The effectiveness of conventional radiofrequency ablation for chronic plantar heel pain due to heel spur.

Objectives: The purpose of this study was to investigate the effectiveness of conventional radiofrequency (CRF) ablation treatment on chronic plantar heel pain due to heel spur.

Methods: A total of 20 patients with heel spur who did not respond to conservative treatments were recruited for the study. Under fluoroscopy guidance, CRF was performed to three points at the top, above, and below the heel spur in the longitudinal plane of the foot. Pain intensity, the pressure pain threshold (PPT), and functional status were assessed using a visual analog scale (VAS), pressure algometers, and the Foot Function Index (FFI). All measurements were taken before the procedure, as well as 1, 3, and 6 months following the procedure.

Results: CRF was applied to 20 patients - 16 (80%) females and 4 (20%) males. Their mean age was 51.40+-8.10 years, the mean body mass index was 33.80+-5.47 kg/m2, the mean duration of symptoms was 18.30+-9.02 months, and pes planus was present in 5 patients (25%). A statistically significant decrease was observed in VAS score and PPT and FFI measurements at the 1st, 3rd, and 6th month following CRF compared to before CRF (p<0.001).

Conclusion: CRF is an effective, safe, minimally invasive method to reduce pain severity in patients with chronic heel pain due to heel spur in the short (0-3 months) and intermediate term (3-6 months).
