NON-SPHERICAL ACETABULAR CUP FOR TOTAL HIP REPLACEMENT

摘要

NON-SPHERICAL ACETABULAR CUP FOR TOTAL HIP REPLACEMENT The device is a prosthetic cup prosthesis providing a surface for articulation of the spherical head of a joint arthroplasty. The articulating surface of the cup is the surface of revolution of an arc intersecting the cup equatorial plane and its polar axis, having a center of curvature translated from the spherical center of the cup, rotated about the cup's polar axis.
