摘要:
A modular knee implant system allows a surgeon to select between several different styles of distal femoral implant components and several different styles of stem extensions while also allowing for use of a metaphyseal component. The metaphyseal component can be a universal one that is usable with all of the styles of distal femoral implant components through use of an adapter. A second adapter allows for use of stem extensions with different types of connectors with the metaphyseal component. A separate metaphyseal component could also be provided with a distal Morse taper post to mate with a distal femoral component having a proximal Morse taper bore. The metaphyseal component may have an outer surface that is configured to maximize contact area with the patient's bone, and may have a surface finish over a substantial part of its overall length that is conducive to bone ingrowth.

A customized patient-specific patella resectioning guide is disclosed. The customized patient-specific patella resectioning guide includes a body and a cutting guide coupled to the body. The body includes a customized patient-specific negative contour configured to receive a portion of the posterior side of a patient's patella. The cutting guide may be a captured or non-captured cutting guide. A method for fabricating and using such orthopaedic guides is also disclosed.
摘要:
An acetabular cup and method of securing the acetabular cup to an acetabulum so as to provide a bearing surface for a head portion of a femur is provided. The acetabular cup is shaped to provide a cementless, press-fit into a reamed acetabulum. The acetabular cup is formed of a body having a sidewall defining a radius from a center point of the annular rim to the sidewall wherein the radius increases in length from the apex to said annular rim. The method of securing the acetabular cup first includes reaming the acetabulum with a reamer having a head with a radius of curvature that is less than the radius from the center point to the annular rim of the acetabular cup.
摘要:
A surgical reamer assembly for cutting a planar bone surface. The surgical reamer assembly enables the angle or the level of the cutting of the planar reamer to be adjusted. This adjustment is advantageously provided by the use of an adaptor which is positioned between the base support and the planar reamer.
