This model of Multilevel Dynamic Cervical Spinal Stenosis illustrates a centrally protruding nucleus pulposus at the C6-7 level, achieved with a two-part intervertebral disc. It demonstrates spinal canal narrowing due to herniation under compression load and during dynamic extension. The ligamentum flavum has been thickened to simulate natural degenerative changes, while the cervical lordotic curve is reduced to highlight disturbed facet parallelism. This C5-7 model, featuring the C6-7 CxD segment, includes the C5 vertebra and an elastic, one-part C5-6 disc.
