Researchers develop a polymer sponge to repair broken backs
Researchers at the Mayo Clinic have developed a novel spinal graft that automatically "grows" to the requisite size and shape when implanted. The spongy polymer isn't meant to be a formal replacement like the 3D printed neck bones recently installed by a team from the Prince of Wales Hospital in Sydney. Instead, it's designed to act as a bone graft -- a biodegradable scaffold through which a cancer patient's own bones can regrow after surgery.
