Abstract
A hip prosthesis that comprises an acetabular component (1) and a femoral component (21). The acetabular component comprises a shell (2) and optionally a liner (9). The shell has an approximate shape of a hollowed spherical cap, in which the shell comprises one or more magnets (13). The femoral component comprises a stem portion (22), a neck portion (25) that is joined to the stem portion, and a spherical head (28) that is affixed to the neck portion and comprises a spherical magnet (34) that is rotatable within the spherical head. The acetabular component is configured to receive all or a portion of the spherical head of the femoral component. Further, the one or more magnets of the acetabular component and the spherical magnet of the spherical head of the femoral component are oriented to generate an attractive force therebetween.
