Vascular Clear CxH cervical disc model

Crafted with the same materials, and based on equally detailed and up-to-date research as ddd’s lumbar models, these two new cervical models are copies based on real human bone structure, and contain a two-part intervertebral disc that can be manipulated for demonstration through six degrees of freedom.  The models are designed to demonstrate annular disruption, nuclear migration with manual compression, including posterior nuclear migration with various compressive loads, and shows the fibrous nucleus pulposus.

Biomechanical LxH and Surgical Simulator LxH

Biomechanical LxH lumbar disc model

Both of ddd’s new lumbar models offer a realistic two-part disc with six degrees of freedom and an L4 endplate lens.

As the name suggests, the Biomechanical LxH can be used for biomechanical testing. The model demonstrates higher tensile and tear strength annular properties, a white fibrous nucleus pulposus and is able to withstand forces known to cause endplate failure.

The Surgical Simulator LxH model demonstrates a full radial tear, white fibrous nucleus pulposus and simulated granulation with extruded material.   This model has been tested by a neurosurgeon to ensure anatomical, spatial and tensile accuracy.

About ddd spine models

The degree of detail afforded by ddd’s spinal model is being recognized by a growing number of spine professionals, both medical and chiropractic, as indispensible for educating patients and students, alike.   

“Many months of R&D with real fresh specimens have been closely investigated to produce spinal disc models that more closely resemble the natural tissue,” says Dr. Fryer, president and founder of ddd. Fryer is a practicing chiropractor in Nanaimo BC whose own spinal research has been published in medical journals, and includes his latest paper which was accepted into The Spine Journal in January of 2010.   

“For doctors,” adds Fryer, “ddd models save time by improving communication and confidence as patients see, touch and understand common spinal disc issues that lead to low back pain and other related spinal conditions. For educators, these models are simply much closer to the real thing, allowing curious minds to understand more clearly the dynamic nature of intervertebral motion.” 

The new cervical and lumbar models from ddd can be ordered online, along with all current lumbar models, through the company’s website at www.dynamicdiscdesigns.com .
