Mechanism of Formation of the Posterior Bony Spur of the Lumbar Spines in Young Adults

ABSTRACT

The bony spur formation without degenerative change in the lumbar spines in the young age group is quite interesting and is not uncommon. This bony spur is different from the degenerative spur in the old age group in shape and mechanism of formation. The authors analyzed 25 patients below 29 years old with such posterior lumbar bony spur. We concluded that posterioly located Schmorl's node is main cause of the bony pour in youn age group at lumbar region.
