Abstract
An orthopedic device includes a patient-specific acetabular guide that may be used for preparing an acetabulum of a patient to receive an acetabular implant. 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 may further include a peripheral annular rim.

A method of placing a guide pin near an acetabulum with an acetabular guide system, the method comprising:
- positioning an exterior curved surface of an acetabular guide in an acetabulum, where the exterior curved surface has a geometry that substantially matches the acetabulum of a specific patient based on a geometry of the acetabulum of the specific patient;
- interconnecting a pin guide to a central post extending from an interior surface of the acetabular guide, wherein the pin guide includes a guide boss engageable with and rotatable relative to the central post and a guide body extending from the guide boss and operable to move relative to the guide boss;
- rotating the pin guide about the central post to position the guide body of the pin guide relative to the central post;
- selecting a position of the guide body relative to the central post and rotating the guide body to the selected position;
- and
- resting a portion of the pin guide on a selected rim portion of the acetabular guide corresponding to the selected position.
A method of providing an acetabular guide system for placing a guide pin near an acetabulum, the method comprising:
- providing an exterior curved surface of an acetabular guide to have a geometry to substantially match the acetabulum of a specific patient based on a geometry of the acetabulum of the specific patient;
- providing a central post extending from an interior surface of the acetabular guide along a post long axis;
- and
- providing a pin guide configured to be connected to the central post to rotate about the central post to position a guide body of the pin guide relative to the central post, wherein a portion of the pin guide is configured to rest on a selected rim portion of the acetabular guide.
