One document details the use of fluoroscopic scanning - using X-rays to show images of the inside of an object.

Describing the bone meeting the socket, Kelly said "we're basically taking an egg-shaped femoral head and through the use of a camera, a motorized burr and Fluoroscopic imaging, we're reshaping the bone to a predetermined shape."

“I would want it to be performed, if it were my injection, under fluoroscopic guidance,” said Dr. Ray M. Baker, president of the International Spine Intervention Society.

St. Jude spokeswoman Amy Jo Meyer said the company has expanded its regular warranty to include a baseline fluoroscopic or X-ray screening if a patient's insurer does not cover it.

In addition, according to the Journal, FDA is now asking St. Jude to include routine fluoroscopic evaluation of Durata in its post-market study.
