Adding sural nerve pulsed radiofrequency to posterior tibial nerve PRF for chronic heel pain

Official title: Does Targeting the Sural Nerve in Addition to the Posterior Tibial Nerve Increase the Effectiveness of Pulsed Radiofrequency Treatment in Chronic Plantar Heel Pain?

Run by Diskapi Teaching and Research Hospital · NCT07383558 · Data updated 2026-11-12

This project tests whether giving pulsed radiofrequency to the sural nerve in addition to the usual posterior tibial nerve PRF reduces pain and improves foot function in adults with chronic plantar heel pain.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–65 with chronic plantar heel pain who had baseline VAS scores above 5 and received PRF as part of standard care would be the ideal candidates.

Probably not a fit

People with alternative causes of heel pain such as recent foot fracture or tumor, those who are pregnant, on antiplatelet therapy or with coagulopathy, or those with low baseline pain are unlikely to gain additional benefit from adding sural nerve PRF.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is an observational, retrospective comparison of patients who received pulsed radiofrequency (PRF) to the posterior tibial nerve alone versus those who also received PRF to the sural nerve as part of routine care. Outcomes include pain measured by the Visual Analog Scale (VAS) and function measured by the AOFAS hindfoot score at baseline, 1 month, and 3 months after treatment. Patients were not randomized and received treatments based on clinical judgment, with data collected from clinic records. The analysis will compare changes in pain and function between the two groups over the follow-up period.

Why it matters

Potential benefit: If adding sural nerve PRF provides extra relief, patients could experience greater pain reduction and improved foot function than with posterior tibial nerve PRF alone.

How similar studies have gone: There are prior reports of posterior tibial nerve PRF helping heel pain, but using an added sural nerve PRF is less studied and remains relatively novel.
