Collarbones, arms, wrists, hips and ankles are parts of the body most at risk of breakage.
I always think the body is remarkable in how it can heal itself. In children, bones can repair in as little as three weeks.
But sometimes, nature needs a little help, especially if the defect is so severe that a normal approach won’t work.
Now some clever chemical engineers at Massachusetts Institute of Technology (MIT) have devised a new implantable tissue scaffold coated with bone growth factors that are released slowly over a few weeks.
