Bracing is less effective in overweight teens with scoliosis
...y. Braces exert their effects on the spine through biomechanical
forces, which need to be of sufficient magnitude to create and sustain curve correction. However, because overweight patients have more and thicker soft tissue and surface area, researchers believe the effects may be compromised. "It's possible that...
Improving bone implant technology
...o this, bioengineers need to determine the optimal biomechanical
situation (for example, amount and timing of weight loading) for bone healing around implants. "The cellular and molecular rules that govern how bone adapts to a loaded or unloaded implant have not been as clearly determined as we would like," said B...
