The coccyx bone is the lowest bone in the spine. Fractures of the coccyx bone can occur after falls and sometimes after childbirth. Both fractures and diseases related to the genital tract or anus can cause coccygeal pain (coccidynia, cocsalgia).

Diagnosis

In patients with coccidynia magnetic resonance imaging (MRI) is performed to evaluate the condition of the coccyx after examination. These patients may sometimes require computed tomography (CT) imaging to evaluate bone structures.

Treatment

In the treatment of coccydynia, an injection is given in and around the joint where the coccyx articulates with the sacrum and around the ganglion impar. The purpose of the injection is to administer local anesthetic and corticosteroid medication. Sometimes, in more widespread, persistent pain and pelvic pain, impar ganglion blockade is performed in front of the sacrum and coccyx bones. The medication is expected to relieve the pain for a certain period of time or permanently.

For the same purpose, radiofrequency can also be used. This is based on the principle that a probe tip generates heat between 40 and 80 °C with radio waves to produce an analgesic effect (pain relief). This destroys the pain nerve around the coccyx and provides pain relief.
