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.

1. An acetabular guide system for placing an alignment pin near an acetabulum, comprising: an acetabular guide, including: an exterior surface of the acetabular guide configured to have a geometry to substantially engage the acetabulum of a specific patient, anda central post extending from an interior surface of the acetabular guide; anda pin guide, including: a guide boss engageable with, and rotatable relative to, the central post of the acetabular guide;a guide body extending from the guide boss operable to move relative to the guide boss;a first arm extending directly from the guide body; anda second arm extending directly from the first arm to the guide boss;wherein the guide body defines a first bore to allow the alignment pin to pass through the guide body and engage a region near the acetabulum, such that the guide boss is configured to disengage the central post while the pin remains engaged with the region near the acetabulum. 2. The acetabular guide system of claim 1, wherein the first arm is configured to articulate longitudinally relative to the second arm to move the guide body a selected distance from the central post. 3. The acetabular guide system of claim 1, wherein a pin axis defined by the first bore is parallel with a guide axis defined by the central post. 4. The acetabular guide system of claim 1, wherein the guide body includes a first guide body defining the first bore and a second guide body defining a second bore. 5. The acetabular guide system of claim 4, wherein the first bore and the second bore are parallel; wherein the first guide body and the second guide body are fixed relative to one another. 6. The acetabular guide system of claim 1, further comprising: an alignment pin configured to pass through the first bore relative to the central post. 7. The acetabular guide system of claim 6, further comprising: an instrument guide configured to engage the alignment pin and defining an instrument guide bore having an internal diameter greater than an external diameter of the alignment pin. 8. An acetabular guide system for placing an alignment pin near an acetabulum, comprising: an alignment guide having: an exterior surface configured to match a specific patient;a central post extending along a guide axis from an interior surface of the alignment guide when the exterior surface is positioned in the specific patient's anatomy; andan upper rim positioned between the interior surface and the exterior surface and including at least a first support portion and a second support portion;a pin guide having: a boss configured to removably engage the central post of the alignment guide to allow the boss to rotate about the central post,a guide body extending from the boss,a first arm connected directly to the guide body, anda second arm connected directly to the boss and directly to the first arm,wherein the first arm is moveable relative to the second arm;wherein the guide body is configured to be moveable relative to the central post of the alignment guide;wherein the guide body defines a central bore configured to receive an alignment pin for coupling to a pelvis; wherein the boss is configured to decouple from the central post of the alignment guide while the alignment pin is coupled to the pelvis. 9. The system of claim 8, wherein the first arm is at least partially received within the second arm. 10. The system of claim 8, wherein the first arm moves along the second arm to vary a distance of the guide body from the boss. 11. The system of claim 10, wherein the boss defines a blind bore to receive at least a portion of the central post. 12. The system of claim 11, wherein the guide axis defined by the central post is parallel with a pin axis defined by the bore in the guide body; wherein the alignment pin is configured to be aligned with the pin axis. 13. The system of claim 11, wherein the boss rotates about the central post and wherein the guide body rotates about the central post due at least to the rotation of the boss. 14. The system of claim 8, further comprising: an instrument alignment guide configured to receive the alignment pin and defining an internal bore having an internal diameter. 15. The system of claim 14, further comprising: at least one of the alignment pin or a secondary alignment pin, wherein each of the at least one of the alignment pin or the secondary alignment pin have an external diameter less than the internal diameter of the instrument alignment guide. 16. The system of claim 15, further comprising: an instrument configured to attach to the instrument alignment guide. 17. An acetabular guide system, comprising: an acetabular guide, including: an exterior surface of the acetabular guide configured to have a geometry to substantially engage the acetabulum of a specific patient, anda central post extending from an interior surface of the acetabular guide; anda pin guide, including: a guide boss engageable with and rotatable relative to the central post of the acetabular guide, anda guide body extending from the guide boss operable to move relative to the guide boss;wherein the guide body defines a first bore to allow the alignment a pin to pass through the guide body and engage a region near the acetabulum, such that the guide boss is configured to disengage the central post while the pin remains engaged with the region near the acetabulum. 18. The acetabular guide system of claim 17, wherein the pin guide further comprises: a first arm extending directly from the guide body; anda second arm extending directly from the guide boss, the first arm and the second arm sharing a longitudinal axis;wherein at least a portion of the first and second arms are coaxial. 19. The acetabular guide system of claim 18, wherein at least a portion of the first arm is configured to be received within the second arm. 20. The acetabular guide system of claim 18, wherein the longitudinal axis is at a fixed angle relative to the acetabular guide.
