Surgery has not been an option in the past for children with ACL tears because of the possible damage to the growth plate that can cause serious problems later in life.
With this new technology, surgeons can actually see from one point to the other on either side of the knee, and can safely position the tunnels where they will place the new ligament.
John Xerogeanes, MD, chief of the Emory Sports Medicine Center, and colleagues in the laboratory of Allen R. Tannenbaum, PhD, professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University, have developed 3-D MRI technology that allows surgeons to pre-operatively plan and perform anatomic anterior cruciate ligament (ACL) surgery.
British scientists have developed a breath analyzer that tells how much fat you are burning off at the gym. The device is being built to pinpoint the moment when a sweaty session on the treadmill finally starts to pay off by detecting when the body has used up its supply of food energy and switches to breaking down fat instead.
Exercise machines currently estimate when people have entered the “fat burning zone”.The breath analyzer works by picking up minute changes in the levels of a molecule called acetone in people’s breath, which is given off when the body starts to burn fat. Gus Hancock, whose company Oxford Medical Diagnostics has developed the machine, said, “Acetone is a molecule that is produced by people who are burning fat rather than food.”
