Jason A.T. Woon
as a highly-motivated medical researcher, I have multiple publications on the coccygeal anatomy. A recent doctoral graduate from the University of Otago, with a thesis awarded an exceptional grade (top 10%) titled ‘Clinical Anatomy of the Human Coccyx’, a detailed investigation into the anatomy of the coccyx using dissection, radiography, and histology was reported. The results have been published in several high-quality journals and aims to fill gaps in the existing knowledge of the coccyx, particularly in relation to the coccygeal plexus, sacrococcygeal intercornual region, and the bony morphology and morphometry of the coccyx. As a senior medical student, my hope is to continue to develop my research skills, explore new avenues and contribute to the scientific community.

Elif Gürkan, MD, Istanbul
As a Physical Medicine and Rehabilitation specialist in my country, I am mostly practising treatment modalities for pain due to spinal disorders. In the year of 2000, I visited the clinic of Dr. Jean Yves Maigne in Paris for learning manual medicine. In the meanwhile, he mentioned me about dynamic x-rays and intradiscal injections for coccydynia. Then I was very interested in this complex pain syndrome in musculoskeletal medicine. After then, I had the chance to meet more than 1000 patients with coccydynia. In most of the cases dynamic x-rays and magnetic resonance imaging were showing the pain source. What really interesting was that a very small number of patients had a psychosomatic basis as believed for many years. I think dynamic x-rays have been a very helpful answer to understand the reason underlying coccydynia in %75 of patients and treating patients with intradiscal injections have been really successful. However, this region keeps to be mysterious in terms of cause of the pain and the cause of recurrence of the pain after treatment in a certain group of patients. So I would like to work more on anatomy, cause, manual treatment options, different medical alternatives and injections for coccydynia.

Dr. Thibault Riant
Former anaesthetist. Pain physician for 15 years: Consultations, CT-guided and US infiltrations including coccyx, IMPAR ganglia…I work in a pain unit which contributes to the Nantes Federative Pelvic Pain Centre. This centre regroups two pain units: public and private. There are also private physiotherapists and osteopaths.During a long time, our main topic was only perineal neuralgia (pudendal, cluneal, obturator). For few years now, we have driven this experience further enlarging our practice with new modalities including coccygodynia, vestibulodynia, pelvic hypersensitization and chronic post-operative pain.We see around 1500 new patients each year who are suffering from the “pelvic” area. We organize three multidisciplinary consultations by month. The professionals invited are: pain physicians, gynaecologists, urologists, psychologists, physiotherapists, osteopaths. The first consultation includes patients with perineal neuralgia, coccygodynia. The second one is for patients with pelvic pain and urologic diseases. Finally, the last one is open to patients with pelvic pain and gynaecologic diseases.

From this period, the interest for the Pudendal neuralgia leads to a better knowledge of the other causes of chronic pelvic and perineal pain : endometriosis, adenomyosis, other pelvic and perineal neuralgias, interstitial cystitis, vulvodynias and vestibulitis, uretrals and ano-rectals syndromes, myo-fascial syndromes. The other main working pole is the treatment and surgical repair of the post-trauma, post-operative, post-pelvic cancer treatments and post-delivery, pelvi-perineal lesions.
