摘要：
The present invention relates to treating an inter-vertebral disc, in particular, to a method of treating an inter-vertebral disc by effectively ablating a tissue within a disc, in which herniation of nucleus pulposus occurs.A method of treating an inter-vertebral disc according to one embodiment of the present invention relates to treatment using a guidable electrode to be inserted into an inter-vertebral disc of a patient, in which the treatment comprises a step of inserting a front end of a needle unit from the outside of annulus fibrosus into the inside of the annulus fibrosus, a step of inserting a guidable electrode through the rear of the needle unit, a step of adjusting position of the end of the electrode to be adjacent to a target tissue within the annulus fibrosus, and a step of ablating a tissue within nucleus pulposus by applying electrical energy to the electrode.
