Key result
Pulse radiofrequency neurotomy significantly reduced VAS pain scores at 6 months compared to a single dose of corticosteroid injection in patients with chronic coccydynia.
Why the study?
Ganglion impar block shows promise for coccydynia, prompting a comparison of outcomes between a single-dose corticosteroid injection and pulse radiofrequency neurotomy.
Does pulse radiofrequency neurotomy improve pain and functional scores compared to corticosteroid injection in patients with chronic coccydynia?

Does pulse radiofrequency neurotomy improve pain and functional scores compared to corticosteroid injection in patients with chronic coccydynia?
Absolute Event Rate: 0.4% vs 1.3%
p-value: p=<0.05
Pulse radiofrequency neurotomy provides superior pain relief and functional improvement at 6 months compared to a single dose of corticosteroid for the treatment of chronic coccydynia.
PRF may yield superior 6-month pain and function scores versus corticosteroid block in coccydynia; leaves open need for RCTs to guide practice.

Emet et al. (2023) conducted a cohort in Coccydynia (n=26). Pulse radiofrequency neurotomy vs. Corticosteroid injection was evaluated on Visual Analogue Scale (VAS) score at 6 months (p=<0.05). Pulse radiofrequency neurotomy significantly reduced VAS pain scores at 6 months compared to a single dose of corticosteroid injection in patients with chronic coccydynia.
