- What was not known at the time was that the number of sacral vertebrae is related to age: as the animal got older two additional vertebrae fused to the original three sacral vertebrae.
- The lumbosacral joint, between the last lumbar vertebra and the fused sacral vertebrae is atypical in that it allows considerably more motion, about 30 degrees of flexion and extension.
- The superior surface of the first sacral vertebrae is called the promontoryand articulates with the fifth lumbar vertebrae.
- The number of lumbal vertebrae is reduced, the number of sacral vertebrae is enlarged, and an external tail is absent (Table 1.
- The presence of cystic structures in the cavity of the small pelvis in conjunction with a congenital defect in the bodies of the sacral vertebrae is an indication for conducting pneumomyelography so as to make a more precise diagnosis.
