Abstract
The invention is a surgically implantable bone and bone joint prosthesis which is designed to be directly attached during surgery and which includes ingrowth receptive zones or stationing sites for delayed ingrowth adhesion naturally over time. The ingrowth receptive zones preferably emulate cancellous bone and are at locations on the body member corresponding generally to the area where connective tissue naturally attaches in vivo.
Claims42
A surgically implantable bone and bone joint prosthesis comprising:
- a body member;
- means for direct immediate attachment of the body member to adjacent connective tissue;
- and
- at least one connective tissue ingrowth receptive stationing site on or in the body member for delayed ingrowth adhesion naturally over time.
A surgically implantable bone and bone joint prosthesis comprising:
- a body member;
- means for direct immediate attachment of the body member to adjacent connective tissue;
- at least one connective tissue ingrowth receptive stationing site on or in the body member for delayed ingrowth adhesion naturally over time;
- and
- ligamentous means to draw connective tissue to the ingrowth surface of the stationing site to achieve buttressing and affixation of the body member to adjacent connective tissue, the ligamentous means being chosen from the group consisting of capsular strips, bone-ligament-bone graft, and tendon.
A surgically implantable bone and bone joint prosthesis comprising:
- a body member;
- means for direct immediate attachment of the body member to adjacent connective tissue;
- and
- at least one connective tissue ingrowth receptive stationing site on or in the body member for delayed ingrowth adhesion naturally over time, the ingrowth receptive zones being treated with humeral growth factors to further induce ingrowth.
A surgically implantable bone and bone joint prosthesis comprising:
- a body member and means for direct immediate attachment of the body member to adjacent connective tissue, the body member including at least one channel with at least one connective tissue ingrowth receptive stationing site for delayed ingrowth adhesion naturally over time at least one of the channel openings so that mooring means in the form of suture or ligamentous means may be passed therethrough to draw connective tissue to the ingrowth receptive surface of the stationing site;
- and ingrowth receptive zones on the walls of the channel to secure the ligamentous means to the prosthesis over time.
A surgically implantable bone and bone joint prosthesis comprising:
- a body member;
- means for direct immediate attachment of the body member to adjacent connective tissue;
- at least one connective tissue ingrowth receptive stationing site on or in the body member for delayed ingrowth adhesion naturally over time;
- and
- mooring means are provided to draw connective tissue to the ingrowth surface of the stationing site to achieve buttressing and affixation of the body member to adjacent connective tissue,
- wherein the mooring means are secured to the periphery of the body member by way of eyelets formed in the surface of the body member.
A surgically implantable bone and bone joint prosthesis comprising:
- a body member;
- at least one ingrowth receptive stationing site on or in the body member for delayed ingrowth adhesion naturally over time;
- and
- mooring means for directly attaching the body member to adjacent connective tissue while drawing the connective tissue to the ingrowth surface to achieve buttressing and affixation of the body member to adjacent connective tissue.
A surgically implantable bone and bone joint prosthesis comprising:
- a body member;
- at least one ingrowth receptive zone on or in the body member for delayed ingrowth adhesion naturally over time;
- and
- ligamentous means for directly attaching the body member to adjacent connective tissue while drawing the connective tissue to the ingrowth surface to achieve buttressing and affixation of the body member to adjacent connective tissue.
A surgically implantable bone and bone joint prosthesis comprising:
- a body member;
- at least one ingrowth receptive zone on or in the body member for delayed ingrowth adhesion naturally over time;
- and ligamentous means chosen from the group consisting of capsular strips, bone-ligament-bone graft, and tendon for directly attaching the body member to adjacent connective tissue while drawing the connective tissue to the ingrowth surface to achieve buttressing and affixation of the body member to adjacent connective tissue.
A surgically implantable bone and bone joint prosthesis comprising:
- a body member;
- means for direct immediate attachment of the body member to adjacent connective tissue;
- at least one connective tissue ingrowth receptive stationing site on or in the body member for delayed ingrowth adhesion naturally over time;
- and
- bone-ligament-bone grafts to draw connective tissue to the ingrowth surface of the stationing site to achieve buttressing and affixation of the body member to adjacent connective tissue.
A surgically implantable bone and bone joint prosthesis comprising:
- a body member;
- means for direct immediate attachment of the body member to adjacent connective tissue;
- at least one connective tissue ingrowth receptive stationing site on or in the body member for delayed ingrowth adhesion naturally over time;
- bone-ligament-bone grafts to draw connective tissue to the ingrowth surface of the stationing site to achieve buttressing and affixation of the body member to adjacent connective tissue;
- and
- pairs of bone-ligament grafts with the bone portions touching.
