An improved reinforced intradiscal plug includes a mid section having opposing ends, and a rubber, polymeric or elastomeric mid section. The mid section is preferably bounded by a pair of rigid end plates, each positioned against a respective end of the mid section. The mid section in combination with the end plates may assume a generally cylindrical, threaded configuration permitting a screw-in installation. Alternatively, the mid section in combination with the end plates assumes a configuration suitable to an impacted installation. At least the mid section may include seriating or protrusions to hold the plug in position once installed. The end plates are at least partially metallic, with at least one link member passing through the mid section so as to interconnect the opposing end sections. One of the end plates may include a threaded bore, with one end of the link member being threaded to receive the threaded bore of that end plate. According to a further alternative embodiment, the link member, a fastener, and/or the end plate(s) may be advanced, causing the rubber, polymeric or elastomeric section to bulge for a tighter fit within the intradiscal space.
