About

The aim of this study is to evaluate feasibility, reliability and short term effectiveness of ganglion impar block with ultrasound in patients with chronic coccygodinia.

Full description

Ganglion impar blocks have long been used for coccydynia, either with a landmark-based technique or fluoroscopic guidance. With the growing use of ultrasound, ultrasound-guided ganglion impar block has become a viable alternative.

Despite its frequent use in clinical practice, ultrasound has limitations in visualizing structures behind the bone, while fluoroscopy remains the gold standard. Further research is needed to evaluate its feasibility, safety, and efficacy.

This study primarily aims to assess the feasibility and safety of ultrasound-guided ganglion impar block in coccydynia. Additionally, it will examine its short-term (1-month) efficacy.
