Excerpt presented by Phila Chiropractic
The Sacrum is the largest vertebra; is curved with its
convexity backward; is commonly made up of five fused
segments ; has only rudimentary spinous and transverse
processes except the first ; and shows sixteen openings, eight
anterior and eight posterior, or four on either side of the
median line in front and the same number and arrangement
behind. These openings permit the exit of the anterior and
posterior primary divisions of the sacral nerves separately.
The Coccyx, usually composed of four fused segments,
is a triangular bone which articulates with the Sacrum
above and is free at its distal extremity. Its portion of the
neural canal is open posteriorly and contains merely the
thread-like termination of the cord membranes. It is fre-
quently ankylosed to the Sacrum, sometimes in an abnormal
position so as to impinge the single pair of coccygeal nerves.
