The ligaments connecting the last lumbar vertebra with the sacrum are similar to those which connect the segments of the spine with each other.
1. The continuation downwards of the anterior and posterior common ligaments. 2. The inter-vertebral substance connecting the flattened oval surfaces of the two bones, thus forming an amphiarthrodial joint. 3. Ligamenta subflava, connecting the arch of the last lumbar vertebra with the posterior border of the sacral canal. 4. Capsular ligaments and synovial membranes connecting the articulating processes and forming a double arthrodia. 5. Inter- and supra-spinous ligaments. The two proper ligaments connecting the pelvis with the spine are the lumbo-sacral amd lumbo-iliac. 
The Lumbo-sacral Ligament (fig. no) is a short, thick, triangular fasciculus, connected above to the lower and front part of the transverse process of the last lumbar vertebra, and passing obliquely outwards, is attached below to the lateral surface of the base of the sacrum; becoming blended with the anterior sacro-iliac ligament. This ligament is in relation anteriorly with the Psoas muscle. The Lumbo-iliac Ligament (fig. 110) passes horizonally outwards from the apex of the transverse process of the last lumbar vertebra, to that portion of the crest of the ilium immediately in front of the sacro-iliac articulation. It is of a triangular form, thick and narrow internally, broad and thinner externally; and is in relation, in front, with the Psoas muscle; behind, with the muscles occupying the vertebral groove; above, with the Quadratus lumborum. |
