Overview
This observational study aims to compare the effectiveness of pulsed radiofrequency (PRF) treatment applied to the posterior tibial nerve alone versus PRF applied to both the posterior tibial and sural nerves in patients with chronic plantar heel pain. Outcomes will be assessed using the Visual Analog Scale (VAS) and the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score at baseline, 1 month, and 3 months after treatment.
Description
Chronic plantar heel pain is a common condition frequently managed with interventional pain procedures. In routine clinical practice, pulsed radiofrequency (PRF) is commonly applied to the posterior tibial nerve under ultrasound guidance. In selected patients, PRF is additionally applied to the sural nerve based on clinical judgment.
This observational study includes patients who have already undergone PRF treatment as part of standard care in the Algology Clinic. Patients will not be randomized, and no modification to treatment plans will be made for study purposes. Patients will be divided into two groups: those who received PRF to the posterior tibial nerve alone, and those who received PRF to both the posterior tibial and sural nerves. Pain intensity and functional outcomes will be retrospectively evaluated and compared between groups.
