Percutaneous Vertebroplasty: Is Bone Cement a Stress Riser?

A new cadaveric study published in Spine shows that vertebral augmentation with clinically relevant amounts of bone cement does not lead to stress peaks under the endplate.

Researchers examined 10 fresh-frozen vertebra loaded until failure and registered the force, displacement and pressure under the lower endplate. Then the vertebrae were augmented with clinical relevant amounts of bone cement, and then load again until failure.

 

The researchers found that stress peaks were not related to the location of the injected one and other failure load and stiffness were lower after augmentation, according to the report.
