A new study found that people with “sway back” have an increased risk of developing lower back pain from disc bulges.
Conclusions: “The increased level of forward shear generated in moderately sloping lumbar segments when compressed was abnormally damaging to the lateral regions of the disc annulus. This is consistent with the view that shear differentially loads the oblique-counter oblique fibre sets in the lateral annulus, increasing its vulnerability to early disruption and overt herniation”
