What Is Tennis Elbow?
Lateral epicondylitis is a chronic overuse condition of the common extensor tendon at the lateral epicondyle of the elbow, most often affecting the extensor carpi radialis brevis (ECRB) at its bony attachment. The condition develops from repetitive wrist extension and gripping — racquet sports, manual trades, keyboard work, lifting. Pain is felt on the outside of the elbow, often radiating into the forearm, and is worsened by gripping, lifting, or twisting motions.
Despite the name, fewer than 1 in 10 patients with tennis elbow play tennis. The underlying pathology is tendon degeneration ("tendinosis"), not true inflammation, which is why anti-inflammatories often disappoint.
How LDRT Treats Tennis Elbow
LDRT delivers a precisely calibrated, very low dose of X-rays to the lateral epicondyle and the surrounding tendon insertion. The mechanism is anti-inflammatory at the cellular level — modulating macrophage polarization, reducing pro-inflammatory cytokines, and quieting the chronic immune response that keeps the tendon from healing. Treatment is non-invasive and painless.
Published outcomes for LDRT in chronic lateral epicondylitis are part of the DEGRO 2018 guidelines, with response rates in the 70-80% range across multiple European trials. The dose is 10 to 25 times lower than the dose used for cancer treatment.
Who Is a Candidate for LDRT?
- Pain on the outside of your elbow for 6+ months
- Cortisone injections that wore off or stopped helping
- Physical therapy, eccentric exercises, or counter-force bracing without lasting improvement
- PRP injections that did not deliver the results you hoped for
- You want to avoid tennis elbow surgery (tendon release / ECRB debridement)
At Heelex Medical, we treat the chronic inflammatory environment that keeps the tendon from healing — so the elbow can finally settle.
What to Expect
Your care begins with a one-on-one consultation where we evaluate elbow function, review imaging, and discuss your treatment history. If LDRT is right for you, treatment typically involves 6 to 8 weekday sessions. Each session is quick and painless. There are no needles, no anesthesia, and no activity restrictions between sessions. Many patients notice gradual improvements in pain with gripping and lifting in the weeks following their treatment course.
