A method and an acetabular augment are disclosed for compensating for a deficiency encountered in natural bone at an implant site wherein an acetabular component of a prosthetic hip implant is to be implanted within a prepared acetabulum during a hip arthroplasty. A buttress member of an acetabular augment is placed at a selected angular position relative to an affixation member of the acetabular augment, as determined by a trialing procedure in which a trial buttress member is placed at the deficiency while a trial affixation member is placed upon natural bone at the implant site to determine a trial relative angular position between the trial buttress member and the trial affixation member of a trial acetabular augment located at the implant site. The relative angular position between the buttress member and the affixation member then is selected to mimic the trial relative angular position. The location of the trial acetabular augment is marked, and the trial acetabular augment is removed. The acetabular augment then is secured in place at the implant site, at the marked location, to mimic the location of the trial acetabular augment and place the buttress member at the deficiency, with the affixation member placed upon natural bone at the implant site.
