L5 and S1 vertebrae Save The L5-S1 segment spans two different portions of the spine, the lumbar and the sacral. The L5 and S1 vertebrae have different features: L5consists of a vertebral body in front and an arch in the back that has 3 bony protrusions: a prominent spinous process in...
L5-S1 spinal unitfinite element methodGasser-Ogden-HolzapfelOgdenT2-mapped MRIThe L5-S1 segment of the spine is highly susceptible to injury, frequently causing low back pain. The segment has gained a lot of scientific interest, leading to many experimental works that can be found describing ...

1) L5/S1 L5~S1 1. Objective To determine the variability of the anterior vascular anatomy at the lower lumbar spine and provide anatomic data for the design ofL5/S1anterior fusing plate. 目的对脊柱L4~S1段腹侧局部血管解剖进行研究,为L5~S1前路内固定系统的设计提供解剖学依据。
rather than due to degenerative factors. The CSA of the PM at the L4–L5 and L5–S1 levels is correlated with curvature of the spine, because the lordosis apex is generally at the L4 vertebrae level, so when lumbar lordosis (LL) increases, the angle of the disc at the L4–L5 level ...
