The cord terminates normally at l1/2. 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. Your body read this unfused segment as a lumbar and started to form a.

Transitional (where there is only partial fusion of bony segments), or rudimentary (where there is complete fusion of the two adjacent vertebral.
Transitional anatomy, with rudimentary disc at s1/s2.
These have been classified into two types: 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. Type 2 with a small disc that does not. A large circumscribed midline mass destroys the sacrum from the level of the inferior aspect of.
2) incomplete separation between s1 and s2 neural arch elements with the s1 arches. Ferguson projection (ap lumbar spine radiograph, 30° cranial tilt) and lateral projection have been traditionally used as the best method for identification of lumbosacral. Partially lumbarized samples showed 1) gap (mean 1.43 mm) between s1 and s2 bodies; In addition there was evidence of.

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.
