Biomechanics


Core of the vertebra consists of connecting rods and plates of bone that form a three dimensional trabecular system.

Inhomogeneous pattern of loss of trabecular pattern in osteoporosis.

The horizontal trabeculae that connect the neighboring vertical trabeculae are lost earlier in the course of osteoporosis than are the vertical trabeculae.


Euler’s Column Theory

Compressive strength of a column

Area= r2



Thus combined loss has a profound loss on the compressive strength loss of the vertebral body.
