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 said 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 .
