What are the consequences of lumbarisation of the s1?
Lumbarization (US) lumbarisation (UK) refers to a spinal bone
that takes on some of the appearances and physical characteristics
of another type of vertebrae or spinal bone. At S1 lumbarisation
means the S1 segment, which is usually, one of five fused segments
making up the sacrum or tail bone, is not fully fused or attached
to the rest of the tail bone. IT is a "sacral" segment that looks
like a "lumbar" segment. It appears to be 6th lumbar vertebrae. It
may have a disc or a rudimentary disc space. Functionally, a
lumbarized S1 usually does not have all the functions of a normal
lumbar vertebra. In most instances, this finding is interesting,
but does not usually cause pain or disability. In some rare cases
the joint may become irritated and painful due to injury.
