Thomas Zdeblick, an orthopedic surgeon at the University of Wisconsin-Madison, raised eyebrows three years ago when it was learned that he had been receiving $400,000 yearly from the medical device company Medtronic.
But a document obtained Friday indicates the actual yearly payments averaged about 10 times that figure.
Zdeblick, a professor and chairman of the department of orthopedics at UW, received more than $19â??million in payments from Medtronic from 2003 through 2007, according to a letter that Sen. Charles Grassley R-Iowa sent Monday to UW System President Kevin Reilly.
