Abstract

A method for inserting an acetabular implant into the acetabulum of a patient. The method includes engaging a patient-specific surface of acetabular alignment guide to a complementary rim surface and periacetabular area of a patient. A plurality of alignment pins are inserted through corresponding alignment apertures of the acetabular alignment guide and into the periacetabular area of the patient. The acetabular alignment guide is removed without removing the alignment pins from the patient. An alignment adapter is coupled to an acetabular inserter over the alignment pins and an acetabular implant is implanted using the acetabular inserter.
