    摘要： 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.

    摘要： A method for treating a cartilage defect can include identifying an area of excessive boney growth on at least one of a femoral head and a femoral neck of a patient where the excessive boney growth area is covered with articular cartilage. A portion of the articular cartilage can be harvested from the identified area of excessive boney growth and an area of cartilage damage in an acetabulum of the patient can be identified. The harvested portion of the articular cartilage can be implanted into the identified area of cartilage damage in the acetabulum.

    摘要： A method of performing hip surgery with a robotic guided system on a patient with femoral acetabular impingement can include identifying the femoral acetabular impingement on the patient. Data related to a proximal femur and an acetabulum of the patient is acquired. A three-dimensional model of at least one of the patient's proximal femur and acetabulum is created based on the data acquired. A location and amount of bone to be removed is determined. Dynamic movement limits of a cutting tool associated with the robotic guided system is set based on the determination. The determined bone of at least one of the proximal femur and acetabulum is removed with the tool while being inhibited from moving the tool outside of the dynamic limit by the robotic guided system.

    摘要： A method and apparatus for reattaching soft tissue to a selected boney structure using a rivet. Generally, a rivet having first portion and a second portion is provided to fully secure a soft tissue in the boney structure. The first portion of the rivet retains the soft tissue via a suture which is threaded through the first portion. The second portion of the rivet has at least one expanding member which engages the boney structure upon contact with the first portion of the rivet. Thus, the soft tissue is fully secured to the boney structure, ensuring proper healing.

    摘要： An orthopedic prosthesis for implantation into a bone of a patient can include a shell, an augment and a securing member. The shell can be adapted to be affixed within the bone and have an outer surface adapted to receive bone ingrowth after implantation. The shell can have an inner surface adapted to engage a liner. An elongated slot can extend between the outer and inner surfaces of the shell. The augment can define a body and have a passage therethrough. The securing member can extend through the passage and the slot. The securing member can be movable between a locked position wherein the augment is precluded from relative movement with the shell and an unlocked position wherein the securing member is adapted to slidably traverse along the slot to locate the augment at a plurality of positions relative to the shell.
