Limbus vertebra vs intercalary bone - illustration

Case contributed by Dr Matt Skalski


Limbus vertebra vs intercalary bone: illustration

The respective appearance of intercalary bones and limbus vertebrae are illustrated. Limbus bones/vertebrae comprise part of the normal contour of the VB with herniated disc material undercutting the segmented piece of bone, whereas intercalary bones are entirely disc based, apart from the adjacent vertebral bodies. 

Case Discussion

Degenerative spinal disease is extremely common and comes in a variety of forms. Limbus vertebrae and intercalary bones are common associated findings, but distinctly different in their appearance and pathogenesis.
