Bones in motion: Brown scientists to create new 3-D X-ray system
...geon trying to figure out the best way to repair a torn
knee ligament or an evolutionary biologist tracing the disappearance of digits in pigs would face a difficult task. To see the exact position and movement of bones and the ligaments, tendons and cartilage that surround them, would require cutting int...

... 5 percent and 40 percent of people who may have a torn
rotator cuff have no accompanying shoulder pain. What surgeons do know is that rotator cuff repairs can fail in the days and weeks after surgery. Some studies have reported short- to intermediate-term recurrence rates from 30 percent to 90 percent...
