Usually the 5 Lumbar vertebrae (backbones between the chest/ribs and the hips) are separate, distinct bones, just like the 19 above them (12 thoracic or dorsal that typically each have ribs, and the 7 cervical in your neck).
Sometimes the bottom lumbar vertebra (#5) looks like it's trying to fuse with the sacrum. It's not completely separate, but it's not completely fused (usually) like the other bones in the sacrum (which form the triangular bottom of the spine and connect to the two hip bones through the sacroilliac joints).
Similarly, one can have "lumbarization of the first sacral segment" in which the first part of the sacrum looks like it's trying to unfuse from the rest of the sacrum!
The final note is this: either one of these situations might cause a tendency to get Back pain and YOUR pain probably led to the x-ray that revealed this condition in you. But nothing surgical needs to be done about either condition. The best advice is to (a) slowly strengthen your back, and (b) strengthen your back slowly! (smile) Ask your doctor/physical therapist/chiropractor/etc.
Sacralization means that the last vertebra in the lumbar series is part of the sacrum instead. It is a normal human variant. However, the last lumbar vertebra is L5. Sacralization of L3 is likely to be a typo.
Sacrality is the property of being sacral - or sacredness.
Sacralization is the fusion of the last lumbar vertebrae with the first segment of the sacrum.
Sacralization is the process of imbuing something with religious or sacred qualities. It involves elevating an object, place, or person to a higher status, often through rituals, ceremonies, or symbolic actions to invoke spiritual significance.
