A method for inserting an acetabular cup into an acetabulum of a patient includes inspecting a preoperative plan including a three-dimensional image of a patient's acetabulum, selecting at least one of a patient-specific anteversion angle and a patient-specific abduction angle, and approving the preoperative plan. The method also includes preparing the patient's acetabulum for implantation, positioning a patient-specific first surface of an acetabular guide around a matched acetabular rim surface of the patient, and inserting an acetabular cup through an opening of the acetabular guide, the opening having a cylindrical inner surface oriented at the selected at least one of the patient-specific anteversion angle and patient-specific abduction angle.
1. A method for inserting an acetabular cup into an acetabulum of a patient, the method comprising: positioning a first surface of an acetabular guide around an acetabular rim surface of an acetabulum of the patient, the first surface preoperatively configured as a mirror surface of the acetabular r
1. A method for inserting an acetabular cup into an acetabulum of a patient, the method comprising: positioning a first surface of an acetabular guide around an acetabular rim surface of an acetabulum of the patient, the first surface preoperatively configured as a mirror surface of the acetabular rim surface of the patient from a three-dimensional image of the acetabulum of the patient, the acetabular guide including an aperture having an inner surface oriented at preoperatively determined and patient-specific anteversion and abduction angles relative to the first surface;coupling an acetabular cup to a distal portion of an acetabular inserter;contacting an outer surface of a guide-engaging portion of the acetabular inserter to the inner surface of the acetabular guide, the outer surface preoperatively configured to mate with the inner surface at the patient-specific anteversion and abduction angles; andseating the acetabular cup to the acetabulum at the selected anteversion and abduction angles. 2. A method for inserting an acetabular cup into an acetabulum of a patient, the method comprising: positioning a first surface of an acetabular guide around an acetabular rim surface of an acetabulum of the patient, the first surface preoperatively configured as a mirror surface of the acetabular rim surface of the patient from a three-dimensional image of the acetabulum of the patient, the acetabular guide including an aperture having an inner surface oriented at preoperatively determined and patient-specific anteversion and abduction angles relative to the first surface;coupling an acetabular cup to a distal portion of an acetabular inserter;contacting an outer surface of a guide-engaging portion of the acetabular inserter to the inner surface of the acetabular guide, the outer surface preoperatively configured to mate with the inner surface at the patient-specific anteversion and abduction angles; andseating the acetabular cup to the acetabulum at the selected anteversion and abduction angles,wherein coupling the acetabular cup to the distal portion of the acetabular inserter includes rotating the acetabular cup relative to the inserter. 3. The method of claim 2, further comprising: impacting the acetabular inserter. 4. The method of claim 3, further comprising: determining a depth of impaction of the acetabular cup. 5. The method of claim 4, wherein determining the depth of impaction of the acetabular cup includes aligning a planar portion of the guide-engaging portion of the acetabular inserter relative to the first surface of the acetabular guide. 6. The method of claim 4, wherein determining the depth of impaction of the acetabular cup includes impacting the acetabular inserter to a depth determined by depth indicia marked on the acetabular inserter. 7. The method of claim 6, wherein the depth indicia are provided on the guide-engaging portion of the acetabular inserter. 8. The method of claim 3, wherein impacting the acetabular inserter includes impacting a proximal impaction surface of a handle of the acetabular inserter. 9. The method of claim 2, wherein the inner surface of the acetabular guide and the outer surface of the guide-engaging portion of the acetabular inserter are cylindrical. 10. A method for inserting an acetabular cup into an acetabulum of a patient, the method comprising: positioning a first surface of an acetabular guide around an acetabular rim surface of an acetabulum of the patient, the first surface preoperatively configured as a mirror surface of the acetabular rim surface of the patient from a three-dimensional image of the acetabulum of the patient, the acetabular guide including an aperture having an inner surface oriented at preoperatively determined and patient-specific anteversion and abduction angles relative to the first surface;coupling an acetabular cup to a distal portion of an acetabular inserter;contacting an outer surface of a guide-engaging portion of the acetabular inserter to the inner surface of the acetabular guide, the outer surface preoperatively configured to mate with the inner surface at the patient-specific anteversion and abduction angles; andseating the acetabular cup to the acetabulum at the selected anteversion and abduction angles,wherein coupling the acetabular cup to the distal portion of the acetabular inserter includes aligning a plurality of fingers of an intermediate member with corresponding cut-outs on a peripheral edge of the acetabular cup. 11. The method of claim 10, further comprising engaging a receptacle of the intermediate member with a bushing of the acetabular inserter. 12. A method for inserting an acetabular cup into an acetabulum of a patient, the method comprising: coupling a distal portion of an acetabular inserter to an intermediate member;connecting an acetabular cup to the intermediate member;positioning a first surface of an acetabular guide around an acetabular rim surface of an acetabulum of the patient, the first surface preoperatively configured as a mirror surface of the acetabular rim surface of the patient from a three-dimensional image of the acetabulum of the patient, the acetabular guide including an aperture having an inner surface oriented at preoperatively determined and patient-specific anteversion and abduction angles relative to the first surface;mateably contacting an outer surface of a guide-engaging portion of the acetabular inserter to the inner surface of the acetabular guide at the patient-specific anteversion and abduction angles; andinserting the acetabular cup into the acetabulum at the selected anteversion and abduction angles. 13. A method for inserting an acetabular cup into an acetabulum of a patient, the method comprising: coupling a distal portion of an acetabular inserter to an intermediate member;connecting an acetabular cup to the intermediate member;positioning a first surface of an acetabular guide around an acetabular rim surface of an acetabulum of the patient, the first surface preoperatively configured as a mirror surface of the acetabular rim surface of the patient from a three-dimensional image of the acetabulum of the patient, the acetabular guide including an aperture having an inner surface oriented at preoperatively determined and patient-specific anteversion and abduction angles relative to the first surface;mateably contacting an outer surface of a guide-engaging portion of the acetabular inserter to the inner surface of the acetabular guide at the patient-specific anteversion and abduction angles;inserting the acetabular cup into the acetabulum at the selected anteversion and abduction angles; andcoupling a bushing of the acetabular inserter to a receptacle of the intermediate member. 14.
