Comparing two low-dose radiotherapy schedules for chronic heel spur (plantar fasciitis)

Impact of Total Dose and Fractionation on Clinical Outcomes of Low-Dose Radiotherapy for Heel Spur Syndrome: Optimal Radiotherapy - Heel Spur Syndrome (ORHEELS) Randomized Clinical Trial

Not applicable Interventional Maria Sklodowska-Curie National Research Institute of Oncology · NCT07546240

This trial will test whether a standard 6 Gy daily low-dose radiotherapy schedule works as well as a lower 3 Gy twice-weekly schedule for people aged 40 and older with painful heel spurs (plantar fasciitis) that have not improved with other treatments.

What this trial studies

This is a prospective, randomized non-inferiority trial at the Maria Sklodowska-Curie National Research Institute of Oncology (Gliwice) comparing two low-dose radiotherapy fractionation schedules for chronic heel spur syndrome. One arm receives the Polish standard total dose of 6 Gy delivered in daily fractions, and the other receives a reduced total dose of 3 Gy delivered as 0.5 Gy fractions twice weekly. The trial will compare clinical outcomes and symptom control between the schedules while monitoring for signs of pro-inflammatory rebound and other adverse effects. The design aims to determine whether the lower cumulative dose can provide similar symptom relief while reducing long-term stochastic radiation risk.

Who should consider this trial

Good fit: Ideal candidates are people aged 40 or older with clinically confirmed painful heel spur (plantar fasciitis) lasting at least three months, who have not improved with orthopedic, physical, or analgesic treatments and have ZUBROD performance status 0–3.

Not a fit: Patients who previously had radiotherapy to the heel, recent local corticosteroid injections, prior trauma or surgery on the same foot, systemic collagen vascular disease, pregnancy or breastfeeding, or those unwilling to consent or follow up are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, patients could get similar pain relief with roughly half the cumulative radiation, lowering long-term cancer risk and treatment burden.

How similar studies have performed: Low-dose radiotherapy has been used in Europe for plantar fasciitis with reported anti-inflammatory benefits in smaller and non-randomized studies, but randomized comparisons of these specific fractionation schedules are limited.
