Intervertebral disc augmentation and rehydration with superabsorbent polymers
First Claim
1. A method for treating an intervertebral disc having a nucleus pulposus and an annulus fibrosis, using one or more superabsorbent polymers, comprising introducing the superabsorbent polymers into the intervertebral disc space without removing nucleus pulposus or annulus fibrosis material, thereby rehydrating the intervertebral disc space.

Abstract
The embodiments provide a method for treating an intervertebral disc having a nucleus pulposus and an annulus fibrosis, using one or more superabsorbent polymers. Additionally, the embodiments provide a method for bulking up an intervertebral disc having a nucleus pulposus and an annulus fibrosis, using one or more superabsorbent polymers. The methods comprise introducing an amount of the superabsorbent polymers into the intervertebral disc space without removing nucleus pulposus or annulus fibrosis material.
