Significant changes to the ligamen- region of the disc was observed discount 5mg kemadrin amex, and a corresponding 30% tous structures of the spine with aging have been reported. The For example, the elastic modulus of the main substance of width of the functional annulus increased by 80% and the the anterior longitudinal ligament increases twofold, while height of the compressive stress peak in the annulus by the modulus of the ligament insertion decreases threefold, 160% with degeneration. While age and degeneration were between 20 and 80 years of age, and the strength of the closely related, the state of degeneration had the most pro- bone ligament junction decreases twofold with aging found influence on the measured stress distributions.

The natural swelling pres- The correlation between degenerative changes to the ver- tebra and the disc remains an open question. Endplate fracture or vertebral body deformity is not necessarily as- sociated with disc degeneration. While disc thinning may be implied from observed stature changes, disc morphom- etry is altered to accommodate changes to the vertebral body shape by extrusion into the concave endplate, but in- dicators of degeneration (i. Based on MRI imaging and DEXA measurements, a negative correlation between vertebral BMD and interver- tebral disc degeneration has been shown. Dai has suggested that, for patients with severe osteoporosis, ver- tebral bodies adjacent to discs with decreased height or signs of degeneration are less likely to be deformed. In an in vitro study of the influence of disc degeneration on the mechanism of vertebral burst fractures, Shirado et al. In spec- imens with severe disc degeneration and osteoporosis, no burst fractures were observed. Further analysis of their test results led to the conclusion that stresses were concen- Fig.
