Tailbone Pain and Sacroiliitis

      Sitting on the bottom of your spinal column at the back of the pelvis is your sacrum and coccyx. The sacrum is commonly called the “tail bone” or “base bone” and is wedge-shaped. It is an extension of the spinal column and articulates with the two pelvic bones on either side, forming the sacro-iliac joints. Five individual bones make up the sacrum and by the age of 30 they fuse into one solid bone. The sacrum helps stabilize the pelvis and houses an extension of the spinal cord and a group of nerves called the sacral plexus. These nerves exit through the foramen or small openings on each side of these 5 segments. Tissues and organs in the pelvic region as well as muscles of the buttocks, hip and portions of the leg and thigh are innervated by these nerves. Subluxations of the sacrum and or pelvis can result in such conditions as hemorrhoids, scoliosis, degenerative discs or hips, and pain when sitting or lying on one side.
      The base of the sacrum is broad and contains a rounded flat area where the 5th lumbar vertebra and its disc sit. There are joints on either side that stabilize and allow movement at their junction. The tilt of the sacrum at this junction in relation to the 5th lumbar and its disc and joints can be a source of pain also. Too much forward tilt of the sacrum can cause increased wedging of the disc space and jamming of the facets or joints. Disc bulging with radicular or sciatic pain to the leg can occur. The facet pain usually radiates across the lower back with a burning and is not as specific as sciatica. Sitting for even short periods of time can aggravate the area until one can stretch and move or change position. The sacro-iliac joints can also be a source of severe pain related to sacral or pelvic subluxation. This pain is usually over the buttock region on either side and is painful to lie down on.
      A flattened pelvic or sacral tilt affects the more anterior elements of the vertebrae . The weight of the body is translated more over the discs and the lumbar lordosis or frontal curve is oftentimes flat or reversed. Posterior connective tissue ligaments become stretched and weakened. The discs can degenerate and result in foraminal stenosis or narrowing of the nerve openings impinging on vital nerve supply to the lower body.                                          
      While pelvic pain can be related to other pathology, simple tests can be formed to determine if the source is bio-mechanical or organic. By correcting the subluxation of the sacrum or pelvis, pain relief can be instantaneous. Balance is restored removing stress on the discs and joints allowing healing to take place.
