Methods for treating at least one condition of an intervertebral disc (e.g. protrusion, hemiation, discogenic pain, dehydration, or degeneration) in a patient in need thereof are provided. The method comprises placing a device into an intervertebral space of a patient wherein the device comprises: a chemonucleolysis agent in solid form such that, when the device is placed into the nucleus pulposus of the intervertebral disc, it releases the chemonucleoylysis agent into the nuclear disc tissue surrounding the device to proteolytically degrade the tissue; or first or second active agents in solid form wherein the first active agent is different from the second active agent and wherein the device, when placed in the nucleous pulposus of the intervertebral disc, releases the first and second active agents into the nuclear disc tissue surrounding the device.

A method of treating discogenic back pain in a patient includes the steps of acquiring an image of at least a portion of the patient's spine, locating the spinal disc causing the back pain, and identifying a treatment volume encompassing at least a portion of the spinal disc. The method further includes prescribing a radiation dose to be delivered to the treatment volume, providing a radiation therapy machine, positioning the patient in the radiation therapy machine, programming the radiation therapy machine to deliver the radiation dose to the treatment volume, and delivering the radiation dose to the treatment volume.

A method for treating a patient having discogenic pain includes implanting a neurostimulation lead within an anterior portion of the epidural space adjacent to the posterior longitudinal ligament. A plurality of electrodes is attached to the lead and the lead is implanted with at least a portion of the electrodes facing the posterior longitudinal ligament. The lead may be implanted in the lumbar region of the patient's spine, posterior and parallel to the posterior longitudinal ligament. Electrical stimulation energy applied to the patient through the electrode lead implanted in this manner inhibits the pain signals traveling within the posterior longitudinal ligament. Thus, the applied electrical stimulation energy has an anesthetic effect on the pain fibers adjacent to the posterior longitudinal ligament.

Disc degeneration and chronic back pain are caused by a transport hindrance of oxygen, nutrients and pH buffer from capillaries in endplates into mid-layer of the intervertebral disc. A fluid absorbing conduit is inserted into the intervertebral disc, drawing and delivering the oxygen, nutrients and pH buffer in fluid of body circulation from capillaries at endplates into the mid-layer of the disc. The disc undergoes thousands of relaxation and compression cycles each day from daily activity of the patient. During relaxation phase, the fluid of body circulation containing oxygen, nutrients, and pH buffer is infused into the fluid absorbing conduit. During compression phase, the oxygen, nutrients, and pH buffer in the fluid absorbing conduit is dispersed into the mid-layer of the disc. The pH buffer, bicarbonate, neutralizes the lactic acid to relieve the discogenic pain. Oxygen inhibits hypoxic inflammation and production of lactic acid to further reduce the discogenic pain. Nutrients nourish the disc cells to rebuild or regenerate the disc matrix.Therapeutic agents can be added into the fluid absorbing conduit or injected into the disc implanted with the fluid absorbing conduit to expedite pain relief and disc regeneration. The therapeutic agents can be pH buffering agent, antibiotic, anti-inflammatory drug, anesthetic, antacid, nutrient, sulfate, anti-depressant, calcium channel blocker, growth factor, cells or other.

The present invention relates to a probe and a device for detecting abnormality of an intervertebral disc. More particularly, the present invention relates to a probe and a device for detecting abnormality of an intervertebral disc that gives vibration stimulation to the inner part of the intervertebral disc and obtains an ultrasonic image in order to sense the abnormality of the intervertebral disc causing discogenic pains and inspects whether the intervertebral disc is abnormal by measuring impedance in the intervertebral disc. The present invention provides a probe for detecting abnormality of an intervertebral disc including: a shaft connector; a vibration generator connected to the shaft connector; and an inspector connected to the vibration generator, wherein the vibration generator vibrates the inspector by using a piezoelectric element and a device for detecting abnormality of an intervertebral disc.
