  • Publication number: 20070173948
    Abstract: An acetabular cup assembly can include a cup portion and a bearing. The cup portion can include a porous metal outer layer having a first thickness and a solid titanium inner layer having a second thickness. A mating feature can be formed between the cup portion and the bearing. The bearing can be adapted to be selectively secured to the titanium inner layer. In one example, the bearing is formed of cobalt.

  • Publication number: 20070129809
    Abstract: An acetabular cup assembly implantable at an acetabular socket can include an acetabular cup defining a partially spherical bone engaging surface and having a uniform thickness. A spacer can include a body portion formed of porous metal and define a radial support surface. The porous metal can be adapted to receive bone ingrowth through interstitial space at pores defined therein. The spacer can further comprise a piercing portion adapted to be advanced into the acetabular socket. The spacer can bridge a gap defined between the acetabular socket and the acetabular cup. Filler can be disposed between the acetabular cup and the acetabular socket in areas adjacent to the spacer such that the spacer and the filler collectively define a continuous support surface adapted to support the acetabular cup at the bone engaging surface.

  • Publication number: 20060241781
    Abstract: An orthopedic prosthesis for implantation into a bone of a patient includes a porous metal shell adapted to be affixed within the bone. The porous metal shell includes an outer surface adapted to receive bone ingrowth and an inner surface adapted to engage a liner. The porous metal shell is porous from the outer surface to the inner surface. A non-porous member may be affixed to the porous metal shell. The non-porous member may include a piercing member extending from the outer surface, the piercing member adapted to penetrate the bone in an implanted position. The non-porous member may include spikes or fins. In one example, the piercing member may define a reduced material cross section at an interface with the outer surface of the porous metal shell. The piercing member may be adapted to be broken at the reduced material cross section and removed from the porous metal shell.

  • Publication number: 20060100627
    Abstract: A fixation device for securing tissue to a bone. The fixation device includes an anchor having a hollow body defining a longitudinal passage, and a plug configured to be received in at least a portion of the passage. The body comprises a cylindrical portion and a tapered tip portion. The cylindrical portion comprises a plurality of thin-walled window covers such that after implantation the window covers are resorbed first relative to other portions of the cylindrical portion for defining a plurality of apertures on the cylindrical portion.

  • Patent number: 7033364
    Abstract: An apparatus and method for performing a surgery, especially an Anterior Cruciate Ligament replacement surgery, where a flexible strand insertion rod cooperates with a U-Guide apparatus to insert a flexible strand into a tunnel formed in a bone portion and to guide a drill point to form a tunnel transversely to the tunnel of the insertion rod. The drill point is guided through the insertion rod and the flexible strand is held over the drill point as the transverse tunnel is formed. The insertion rod is then removed from the tunnels formed in the bone and the flexible strand is held looped over the drill point. Subsequently, a soft tissue replacement is affixed to one end of the flexible strand and pulled over the drill point with the other end of the flexible strand. The drill point is then used to pull a cross pin through the transverse tunnel to hold the looped end of the soft tissue replacement in place.

  • Publication number: 20050273003
    Abstract: An apparatus and method for performing a surgery, especially an ACL replacement surgery, where a flexible strand insertion rod co-operates with a U-Guide apparatus to insert a flexible strand into a tunnel formed in a bone portion and to guide a pair of drill points to form a pair of tunnels transversely to the tunnel of the insertion rod. The drill points are guided through the insertion rod and the flexible strand is held over the drill points as the transverse tunnels are formed. The insertion rod is then removed from the tunnels formed in the bone and the flexible strand is held looped over the second drill point. Subsequently, a soft tissue replacement is affixed to one end of the flexible strand and pulled over up to the first drill point with the other end of the flexible strand. The first drill point is then used to pull a cross pin through the transverse tunnel to hold the looped end of the soft tissue replacement in place.
