Rudimentary S1-s2 Disc Figure 2 From The Association Between Lumbar Rib And Lumbosacral
But anatomical variations of the sacrum have been reported like sacralisation of fifth lumbar vertebra and. Transitional (where there is only partial fusion of bony segments), or rudimentary (where there is complete fusion of the two adjacent vertebral. Your body read this unfused segment as a lumbar and started to form a.

Resnick and niyagama (24) demonstrated that the condition which was previously identified by schmorl and junghanns (25) indicates two distinct conditions of intervertebral disc. Lumbosacral transitional vertebrae (lstv) are increasingly recognized as a common anatomical variant associated with altered patterns of degenerative spine changes. Sagittal ct image demonstrates “squaring” of a lumbarized s1 vertebral body (black arrow).
A “type ii” disc is a rudimentary disc which is smaller than the transitional one, maintains its signal intensity, has no intranuclear cleft, and is associated with fusion of the anterior endplates, both.
In addition there was evidence of. Similarly, it has been observed that when a lumbarized s1 is present, the disk space between s1 and s2 is larger than the rudimentary disk that is most often seen in spines. This l5 vertebra is sacralized in that it is more anatomically associated with the sacral level with a rudimentary disc between it and the segment below. These have been classified into two types:
Normally, the sacrum is formed by the fusion of five rudimentary vertebrae. Depending on the number of thoracic vertebrae, lumbar vertebrae, and sacral segments, they can be thought of as a lumbarised s1 segment or sacralised l5 segment. Plain radiographic studies have shown that the lumbosacral intervertebral disc is of significantly reduced height compared with normal lumbosacral interval discs,6and that on lateral.
