Product Description

The Lumbar Spinal Stenosis Dynamic Disc Model is a powerful educational tool designed to enhance understanding of the dynamics of lumbar spinal stenosis and its impact on the spinal canal spaces for the nerves. 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 and the associated symptoms that accompany.

Overview of features:

  • crafted from real human specimen origin, identical scale and geometric bony shape
  • degenerated L4 and L5 vertebra (bone colored)
  • right severe facet arthrosis with moderate arthritis represented on the left evidence of subchondral sclerosis
  • decreased lumbar lordosis
  • thickened dynamic and elastic ligamentum flavum (yellow)
  • thinned and bulging one-part dynamic and elastic intervertebral disc (off-white)
  • optional cauda equina (white) with optional rootlets (blue)
  • projecting osteophyte from the superior articular process from the right L5 into the IVF demonstrating lateral stenosis
  • manual model extension will narrow the spinal canal and intervertebral foramina(IVF) by compressing and thickening the ligamentum flavum
  • manual model flexion will open the spinal canal and IVF spacing while reducing the disc bulge slightly and lengthening and stretching the ligamentum flavum

Description

This Dynamic Disc Model features two advanced degenerative lumbar vertebrae showcasing dynamic lumbar spinal stenosis—both centrally and laterally. The L4 and L5 vertebra are separated by a an elastic 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 (varying in thickness) 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 postures on the condition, promoting a comprehensive understanding of lumbar spinal stenosis and a path to management.

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. Whether you’re a medical professional seeking to enhance patient communication or an educator looking for an engaging teaching aid, this model is a valuable resource.

Optional features

Optional cauda equina and rootlets demonstrate increased friction in dynamic extension and opening spinal canal dynamics in flexion—an excellent educational tool to understand central, lateral and foraminal stenosis elements.

  1. Stephanie H

    I use this product in the VA hospital with my veterans. Side by side with a traditional spine mode I t is a phenomenal way to demonstrate how the facet joints and central canal change. It allows me to better educate my patients on their condition as well as what treatment we can use to help provide relief.

      Thank your Stephanie. Glad they are helpful.

  2. Debbie Wright

    I love this model – I use it daily alongside the LxH disc model to educate my patients on the spinal changes associated with degeneration and stenosis. I can’t recommend these models enough, they are an essential part of my practice.

  3. Francis W. Smith MD

    This is the best model lumbar spine I have seen. I am proud to possess one. It will be of great value when explaining to my patients as well as in my research using Upright MRI.
