insurer, confirms your benefits, and determines whether prior authorization is required.

You get it in writing

If there is any out-of-pocket cost, you receive a written estimate before treatment begins. No one is surprised by a bill here.

Medicare & most major plans

We participate with Medicare and the major commercial plans in Central Florida. Bring your card to the consultation and we handle the rest.

If coverage is denied

We appeal, with the published evidence attached. If an appeal fails, we tell you plainly and discuss self-pay pricing rather than leaving you to figure it out.
