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. 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. An acetabular guide system for placing a guide pin near an acetabulum, comprising: an exterior curved surface of an acetabular guide configured with a geometry to substantially match the acetabulum of a specific patient based on a geometry of the acetabulum of the specific patient;a central post
1. An acetabular guide system for placing a guide pin near an acetabulum, comprising: an exterior curved surface of an acetabular guide configured with a geometry to substantially match the acetabulum of a specific patient based on a geometry of the acetabulum of the specific patient;a central post extending from an interior surface of the acetabular guide;a pin guide defining a tapered guide bore having an internal tapered surface extending from the exterior curved surface; anda pin guide insert having an external tapered surface and defining an insert bore;wherein the pin guide insert is configured to be placed in the tapered guide bore in a pre-selected location relative to the pin guide;wherein the central post and the insert bore are on a guide line when the exterior curved surface is engaged in the acetabulum and the pin guide insert is placed in the tapered guide bore; andwherein the guide line is configured to be aligned with an inferior ischial spine of the specific patient due to the geometry of the exterior curved surface. 2. The acetabular guide system of claim 1, wherein the guide line is defined by a first point on a first longitudinal axis through the central post and a second point on a second longitudinal axis through the pin guide. 3. The acetabular guide system of claim 2, further comprising: the guide pin configured to pass through the insert bore and engage a region of a pelvis superior to the acetabulum on the guide line. 4. The acetabular guide system of claim 3, further comprising: at least one registration hook extending from an acetabulum guide rim;wherein the registration hook is configured to contact near an acetabular rim when the exterior curved surface is engaged in the acetabulum. 5. The acetabular guide system of claim 4, wherein the at least one registration hook is formed to connect with the pin guide. 6. The acetabular guide system of claim 3, further comprising: a viewing passage formed through the exterior curved surface. 7. The acetabular guide system of claim 3, further comprising: a guide inserter having an elongated shaft defining an internal bore;wherein the internal bore of the elongated shaft engages an exterior surface of the central post to move the acetabular guide into the acetabulum. 8. The acetabular guide system of claim 3, further comprising: a second post extending from the internal surface substantially parallel to the central post;wherein the guide inserter includes at least one finger extending out from the elongated shaft to engage the second post. 9. A method of placing a guide pin near an acetabulum with an acetabular guide system, 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;providing a pin guide defining a tapered guide bore exterior to the interior surface and a pin guide long axis; andproviding a pin guide insert having an external tapered surface and defining an insert bore around an insert bore long axis, wherein the pin guide insert is configured to be placed in the tapered guide bore in a pre-selected location relative to the pin guide; andproviding the central post and the insert bore to be on a guide line when placed in the pin guide and when the exterior curved surface is engaged in the acetabulum;wherein the guide line is configured to be aligned with an inferior ischial spine of the specific patient due at least to the geometry of the exterior curved surface. 10. The method of claim 9, further comprising: designing the exterior curved surface and a placement of the pin guide to ensure a pre-selected location and a pre-selected orientation of the insert bore long axis on the guide line when the exterior curved surface of the acetabular guide is engaged in the acetabulum. 11. The method of claim 10, wherein designing the exterior curved surface includes acquiring images of the acetabulum of the specific patient. 12. The method of claim 11, further comprising: forming the exterior curved surface based on the design of the exterior curved surface based on the acquired images of the acetabulum of the specific patient; andforming the pin guide on the exterior curved surface such that the insert bore long axis is on the guide line when the pin guide insert is placed in the pin guide and the exterior curved surface is engaged in the acetabulum.
