Methods for altering the natural history of degenerative disc disease and osteoarthritis of the spine are proposed. The methods focus on the prevention, or delayed onset or progression of, subchondral defects such as bone marrow edema or bone marrow lesion, and subchondral treatment to prevent the progression of osteoarthritis or degenerative disc disease in the spine and thereby treat pain.

Various embodiments of implant systems and related apparatus, and methods of operating the same are described herein. In various embodiments, an intermedullary implant for interfacing with a bone structure includes a web structure, including a space truss, configured to interface with human bone tissue. The space truss includes two or more planar truss units having a plurality of struts joined at nodes. Implants are optimized for the expected stress applied at the bone structure site.

The present invention relates to an implant consisting of a surface layer consisting of fibres and a matrix, having a first surface and a second surface opposite each other, and having a thickness that is at most 5% of the largest dimension of said surface layer; a porous biodegradable part having a first surface and a second surface opposite each other, wherein its first surface is attached to the second surface of the surface layer and having a thickness of 1-8 mm; and a membrane layer made of collage having a first surface and a second surface opposite each other, wherein its first surface is attached to the second surface of the porous part without covering the edges of the porous part; wherein its first surface is attached to the second surface of the porous part wherein the porous part comprises material selected from the group consisting of bioactive glass, bioactive ceramic, hydroxyapatite, tricalciumphosphate and mixtures thereof.

Intervertebral discs are avascular. Oxygen, nutrients and bicarbonate diffuse from capillaries in cartilaginous endplates into discs to feed and maintain disc cells. As we age, calcified layers form at the endplates, blocking and occluding capillaries. Diffusion zones of oxygen and nutrients in disc become shallow. Cells in mid-layer of the disc suffer chronic anaerobic and starving conditions. Lactic acid is produced. Disc cells die from starvation, causing disc degeneration and forming fissures in annulus. Lactic acid leaks from fissures to the outer annulus of the disc to cause irritation, inflammation and persistent pain. Spirals of filament are implanted into the painful and degenerating disc to draw oxygen, nutrients and bicarbonate from the shallow diffusion zones of the cartilaginous endplates into the mid-layer of the degenerating disc. Oxygen inhibits anaerobic production of lactic acid; nutrients feed disc cells to halt disc degeneration; bicarbonate neutralizes lactic acid in the mid-layer to relieve pain.
