Cervical Spinal Stenosis Model
A multilevel dynamic cervical spinal stenosis model demonstrating a centrally protruding nucleus pulposus at C6-7 achieved with a 2-part intervertebral disc to show spinal canal narrowing both with herniation under compression load and dynamic extension. Ligamentum Flavum has been thickened to represent natural degenerative changes. Cervical lordotic curve has been reduced to show disturbed facet parallelism. This C5-7 model is our C6-7 CxD Model with C5 vertebra and an elastic 1-part C5-6 disc.
