xray results confusing

[mydrs]

xray report reads "partial sacralization of L5 vertebral body on right". Please tell me what these means/indicates.

Thank you so much for the response. My 24 yr old son is experiencing alot of low back and bilateral leg pain that seems to be progressing. These were his xray results. At age 5-6 he had episodes where was unable to walk at all. He has c/o pain on and off over the yrs. The dr's continue to tell me "he is too young to have these pains". Is there anything I can do to help relieve his pain/help him?

Hello Dear,
Sacralization of a lumbar vertebrae is a common anatomical anomaly where usually the L5 vertebral body becomes incorporated into the S1 body. It is a benign process that does not need to be repaired
Some people, approximately 10% of adults, have a congenital anomaly in their lower back.
The  last transverse process a bony protrusion near the vertebra is partially attached to the sacrum, or “sacralized”. If this bony protrusion is attached to the sacrum, it can create a rudimentary joint (pseudoarticulation) where there shouldn’t be one. The resulting motion in this section of the spine can sometimes be a cause of localized low back pain and degenerative changes.
In your case there is incomplete or partial fusion.
