Guide alignment system and method

摘要

An orthopedic device includes a patient-specific acetabular guide that can be used for preparing an acetabulum of a patient to receive an acetabular implant and/or placement of an acetabular prosthesis. The acetabular guide has a body with an outer three-dimensional surface configured to match an acetabulum of a specific patient's hip joint designed from data of the patient's hip joint. The acetabular guide can further include a peripheral annular rim.

1. A method of placing a guide pin near an acetabulum with an acetabular guide system, comprising:
coupling an inserter to a patient specific acetabular guide via a keyed post, wherein the keyed post is fixed relative to the patient specific acetabular guide; moving the patient specific acetabular guide into the acetabulum; rotating the patient specific acetabular guide relative to the acetabulum with the coupled inserter; and determining an alignment of the coupled patient specific acetabular guide with the inserter, including viewing an alignment jig, wherein the alignment jig is associated with the inserter and extends from a shaft of the inserter.
