The Lumbar Spinal Stenosis Dynamic Disc Model is a powerful educational tool designed to enhance understanding of lumbar spinal stenosis and its impact on the vertebral column. This meticulously crafted model provides a visual representation of the dynamic effects of extension and flexion on the spinal canal and intervertebral foramina, shedding light on this common degenerative condition. Description This Dynamic Disc Model features two lumbar vertebrae showcasing lumbar spinal stenosis. Both are in the central and lateral regions. The L4 vertebra demonstrates a one-part intervertebral disc with reduced disc height, while the L5 vertebra exhibits advanced arthritis and osteophyte projection into the intervertebral foramen (IVF). Additionally, the model showcases a thickened ligamentum flavum, along with optional nerves to include the rootlets. What sets this model apart is its ability to demonstrate how dynamic extension narrows the spinal canal and IVF, while flexion opens up these spaces. By simulating real-life movements, this model allows learners to grasp the impact of different spinal positions on the condition, promoting a comprehensive understanding of lumbar spinal stenosis. This Dynamic Disc model caters to a wide range of professionals and educators, including chiropractors, physiotherapists, spine surgeons, neurosurgeons, personal injury lawyers, teachers, and educators. It serves various purposes, such as anatomical teaching and biomechanics, patient education, student teaching, and spinal anatomy classes.
