摘要： A modular femoral internal implant system for use in the treatment of femoral disorders resulting from injury, disease or congenital defect includes at least three interconnectable components: 1) an elongated epiphyseal/metaphyseal implant, 2) an intramedullary rod and 3) an angled side plate having an elongated plate portion adapted to be secured to the outer cortical wall and a hollow sleeve adapted to extend into the femur. The epiphyseal/metaphyseal implant can be connected to either the angled side plate or the intramedullary rod. The system may also include an elongated bone plate connectable to the angled side plate, one or more additional epiphyseal/metaphyseal implants of variable length, an additional angled side plate, a distal buttress plate connectable to the elongated bone plate, and a plurality of bone screws of a universal design. Preferably, many or all of the components of the system are made of an inert, resilient titanium-base alloy.

摘要： A device suitable for use in a wide variety of types of joints of the body of a human or other mammal is provided. The device is especially useful for implantation into the human femur so as to repair an anterior cruciate ligament. The device is self-locking and can be used to connect two parts of a joint together by means of an artificial ligament (if desired) or by means of a biological graft (either allegraft or autogenous, including bone with a natural tendon attached thereto). The device permits the surgeon very simply to do a revision from such a mechanical ligament to a biological graft or vice-versa, as desired; that is, the device of the invention is fully revisable. A method of connecting two parts of a joint is also given.

摘要： A prosthetic acetabular cup 100 includes a fixation element 102 for introduction into the acetabulum. The fixation element 102 has a concave inner surface with a generally circular base formed in a plane generally perpendicular to the central longitudinal axis. A bearing component 7 is formed from a deformable material and has a concave opening therein for receiving a spherical head of a prosthetic femoral component. The bearing component 7 has an outer surface that nests within the concave inner surface of the fixation element 102. A snap lock mechanism is used to lock the bearing component 7 within the fixation element 102 in the axial direction. Both the fixation element 102 and the bearing component 7 include a plurality of circumferentially spaced recesses 3, 12 located around a common pitch circle adjacent the generally circular base of the fixation element 102. When aligned, the recesses 3, 12 form a combined recess of predetermined shape for receiving a pin 20 which is inserted therein to prevent relative rotation between the bearing component and the fixation element.

摘要： A novel method for replacing a previously implanted knee joint prosthesis in a patient is disclosed in which the previously implanted femoral component is replaced with a revision femoral component having thicker distal and posterior bearing portions so as to restore the natural anatomic transverse joint plane and collateral ligamentous balance in extension and flexion of the prosthetic joint. Instrumentation for use in this method includes a novel revision cutting jig which is used in the preparation of the distal end of the femur for the implantation of the revision femoral component.

摘要： A compression anastomosis assembly of interlocking coupling members, particularly suitable for use in achieving anastomosis of tubular organs, having an improved locking feature to prevent inadvertent disassembly of installed coupled members. The design and configuration of the members also provide for ease in placement of the assembly in a living body wherein preferably one assembly member includes a cutting guide and a cutting ring which facilitate use of a cutting implement commonly associated with a device suitable for use during assembly implantation.
