Lumbopelvic Dynamic Spine Model

This unique model is a meticulously crafted and flexible tool that offers a comprehensive understanding of the lumbar spine and ilium in the hands of a professional. This dynamic lumbopelvic model is designed to improve anatomical teaching, biomechanical analysis, and patient education of low back and pelvic pain.

Overview of features:

  • crafted from real human specimen origin, identical scale and geometric bony shape
  • white solid opaque L3, L4, L4, sacrum.
  • bone coloured ilia.
  • dynamic and elastic intervertebral discs at L3-L4, L4-5, and L5-1.
  • one-part disc at L3-4
  • two-part discs at L4-5 and L5-1 including the nucleus pulposus and annulus fibrosus
  • flexible and dynamic herniating nucleus pulposus (extrusion under load and retracts when the compression is released) a the L4-5 level
  • circumferential (diffuse) disc bulge at L4-5
  • superimposed disc protrusion at L4-5
  • dynamic and elastomeric simulated articular cartilage at sacroiliac joints and pubic symphysis
  • early degenerative changes at the SI joints with an osteophyte projection from left ilium
  • red colour to represent subchondrial vascularisation at all facet levels and pelvic ring joints
  • facet tropism (L5 inferior)
  • optional cauda equina with or without rootlets, simulated elastomeric acetabular hyaline cartilage
  • stand included

Expect 4-5 week lead time.

NOTE: Model has now (as of 2021) semi translucent annulus fibrosus as see in images. Colours may vary slightly from images and video.


This Lumbopelvic Dynamic Spine Model is a custom-crafted representation of the lumbar spine and ilium, meticulously designed to provide an accurate and realistic demonstration of their intricate interplay. 

This model consists of three lumbar vertebrae (L3, L4, L5), the sacrum, and the pelvis, complete with intervertebral discs, viscoelastic sacroiliac joints, and a simulated elastomeric pubic symphysis.

With a herniating nucleus pulposus and disc protrusion at the L4-5 level, this model accurately depicts common spinal pathologies. The elastomeric sacroiliac joints, adhered to a matching ilium and sacral bony specimen, allow for a fully flexible pelvic ring, enabling the demonstration of six degrees of freedom. This lifelike representation showcases the intimate relationship between the lumbar spine and pelvis.

The standout feature of the Lumbopelvic Dynamic Spine Model is its fully flexible pelvic ring, providing an unparalleled level of realism and functionality. This allows for a dynamic exploration of the interaction between the lumbar spine and pelvis, enhancing the learning experience and facilitating a deeper understanding of biomechanics and pathology.
