Abstract
A prosthetic intervertebral disc is disclosed which can be implanted in the human skeleton, and which can act as a scaffold for regrowth of intervertebral disc material. The disc includes a dry, porous, volume matrix of biocompatible and bioresorbable fibers which may be interspersed with glyscosaminoglycan molecules. The matrix is adapted to have in vivo an outer surface contour substantially the same as that of a natural intervertebral disc, whereby the matrix establishes an at least partially bioresorbable scaffold adapted for ingrowth of intervertebral fibrochondrocytes. Cross-links may be provided by a portion of the GAG molecules.
