Sacralization: What You Need To Know?
In human spine , there are five lumbar vertebrae locate above the pelvis . Below this , there are five sacral vertebrae , which are fuse , proceeding to the tailbone . The spinal column is form during the normal embryotic development and each type of vertebra assumes its character and position .
The lumbar region of the spinal column mainly facilitates movement of the back and supports the body exercising weight . The five lumbar vertebrae are designed in a style that can help its social function and are count from above downwards as L1 to L5 . The 5th lumbar vertebra has a peculiar contour and equipment characteristic to fit its normal location and function .
In some cases , during the embryonic development , some alteration can cause congenital anomalies , leading to misshapenness of the vertebral bodies . Such inborn blemish in coalition or formation of certain part can affect individuals in different ways . Sacralization is a innate condition in which the lumbar vertebra fuses completely or partially with the sacrum on either or both sides .
What Is Sacralization of L5 or Sacralization of Fifth Lumbar Vertebra?
Sacralization of L5 or sacralisation of fifth lumbar vertebra is a congenital anomalousness , in which the lumbar vertebra , principally its transverse mental process , gets flux or semi - coalesced with the sacrum or the Ilion or to both . This unification can go on in one or both side of the consistence . Sacralization leave to optical fusion of the L5 ( fifth lumbar vertebra ) and S1 ( first sacral vertebra ) and the inter - vertebral disc between them may be narrow .
Due to sacralization , the L5 vertebra appears and works more like the sacral constituent and hence it is termed as sacralized vertebra . As the fifth lumbar vertebra fuses with sacrum , it is considered as a part of sacrum leaving only four lumbar vertebrae . Hence , the condition is also called as ‘ one less vertebra ’ .
Sometimes it is observed that the lumbar vertebral bodies are not fused , but only the transverse process may be fused with the sacrum ; whole on one side and incompletely on the other side . When fusion or sacralization pass with sacrum , it is primal sacralization and when fusion occur with the sides of sacrum , it is transversal sacralization ( unilateral for one side and isobilateral for both sides ) .
Symptoms Of Sacralization And Its Impact On Health
Sacralization of lumbar vertebra may be asymptomatic but is not always clinically unimportant . The sacralized lumbar vertebra , which is normally a non - consolidated vertebra , may sometimes face up challenge in its function after getting fused with the sacrum . As the radiation diagram of sacralization varies from mortal to individual , the associated problems , if any , may also vary in severity and intensity .
While sacralization may not affect at all , it can cause problems in some cases . Sacralization may be at time associate with problems in biomechanics and affect the path of drift and military strength ascendance . In sacralization , the L5 vertebra may not be entirely fused along the integral elbow room . Being immix on one side and semi - fused or non - amalgamated on the other side can make the workings of the backbone unmanageable . The spinal components above the L5 have to solve hard to contend with this , which may cause strain on them .
Some persons with sacralization may confront with complaints ofback pain , spinal orradicular painand related to signs . Sometimes due to the abnormal fusing of the lumbar vertebra with the sacrum , the lumbar movements can get affected and conditions like lumbar scoliosis can develop . In some cases , lumbar epidural effects can also be fancy . As the inter - vertebral phonograph record between L5 and S1 is minute or fragile , there are higher opportunity ofdisc herniation . trouble like disc extrusion or prolapse especially between the 4th and 5th disk , decadency of disc , etc . Sacralization may also be an authoritative condition in magnetic disc surgeries .
Sacralization can sham the centre of gravitational attraction at the spinal cornerstone . As the 5th lumbar vertebra gets fused with the sacrum and gets sacralized , the fourth lumbar vertebra becomes the last lumbar vertebra . Hence , the L4 vertebra bear the province of being the prat of spinal movement . However , the L4 vertebra may lack the ability to perform this social occasion like L5 and can cause problems . With a fused L5 , it is hard for L4 to make out with the increased demand , cause over - consumption and undue straining to the record between L4 and L5 . This can step by step go to pain and irritation in the part of low back .
What Is The Treatment For Sacralization?
Sacralized lumbar vertebra can affect spinal movement and put excess stress on the lumbar vertebrae and in - between disk . right diagnosis can be done by using imaging studies . intervention depends on the nature of the anomaly and associated symptoms .
Treatment for Sacralization may include :
As there are many causes of back infliction , further studies are required to determine the data link between sacralization and back pain .
