Lumbar Vertebra Set (Arthritic & Normal)

Five normal and five arthritic lumbar vertebrae. One set is normal and is typical of a young adult who has experienced no unusual back trauma. The edges of the vertebral bodies are smooth and regular in shape. One set is osteoarthritic, which is typical of an older adult or a person with a history of heavy labor (or both). The edges of the vertebral bodies are sharp and irregular. Bony outgrowths (osteophytes) are present.
