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.

No. 12/103,834 filed on Apr. 16, 2008, now U.S. Pat. No. 7,967,868 issued on Jun. 28, 2011, which claims the benefit of U.S. Provisional Application No. 60/912,178 filed on Apr. 17, 2007.
Referring to FIG. 13, when the femoral head 92 is salvageable and need not be resected and replaced, the diseased or defective surface of the femoral head 92 can be identified in the image. A femoral component 600 can be designed to replace the defective portions, such as poor bone quality and/or avascular regions of the femoral head 92. The femoral component 600 can include a dome-shaped portion or dome 602 with an outer convex articulating surface 603 for articulating with an acetabular implant or the patient's natural acetabulum and an inner bone engagement surface 604 that is designed to match and be complementary and match the surface of the femoral head 92 with or without soft tissue attached, as determined in the pre-operative plan. The dome 602 can have a periphery 608 designed such that the dome covers and resurfaces all the defective portions of the femoral head 92. The femoral component 600 can have a short stem 606, which is inserted through the femoral head 92 and secured into the femoral neck 94. The stem 606 can be designed during the preoperative plan based on the three-dimensional reconstruction of the patient's anatomy from the patient's scans such that the axis of the stem D is placed in a selected position and orientation relative to the neck 94 of the patient's and in a selected anteversion orientation relative to the proximal femur 90. Additionally, the length of the stem 606 and the size and shape of the cross-section 607 along the length of the stem 606 can also be designed based on the preoperative plan and the reconstruction model of the neck 94 of the patient, such that bone preservation and adequate attachment support are balanced and/or optimized for the particular patient.
Referring to FIGS. 14A and 14B, a patient-specific femoral implant 618 for a proximal femur in which the femoral head 92 is resected can include a femoral head component 620, a femoral neck component 624 and a femoral stem component 622. The femoral implant 618 can be designed during the preoperative plan based on the three-dimensional reconstruction of the patient's anatomy from the patient's scans such that the femoral head implant 620 and femoral neck component 624 cooperate to retain the axis D and the center of rotation R of the patient's femur or acetabulum, based on surgeon determination and preference. The femoral neck component 624 can be designed to match the patient's femoral neck 94 in size and orientation. The femoral stem implant 622 can be selected from standard (non custom) stem sizes) or can be customized for length, cross-section and/or shape for the specific patient.
