Stages Of Disc Prolapse & Vertebral Degeneration

Stages of Disc Prolapse & Vertebral Degeneration

The 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 finest bone structures are accurately depicted.

• 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.
• The model can be disassembled into vertebrae and intervertebral discs.
• Supplied on base.
