Abstract
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…
