...These results are consistent with previous findings by Marchand and Ahmed (1990), who measured the lamellar fiber angles at the ventral and dorsal midsagittal position for the lumbar levels L2–L3 and L4–L5....

...In contrast to the latter result, previous studies (Cassidy et al. 1989; Hsu and Setton 1999; Marchand and Ahmed 1990) report that the lamellar thickness is larger at the internal regions than at the external regions of the anulus fibrosus....

...…fiber angle increases from 28 at the edge of the disc to 45 beside the nucleus pulposus referred to as the transverse plane of the spine, while the intra-lamellar variation of the fiber angle ranges from about 20 at the ventral position to about 70 at the dorsal position (Marchand and Ahmed 1990)....

...…because it is known that aging is associated with significant chemical changes of the anulus fibrosus, such as a reduction of the water content (Hickey et al. 1986; Isherwood et al. 1986; Jenkins et al. 1985; Urban and McMullin 1988) and the amount of proteoglycans (Urban and McMullin 1988)....
