Abstract
Lumbar disc herniation in teenagers may show a tear at the ring apophysis which may show spurformation. This ring apophysis tear may occur not only in teenagers but also in cases of adults showing lumbar disc herniation. Accordingly, Vertebral spur generated after lumbar disc herniation in teenagers and adults and posterior vertebral spur in lumbar spinal stenosis were compared by the type of spur in order to investigate the etiology or cause of posterior vertebral spur in each case.
1) Bony spur generated after lumbar disc herniation in teenagers and adults and vertebral spur generated at posterior site of the lumbar vertebra in cases of lumbar spinal stenosis cannot be discriminated morphologically.
2) The etiology of posterior vertebral spur in adult cases was considered to be associated greatly with lumbar disc herniation.
