Oblong acetabular cup

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 s...

Beschreibung
Zusammenfassung:	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.
