Abstract

The present invention relates to orthopedic implants made from a mesh material. The mesh material can be treated in order to promote bone growth, to provide antibiotics, or to provide other beneficial treatment. Specific applications for the implants include, for example, a prosthetic ligament, a tension band, an interbody device, or a fixation device that extends across one or more joints or fractures.

Independent Claims | See all claims (26)

  1. 1. An orthopedic implant for connecting adjacent bone structures, said implant comprising: an interconnecting network of metallic fibers each fiber joined to an adjacent fiber at a juncture, said interconnecting network bounded by a reinforcing band; two or more reinforcing elements extending across a portion of the network adjacent said junctures, each of said reinforcing elements provided to exhibit a tensile strength greater than a selected metallic fiber of the interconnecting network of metallic fibers; and an osteogenic material adhered to at least a portion of the implant, said implant adapted to promote bone ingrowth.
  2. 22. An orthopedic implant comprising: a plurality of metallic fibers interconnected together at junctures to form a network; two or more reinforcing elements extending across a portion of the network adjacent said junctures, each of said reinforcing elements provided to exhibit a tensile strength greater than a selected metallic fiber of the plurality of metallic fibers; an osteogenic material impregnated in said network, wherein said implant is adapted to induce bone fusion between adjacent bone structures.
  3. 23. A method of treating a bone defect, said method comprising: preparing a site of treatment to accept an orthopedic implant; implanting proximal to said site an orthopedic implant comprising an interconnecting network of metallic fibers said interconnecting network bounded by a reinforcing band, and having two or more reinforcing elements secured to said network of metallic fiber, applying an osteogenic material to said implant or to said bone defect to promote bone fusion.
