Abstract
A method of controllably heating the annulus of an intervertebral disc is disclosed. The method comprises the steps of forming an access channel through the annulus of an intervertebral disc while avoiding the nucleus of the intervertebral disc, inserting a light-emitting diffuser into the annulus, and activating the light-emitting diffuser to emit diffuse light while maintaining the light-emitting diffuser within the access channel to raise the temperature of the annulus to a value sufficient to cause a change in the characteristics of the annulus.
