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. Transitional (where there is only partial fusion of bony segments), or rudimentary (where there is complete fusion of the two adjacent vertebral. 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.

In addition there was evidence of.
But anatomical variations of the sacrum have been reported like sacralisation of fifth lumbar vertebra and.
Type 2 with a small disc that does not. Ferguson projection (ap lumbar spine radiograph, 30° cranial tilt) and lateral projection have been traditionally used as the best method for identification of lumbosacral. These have been classified into two types: Normally, the sacrum is formed by the fusion of five rudimentary vertebrae.
