Ganglion Impar Block Explained by a Colorado Pain Clinic

A Ganglion Impar Block is basically a nerve block that is placed at the ganglion impar region.The ganglion impar that is present in front of the coccyx and sacrum joint is a collection of nerve cells that are neutralized by the ganglion impar block. However, the shape of the ganglion impar and its location is different in every patient (Oh et al, 2004). Getting to this region, however, requires the use of a curved needle that can bypass the coccyx and sacrum joint. Sometimes a physician can also insert the block by inserting the needle through this joint as well.
