We recently read the interesting article entitled "Coccygectomy as a surgical option in the treatment of chronic traumatic coccygodynia: a single-center experience and literature review" by Antoniadis et al.  which touches on an underrated topic in neurosurgical practice.
Periosteal preservation and closure during the coccygectomy procedure have been found to be related to a low risk of infection . Although Antoniadis et al. did not mention this in their case series, the information should be presented in a literature review.
Additionally, some other treatment options, such as caudal epidural pulsed radiofrequency treatment, have been found to be efficient after unsuccessful non-surgical and surgical treatment modalities in the treatment of coccygodynia and should also be mentioned in the article. Atim et al.  achieved excellent and good results in 81% of cases treated with caudal epidural pulsed radiofrequency.
We expect that these small additions will increase the value of Antoniadis' article.
