27 de abr. de 2022 · The estimated intradiscal pressures (0.2-0.56 MPa) at 0 N axial load were comparable to in vivo measurements found in the literature, whereas at 40 N, the values were 0.39-0.93 MPa. With increased segmental mass (5th to 95th), the disc loads, translations, and muscle forces/activities increased to 69% at 0 N and 34% at 40 N axial load.
27 de mar. de 2015 · Chapter 24. Intradiscal Pressure. The intervertebral disc is composed of a central gel-like nucleus pulposus (NP) and surrounding anulus fibrosus (AF) with a unique lamellar structure. Each layer of the AF is composed of mainly type I collagen, 1 in which the collagen fibers are organized in an oblique direction that alters at sequential layers.

1 de ene. de 2002 · Ten human cadaveric lumbar spines were loaded in the three main anatomic planes with pure moments of 3.75, 7.5, and 7.5 Nm plus a follower load of 280 N. Intradiscal pressure and intersegmental ...
5 de may. de 2017 · 3.2. The Effects of Human Weight on the Intradiscal Pressure. Figure 5 shows the comparison of the IDP of nucleus pulpo-sus for each IVD vertebral segments in the lumbar spine. It was found that the IDP was increased as the human spine physiological loading increased in flexion motion where the highest pressure was 1.26MPa at L1-L2 vertebral ...
15 de dic. de 2001 · for studying the mechanical behavior of the lumbar spine. The influence of a follower load on intradiscal pressure at the different levels is unknown. Methods. Ten human cadaveric lumbar spines were loaded in the three main anatomic planes with pure moments of 3.75, 7.5, and 7.5 Nm plus a follower load of 280 N. Intradiscal pressure and intersegmental rotation were measured at all levels ...
