Claims53
A surgically implantable bone prosthesis other than a carpal bone prosthesis comprising:
- one or more biocompatible, medically inert body members contoured to resemble the shape of a bone, bones, or a portion of a bone or bones which are to be replaced by the prosthesis;
- and
- at least two ligamentous means for restraining the one or more body members along at least two crisscrossing axes which pass through each body member, and cross within the body member the body member or members including at least one channel passing therethrough, positioned along at least one of the crisscrossing axes.
A method for replacing a damaged bone or portion of a bone in a synovial or diarthroidal joint comprising:
- removing the damaged bone or portion of a bone;
- positioning a biocompatible, medically inert body member contoured to resemble the shape of the bone which it is to replace at the site formerly occupied by the damaged bone, the body member having at least two crisscrossing channels which cross within the body member;
- and
- restraining the body member along at least two axes passing through the channels.
A surgically implantable bone prosthesis comprising:
- a biocompatible, medically inert body member contoured to resemble the shape of the bone which it is to replace;
- and
- means for restraining the body member along crisscrossing axes which pass through the body member,
- the body member including at least two channels passing therethrough along the axes and the restraining means comprising ligamentous means passing through the channels.
A method for replacing a damaged bone in a human with a bone prosthesis comprising:
- removing the damaged bone;
- positioning a biocompatible, medically inert body member contoured to resemble the shape of the bone which it is to replace at the site formerly occupied by the damaged bone, the body member having at least two crisscrossing channels which cross within the body member;
- and
- permanently restraining the body member along at least two axes passing through the crisscrossing channels.
A three component total wrist arthroplasty comprising:
- a proximal component adapted to be rigidly affixed to the radius;
- a distal component adapted to be rigidly affixed to the remaining distal carpus and metacarpals;
- and
- a middle component having at least two crisscrossing channels passing therethrough and means passing through the channels for suspending and restraining the middle component between the proximal and distal components.
A surgically implantable bone prosthesis comprising:
- one or more biocompatible, medically inert body members contoured to resemble the shape of a bone, bones, or a portion of a bone or bones which are to be replaced by the prosthesis, with selected areas of the body members having means for ingrowth adhesion;
- and
- means for restraining the one or more body members along at least two crisscrossing axes which cross within the body member, the body member or members including at least one channel passing therethrough, positioned along at least one of the crisscrossing axes.
A surgically implantable b,one prosticsis comprising:
- one or more biocompatible, medically inert body members contoured to resemble the shape of portions of a bone or bones which are to be replaced by the prosthesis;
- and
- means for restraining each of the one or more body members along at least two crisscrossing axes, with at least one of the crisscrossing axes passing through each body member and with a channel in the body member positioned along the at least one of the crisscrossing axes;
- and
- wherein at least one of the crisscrossing axes passes through the remaining portion of the bone and the at least two crisscrossing axes cross within the remaining portion of the bone and/or within the body member.
