| Name = Ganglion impar | Latin = ganglion impar | Image = | Caption = | Image2 = | Caption2 = | System = | Precursor = }} The pelvic portion of each sympathetic trunk is situated in front of the sacrum, medial to the anterior sacral foramina. It consists of four or five small sacral ganglia, connected together by interganglionic cords, and continuous above with the abdominal portion. Below, the two pelvic sympathetic trunks converge, and end on the front of the coccyx in a small ganglion, the ganglion impar, also known as azygos [1] or ganglion of Walther. Clinical significancePhysicians at New Jersey Medical School specializing in physical medicine and rehabilitation have published that sometimes even just a single local nerve block injection at the ganglion impar can give complete relief of coccydynia (tailbone or coccyx pain), when performed under fluoroscopic guidance.[2] References{{Gray's}}1. ^{{cite web|last1=Erasmus Wilson|first1=William James|title=Practical and surgical anatomy|url=https://books.google.co.uk/books?id=bGUEAAAAQAAJ&pg=PA431&lpg=PA431&dq=ganglion+impar+-+azygos&source=bl&ots=NiCVtQO19d&sig=DNZ9WG9cqZGDgNCsw4RWNsW_dfw&hl=en&sa=X&ved=0ahUKEwjlzaLd3ObVAhWHJsAKHQ65A_kQ6AEISTAJ#v=onepage&q=ganglion%20impar%20-%20azygos&f=false|language=en|date=1838}} 2. ^{{cite journal |vauthors=Foye P, Buttaci C, Stitik T, Yonclas P | title = Successful injection for coccyx pain. | journal = Am J Phys Med Rehabil | volume = 85 | issue = 9 | pages = 783–4 | year = 2006 | pmid = 16924191 | doi = 10.1097/01.phm.0000233174.86070.63}}
