CONGENITAL ANOMALIES OF THE VERTEBRAL COLUMN Flashcards
Two or more vertebrae may be united forming one bone with no joint between. It is also called the “bamboo spine”.
Fusion of Vertebrae
Maybe the (R) or (L) half of a vertebra maybe absent, or maybe one half of one vertebra may fuse with the vertebra above or below, leaving the other half as a separate bone.
Hemi vertebrae or Butterfly Vertebrae
Is the lack of union or malunion of laminae. In [. ], the laminae of a vertebra may fail to unite each other in the midline posteriorly.
Occurs usually between L5-S1
Spina Bifida
A defect maybe present between the superior and inferior articular processes of a vertebra. This defect usually occurs at L5.
Inter-articular Defect
The lower part of the Sacrum may fail to develop, if so, the coccyx will also be absent.
Absence of Sacrum
The last lumbar vertebra may be partly or completely fused with the first sacral segment.
