This prospective single-arm pilot interventional study aims to evaluate the effectiveness of ultrasound-guided radiofrequency ablation of the inferior calcaneal nerve in patients with chronic heel pain refractory to conservative treatments. Patients with plantar fasciitis or calcaneal spur who have not responded to multiple treatment modalities, including exercise, nonsteroidal anti-inflammatory drugs, orthotics, extracorporeal shockwave therapy, and corticosteroid injections, will be included. The procedure will be performed under ultrasound guidance. Pain intensity, functional status, and patient satisfaction will be assessed at baseline and at 1 and 3 months after the intervention. The primary outcome is treatment success, defined as a ≥50% reduction in pain intensity at 1 month compared to baseline.
