If you had a nail in your ankle...

You'd want THIS nail (because it stretches!)

If you were to undergo surgery to fuse together bones in your ankle, you'd be facing some pretty poor odds. Such procedures fail two out of every three times.

The main reason is the standard hardware inserted in ankle fusion surgeries. It's a rigid nail that often ends up separating bones rather than keeping them together.

But Georgia Tech startup MedShape — which received seed funding from GRA Ventures — invented a metal alloy that actually stretches and recovers. This alloy is at the core of DynaNail, a new approach to ankle fusion surgery.

This first video in GRA's "Breakthrough" series shows the impact that MedShape's invention has on a common procedure.
