Prompted by some mainstream media finger pointing, UBM Canon's editor-at-large Brian Buntz takes a look at some of the numbers behind the controversy surrounding the Synthes Norian XR product. Buntz reports:

• 94.17% of adverse reports involving calcium compound bone void fillers were filed by manufacturers compared Vs. 97% across the broader category of bone cements and fillers.
• In 2011, Synthes reported the most adverse events of all the makers of calcium compound bone void fillers, an increase from 0 in 2008 to 22 in 2011.
