Researchers develop new two-step technique to heal herniated disc

ITHACA, N.Y. - Researchers have developed a  new two-step technique to repair herniated discs uses hyaluronic acid gel to re-inflate the disc and collagen gel to seal the hole. The new procedure of repairing ruptured discs resembles repairing a flat tyre.

After a rupture, a jelly-like material leaks out of a herniated disc, causing inflammation and pain. The injury is usually treated one of two ways: a surgeon sews up the hole, leaving the disc deflated; or the disc is refilled with a replacement material, which doesn't prevent repeat leakages. Each approach on its own isn't always effective.

A collaboration led by Cornell University professor Lawrence Bonassar combined these two methods into a new two-step technique that results in a "patched" disc that maintains mechanical function and won't collapse or deteriorate.

"This is really a new avenue and a whole new approach to treating people who have herniated discs," Bonassar said.

"We now have potentially a new option for them, other than walking around with a big hole in their intervertebral disc and hoping that it doesn't re-herniate or continue to degenerate. And we can fully restore the mechanical competence of the disc."
