    Abstract: A prosthetic acetabular cup comprising a dome-shaped expandable shell having an annular rim portion (2) and an apex portion and a concave inner cavity extending therebetween for receiving a bearing liner; the shell further comprising an apex aperture (21) centrally disposed in the apex portion relative to a shell axis of rotation and a plurality of radially spaced slots (9) extending from proximal the rim portion to the apex aperture to define a plurality of shell segments expandable outwardly relative to the shell axis about a hinge portion connecting the segments together when an expanding force is applied at the aperture. The present invention provides a simple, correctable and mechanically stable means of inserting and securing a prosthetic acetabular cup in an acetabular bone cavity in a non- intrusive and precisely aligned manner. The present invention also provides a cup for cavities of different sizes/bone properties which further provides a stable and secure platform for an acetabular cup bearing liner to be mounted and secured in.

    Abstract: An orthopedic instrument for installing a new reverse hip prosthesis, particularly the acetabular cup thereof, wherein the cup can be affixed to the pelvis with or without screws. The acetabular cup is releasably attached to the instrument and the instrument is used to position the cup in the pelvis. Optional screw guides are provided in the instrument in case the surgeon wishes to use screws to affix the cup to the pelvis.

    Abstract: Methods and apparatus using a surgical navigation system to position the femoral component of a prosthetic hip during hip joint replacement surgery without separately affixing a marker to the femur. The navigation system acquires the center of rotation of the hip joint as well as at least one point on the femur in the pelvic frame of reference. From these two points, the navigation system calculates the position and length of a first line between the center of rotation of the hip joint and the point on the femur. Optionally, a second point on the femur that is not on the first line is palpated. The system can calculate the position and length of a second line that is perpendicular to the first line and that runs from the first line to the second palpated point on the femur. The prosthetic cup is implanted and its center of rotation is recorded. A tool for forming the bore within which the stem of the femoral implant component will be placed is tracked by the navigation system. While the tool is fixed to the femur, the surgeon re-palpates the same point(s) on the femur that were previously palpated. The navigation system calculates the position and length of a first line between the center of rotation of the prosthetic cup and the re-palpated first point. If a second point on the femur was re-palpated, the navigation system also calculates the position and length of a perpendicular line between the first line and the second point. The surgical navigation system uses this information to calculate and display to the surgeon relevant information about the surgery, such as change in the patient's leg length and/or medialization/lateralization of the joint.
