Effect of Additional Sural Nerve PRF in Chronic Heel Pain

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.
