In 18 Patients with symptomatic coccygodynia due to malignant diseases 7 sacral rhizotomies and 11 intrathecal injections of Phenol had been effected. The high percentage of good results and the low rate of complications indicates in the opinion of the author that these methods are worth a trial in such cases, where otherwise only bilateral cordotomy with a much higher incidence of complications may be able to obtain pain relief.
