Background and Aims:

Coccygeal pain (tailbone pain) is a rare but painful disorder characterized by axial coccygeal pain, which is typically exacerbated by pressure and can occur from local trauma or a tumor. The pain can travel into the lower buttocks and occasionally into the groin. The aim of this study is to evaluate the efficacy of coccygeal radiofrequency (RF) and steroid injections in the management of coccydynia.


15 patients were evaluated and diagnosed at the Pain & Headache Center, International Medical Center, KSA, with coccydynia, who failed treatment with steroids injection. They all underwent coccygeal RF plus injection of 20 mg of Depo-Medrol diluted in 2 ml of Heavy Marcain at each level. The RF was applied to the joints, with the following settings: temperature: 90C for 90 sec; then for 60 sec. Patients were followed up to 2 years period. Inclusive criteria: 10 females and 5 males; patients mean age was 52 years.


An average improvement of 75%, according to the numeric pain scale, was seen in patients who were treated with coccygeal RF and sustained for a period of at least 9 months.


Patients with coccygeal pain responded very well to coccygeal RF plus steroid injections and the benefit lasted for more than 9 months.
