Abstract
An improved prosthetic implant for forming a support structure between adjoining vertebrae in a spinal column. The prosthetic implant includes a generally spherical or ellipsoidal body that at least partially engages a surface of an adjacent vertebrae. The generally spherical or ellipsoidal body can include an opening to receive packing material such as medicine, human tissue and the like. The generally spherical or ellipsoidal body can include a stabilizer to at least partially limit the movement of the prosthetic implant between two vertebrae.
Claims89
A prosthetic implant to at least partially support adjoining vertebrae in a spinal column, comprising a prosthetic implant having a substantially spherical or ellipsoidal body that includes an exterior surface, said exterior surface including at least one non-growth outer surface that at least partially inhibits growth on at least one said non-growth outer surface while positioned between adjoining vertebrae, said substantially spherical or ellipsoidal body being formed of a material designed to maintain a tension load of at least about ten pounds without substantially deforming, less than about 50% of the volume of said substantially spherical or ellipsoidal body constituting one or more cavities.
A prosthetic impart to at least partially support adjoining vertebrae in a spinal column, comprising a prosthetic implant having a substantially spherical or ellipsoidal body that includes an exterior surface, said exterior surface including at least one growth promoting outer area, said growth promoting outer area at least partially promoting tissue growth on said at least one growth promoting outer area while positioned between adjoining vertebrae, said at least one growth promoting outer area including a substantially smooth surface, said substantially spherical or ellipsoidal body being formed of a material designed to maintain a tension load of at least about ten pounds without substantially deforming, less than about 50% of the volume of said substantially spherical or ellipsoidal body constituting one or more cavities.
A prosthetic implant to at least partially support adjoining vertebrae in a spinal column, comprising a prosthetic implant having a substantially spherical or ellipsoidal body and at least one stabilizer positioned at least partially about an exterior surface of said substantially spherical or ellipsoidal body, said substantially spherical or ellipsoidal body being formed of a material designed to maintain a tension load of at least about ten pounds without substantially deforming, less than about 50% of the volume of said substantially spherical or ellipsoidal body constituting one or more cavities, said at least one stabilizer at least partially connected to said exterior surface of said substantially spherical or ellipsoidal body, said at least one stabilizer at least partially limiting the movement of said substantially spherical or ellipsoidal body between said adjoining vertebrae.
