Vertebroplasty in Goat Model Using Macroporous Calcium Phosphate Cement (MCPC®)
We performed vertebroplasty on goat model by injecting a new macroporous calcium phosphate cement MCPC®. The mechanical property of the cement is about 12MPa after 24 hours (compression test). The cement matrix is totally transformed into poorly crystallized apatite in 48 hours. This study demonstrates that MCPC cement was suitable and efficient for a spine application. Its injectability allows to be used in mini invasive surgery and its mechanical properties are compatible to support spine strength. In addition, a bone ingrowth onto the BCP granules occurred with time.
