Porous bone reinforcements

摘要

A method of reinforcing the bone in an acetabulum for receiving a prosthetic acetabular implant includes preparing a surface of the acetabulum to receive an acetabular implant. At least one porous generally cylindrical bone reinforcement element is provided. At least one bore is drilled in an area of the acetabulum receiving the prosthetic acetabular implant for receiving at least one and preferably more reinforcement elements in the form of cylindrical pilings. The cylindrical porous bone reinforcement element is inserted in the bore such that an exposed surface of the porous bone reinforcement element is adjacent the surface of the acetabulum. The acetabular implant is then implanted with an outer surface of the acetabular implant supported by the reinforcement members.

1. A method for reinforcing a prepared bone structure comprising:
obtaining a plurality of individual reinforcement members each having a porous bone contacting surface and an at least partially solid end surface and obtaining a single individual prosthetic joint component having a bone contacting surface; forming a plurality of spaced recesses in a surface of a prepared bone structure for receiving the plurality of reinforcement members, the recesses spaced to leave bone structure surrounding each of the recesses; implanting one of the plurality of reinforcement members in each of the plurality of spaced recesses formed in the bone structure so that the end surface of the reinforcement member is at the bone structure surface; and implanting the single individual prosthetic joint component with the bone contacting surface in contact with the end surface of each of the reinforcement members and in contact with the bone surface surrounding each individual reinforcement member.
