Stages of Disc Prolapse and Vertebral Degeneration Model

The Stages of Disc Prolapse and Vertebral Degeneration Model illustrates degenerative changes to the vertebral bodies and intervertebral discs of the lumbar spine, in various degrees. Based on the original cast of a human lumbar spine, even the finest bone structures are accurately depicted in this precise, useful model.  It can be disassembled into vertebrae and intervertebral discs, allowing for a more detailed study of the structure of the lumbar spine.

Supplied on base for easy display, this model makes a great aid to medical education and anatomy studies. It can be used in demonstrations with students, or as a tool to educate patients about potential injury.

Conditions of the Vertebral Degeneration Model

The following conditions are shown, from top to bottom, on this model of the human lumbar spine:

• Intervertebral disc in healthy condition
• Lumbar vertebra (L1) without degenerative changes
• Intervertebral disc with protrusion
• Lumbar vertebra (L2) with beginning degenerative changes
• Intervertebral disc with medial prolapse
• Lumbar vertebra (L3) with advanced degenerative changes
• Intervertebral disc with intraforaminal prolapse on the right
• Lumbar vertebra (L4) with strong degenerative changes and bony constriction of the left intervertebral foramen
• Extremely narrowed intervertebral disc
• Lumbar vertebra (L5) with strong degenerative changes and bony constriction of the left intervertebral foramen with pressure on the spinal nerve root L5 on the left

Applications of the Stages of Vertebral Degeneration Model

This model is a great tool for student and patient education, therefore particularly suited for use in the following environments:

• Schools
• Universities
• Hospitals
• Doctor’s offices
• Rehabilitation centres
• Laboratories
