Product Description

The Medial Branch Dynamic Disc Model is a cutting-edge anatomical model designed to enhance understanding and education in the field of spinal anatomy. This one-level dynamic lumbar model (L4-5) features realistic characteristics, including facet innervation and herniation, making it an invaluable tool for healthcare professionals and educators.

The Medial Branch Dynamic Disc Model uses our Professional LxH Model to showcase the L4 and L5 lumbar vertebrae, along with a two-part intervertebral disc consisting of the annulus fibrosus and nucleus pulposus. This model also includes essential components such as the cauda equina, rootlets, nerve roots, dorsal root ganglion, and uniquely, the medial branches to an inflamed facet capsule.

 

he Professional LxH Dynamic Disc Model is a remarkable human bony replica designed to showcase the intricate dynamics of a functional motion segment of the spine. This lumbar disc model recreates the L4 and L5 lumbar vertebrae, complete with the soft tissue components of the intervertebral disc. It also includes the annulus fibrosis and nucleus pulposus. With its realistic characteristics, this model sets itself apart by providing a dynamic representation, specifically highlighting herniation.

Overview of features:

  • crafted from real human specimen origin, identical scale and geometric bony shape
  • flexible and dynamic herniating nucleus pulposus (extrusion under load and retracts when the compression is released)
  • circumferential (diffuse) disc bulge
  • superimposed disc protrusion
  • cauda equina (basic nerves) with optional rootlets (blue)
  • limacon shaped annulus
  • peripherally exposed calcified endplate
  • elastomeric white articular cartilage
  • subchondrial bone exposed with a hyaline fibrillation
  • bone coloured L5
  • white superior endplate matching the colour of the articular cartilage
  • blue coloured intervertebral disc innervation
  • right posterior-lateral radial and circumferential(concentric) fissure
  • intervertebral disc innervation to the outer third of the annulus
  • nerve ingrowth (neo-innervation) to the inner two-thirds of the damaged annulus to help demonstrate chronic pain
  • left partial posterior-lateral radial tear matching up to the disc protrusion (contained nucleus)
  • anterior circumferential tear
  • transparent L4
  • randomly scattered and embedded black nuclear structures to show nuclear-shifting dynamics through the L4 view lens easily
  • L5 superior endplate pores (black)
  • L5 superior endplate lesion (red)
  • vasculature in L4 vertebral body (red)
  • facet subchondrial vascularization (red)
  • facet tropism (L5 inferior)
  • red inflamed flexible left L4-5 articular capsule
  • medial branches extending form the posterior division of the L4 and L5 nerve root

What sets this model apart is its dynamic nature, allowing for a realistic representation of herniation and the medial branches connecting to the facet joint from two levels. Studying this model gives professionals valuable insights into spinal biomechanics and anatomical structures and the interplay between the disc and facet dynamics.

This Dynamic Disc model caters to a wide range of users, including pain interventionalists, chiropractors, physiotherapists, spine surgeons, neurosurgeons, personal injury lawyers, teachers, and educators. It serves as a valuable resource for anatomical teaching, biomechanics research, patient education, student instruction, and spinal anatomy classes. 

Whether you are a seasoned professional looking to deepen your knowledge or an educator seeking an engaging teaching tool, this model is an indispensable addition to your practice or classroom.
