Short summary
In elderly patients (>60 years), lumbar disc herniation is primarily caused by avulsion of the cartilaginous end-plate with the anulus fibrosus, not nucleus pulposus herniation.

Key points
- Lumbar disc herniations in 29 elderly patients (>60 years) were studied pathohistologically.
- In 70% of patients aged 60-69 and 80% of patients over 70, herniated fragments comprised the anulus fibrosus and cartilaginous end-plate.
- The authors conclude that the cartilaginous end-plate avulsed from the vertebral body and herniated with the anulus fibrosus.
- This end-plate avulsion type of herniation occurs more frequently than nucleus pulposus herniation in patients over 30 and is likely most common in the elderly due to disc degeneration.

Abstract
Twenty-nine fragments from herniated lumbar discs of patients over 60 years of age were studied pathohistologically. For comparison, 109 discs from patients under 59 years of age also were observed. They were classified into seven types according to their composition. In 70% of discs from patients between 60 and 69 and in 80% of discs from patients over 70, the fragments were composed of the anulus fibrosus and the cartilaginous end-plate. The authors concluded that the cartilaginous end-plate had avulsed from the vertebral body and herniated with the anulus fibrosus in these cases. This type of herniation occurs more often than herniation of the nucleus pulposus over 30, and may be most common in elderly patients because of their advanced disc degeneration.
