Anococcygeal Nerve Radiofrequency Ablation in Chronic Coccydynia: A Conservative Approach in a Refractory Case

• Coccydynia common regional pain condition associated with reduced quality of life in severe and chronic cases. Women and obesity  are at risk factors

• Common etiologies include external trauma, internal trauma during childbirth, chronic repetitive injury, and degenerative joint disease

• Coccyx has role in weight-bearing while seated, pelvic floor support, anus support, and voluntary bowel control. Coccygeal plexus and anococcygeal nerve course along the coccyx, placing them at risk from regional injury/inflammation. Extensive regional anatomic variability, including in quantity of fused segments forming coccyx, presence and morphology of intercoccygeal disc-like structures, and type of sacrococcygeal articulation present

• Considerable variability results in similar etiological variability, and consequently management approaches should be individualized to specific lesions and presenting symptoms
