摘要： A knee prosthetic system includes a femoral component, a fixed tibial bearing component, a mobile tibial bearing component and an integrated or common tibial base component. The same tibial base component can be used with either the fixed tibial bearing component or the mobile tibial bearing component. The fixed bearing component and tibial base component have mating anti-rotation features. One embodiment of the mobile bearing component does not engage the anti-rotation feature of the tibial base component. Another embodiment engages the anti-rotation feature to allow for limited rotation.

摘要： A hip joint prosthesis comprises a femoral unit and an acetabulum unit. The acetabulum unit has a rigid cap of a material having a low coefficient of friction, defining a cavity which receives the ball head of the femoral unit, and an outer shell having a rigid radially inner part accommodating the cap and a resilient radially outer part anchored in the pelvic bone and radially deformable. For imparting resiliency to the outer part, it may be fractionated into a plurality of finger-like angular sectors each joined to the inner part by an annular zone of reduced thickness. The femoral unit may also be rendered resilient, for instance by locating a plurality of corrugated rings in recesses distributed along the length of its shaft.

摘要： The hip joint socket is formed of a socket body of relatively elastic material, for example of plastic, and one or more reinforcement rings which are shrunk fit on the socket body under a prestress. The rings impart rigidity to the hip joint socket. The rings may protrude from the contour of the socket body or may have projections which protrude from the contour of the socket body in order to improve fixation in a cement bed or pelvic cavity.

摘要： Disclosed herein is an implant assembly including an alignment guide for aligning the engagement between a glenosphere and baseplate via a central screw engaged to the baseplate. The glenosphere includes first and second recess portions. The first recess portion of the glenosphere is configured to engage a tapered side surface of the baseplate and the second recess portion of the glenosphere is configured to engage a portion of a head of the central screw projecting outwardly from a top surface of the baseplate when engaged thereto. The portion of the head of the central screw projecting outwardly from the baseplate is slip-fit into the second recess of the glenosphere. This engagement aids the alignment of the glenosphere and the baseplate and helps to ensure the accurate alignment of the tapered engagement of the side surface of the baseplate and the first recess of the glenosphere.

摘要： The invention provides a modular three-component assembly for replacing a portion of a patient's femur or humerus. A neck component attaches directly to a stem component that inserts into the bone, and a body component that also inserts into the bone is attached to the neck component and/or to the stem component. Methods for assembling the prosthesis are also provided, wherein the stem component is inserted within the body component, and the stem component is joined to the neck component. The prosthesis may be constructed from the components outside of the patient, or, components of the prosthesis may be inserted into the patient prior to final assembly of the prosthesis during surgery.
