Abstract
A new treatment technique has been developed to relieve the herniated disc symptoms. An Nd:YAG laser is used to vaporize a small volume of the nucleus pulposus and thus regressing the spinal disc. In vitro and in vivo intradiscal pressures are measured before, during and after laserectomy. The results show a significant reduction in intradiscal pressures after laserectomy, as a small volume of the nucleus pulposus is ablated
