Your body read this unfused segment as a lumbar and started to form a. 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. 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.
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. Type 2 with a small disc that does not. Partially lumbarized samples showed 1) gap (mean 1.43 mm) between s1 and s2 bodies; Partial lumbarisation can been seen with distinct disc space between the s1 and s2 or partial fusion between the bodies of s1 and s2 with no disc space between them.
2) incomplete separation between s1 and s2 neural arch elements with the s1 arches.
