Abstract
An acetabular alignment method and apparatus utilize natural landmarks available on a pelvis to guide the alignment of an acetabular device in connection with the implant of a prosthetic hip joint at an implant site in the pelvis. The acetabular device is engaged with a positioning shaft having a longitudinal shaft axis, and locators are mounted upon the positioning shaft for placement adjacent selected landmarks on the pelvis to orient the shaft axis relative to the acetabular axis of a prepared acetabulum at the implant site in order to place the shaft axis at a prescribed angle of abduction and a prescribed angle of anteversion, thereby orienting the acetabular device at the appropriate angle of abduction and the appropriate angle of anteversion.
