摘要： An acetabular prosthesis has a shell component that is implantable within bone and a liner component that is matable to the shell. The shell has a generally convex bone engaging outer surface and a generally concave inner surface. A groove is formed in the inner surface of the shell and extends about at least a portion of the inner circumference of the shell. The liner has an inner concave surface and an outer, convex surface with a shape complementary to and matable within the inner surface of the shell. One or more positive surface features is formed on the outer surface of the liner, adapted for selective mating with the groove of the shell. The liner may be joined to the shell by press fitting the two components together such that the positive surface features engage the groove.

摘要： An acetabular cup having an outer surface elongated in a superior/lateral direction is effective to anatomically transfer load to the acetabulum and reduce the likelihood of bone fracture during implantation into the acetabulum. The outer surface has a first portion defined by a first radius and a second portion defined by a second radius. The second radius is offset from the first radius in superior and lateral directions to elongate the outer surface of the acetabular cup.

摘要： An alignable orthopedic prosthesis system includes a prosthesis and an alignment guide. The prosthesis includes a stem having at least one slot extending along its length. The alignment guide has an alignment body with a guide surface extending from an end thereof, namely a key element formed as a blade for engaging and guiding the slot to orient the prosthesis stem. The alignment body also fits against a machined bone surface so that the blade is positioned in a plane that is oriented to guide the stem smoothly into contact with a recess formed in the bone.

摘要： An acetabular prosthesis has a shell component that is implantable within bone and a liner component that is matable to the shell by a locking member disposed with the shell component. The shell has a generally convex bone engaging outer surface and a generally concave inner surface. A groove is formed in the inner surface of the shell and extends about at least a portion of the inner circumference of the shell. The liner has an inner concave surface and an outer, convex surface with a shape complementary to and matable within the inner surface of the shell. One or more deformable tabs are formed on the locking member, adapted for securing the liner within the shell. The liner may be joined to the shell by press fitting the two components together such that the locking members engages one or more positive surface ridges on the liner.
