2009, Clinical BiomechanicsCitation Excerpt :This was done to ensure an adequate sample number, as well as to control for diet, activity, genetics, illness and age. The anatomical and functional similarities between the human and porcine spine have been previously demonstrated (Yingling et al., 1999; Oxland et al., 1991) and additional work has determined that the trabeculae display similar architecture (Lin et al., 1997). A recent dissection study has shown that although differences between species do exist, the porcine cervical disc is a reasonable analog to the human lumbar disc for studies involving repetitive flexion/extension (Tampier, 2006).
Stress distribution in the intervertebral disc correlates with strength distribution in subdiscal trabecular bone in the porcine lumbar spine
2008, Clinical BiomechanicsCitation Excerpt :With regards the distribution of strength within the vertebral body, research has aimed towards better prediction of osteoporosis and related fractures. In these efforts, a number of researchers have shown an uneven distribution in mechanical and morphological properties of trabecular bone inside the vertebral body of human and quadrupedal species (Gong et al., 2006; Keller et al., 1989; Lin et al., 1997). Keller et al. (1989) found that the mechanical properties (strength, stiffness) and density of subdiscal trabecular bone specimens prepared from 12 regions within the vertebral body were highest in regions underlying the NP and lowest in regions underlying the AF.
