Abstract
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.
Claims41
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.
An acetabular guide system for placing a guide pin near an acetabulum, comprising:
- a patient specific acetabular guide, including:
- an exterior surface of the patient specific acetabular guide configured to have a geometry to register within the acetabulum of a specific patient, and
- a keyed central post extending from an interior surface of the patient specific acetabular guide,
- wherein the keyed central post includes an exterior surface that defines a post alignment axis relative to the patient specific acetabular guide;
- and
- a registration guide defining a guide bore extending exterior to the interior surface;
- wherein the post alignment axis is at a fixed location and orientation relative to the registration guide.
A method of placing a guide pin near an acetabulum with an acetabular guide system, comprising:
- providing a patient specific acetabular guide, including:
- forming an exterior surface of the patient specific acetabular guide configured to have a geometry to register within the acetabulum of a specific patient, and
- forming a keyed central post extending from an interior surface of the patient specific acetabular guide,
- wherein forming the keyed central post includes forming an exterior surface that defines a post alignment axis relative to the patient specific acetabular guide;
- and
- forming a registration guide defining a guide bore extending exterior to the interior surface;
- wherein the post alignment axis is formed at a fixed location and orientation relative to the registration guide.
