The Effect of USG-Guided Coccygeal Nerve Block on Sacrococcygeal and/or Intercoccygeal Joint Injection for Coccydynia

Coccydynia refers to a significant pain, that does not radiate, in and around the coccyx region. This symptom is typically worsen while sitting, especially on hard surfaces, standing up from sitting position and standing for long time. The steroid and anesthetic injection to the sacrococcygeal, intercoccygeal joints and impar ganglions are the most commonly cited second line management option in the literatures for refractor cases. The coccygeal nerve blockade or radiofrequency ablation is also used for coccydynia especially for traumatic cases. The aim of the study is; to evaluate the efficacy of ultrasound-guided sacrococcygeal and/or intercoccygeal joint injection in coccydynia and to investigate whether coccygeal nerve blockade has an additional contribution to this treatment.
