BIRMINGHAM, Alabama -- It was if the surgeon had another set of hands to help during surgery to replace a shoulder. Floating ethereally over the surgeon's own hands, the hands guided and pointed as the surgeon worked the scalpel. They were virtual hands from a doctor more than 100 miles away in Atlanta. Using Google Glass, a wearable computer with head-mounted display, and using virtual technology developed by the University of Alabama at Birmingham, orthopedic surgeon Dr. Brent Ponce performed a shoulder replacement surgery Sept. 12 at UAB Highlands Hospital, UAB announced today. From Atlanta, Dr. Phani Dantuluri watched, talked and virtually placed his hands into the surgical field.(via http://blog.al.com/spotnews/2013/10/uab_surgeon_performs_surgery_u.html)
