Method and apparatus for a pin apparatus
First Claim
1. An acetabular guide system for placing a guide pin near an acetabulum, comprising:
- a patient specific acetabular guide including an interior surface and an exterior surface, the exterior surface being configured to have a geometry to register within the acetabulum of a specific patient;
an alignment drill insert configured to be received by the patient specific acetabular guide at a first location, the alignment drill insert having a first longitudinal bore configured to be received concentrically in a guide bore of the patient specific acetabular guide, the guide bore extending exterior to the interior surface;
an anchored drill insert including at least one anti-withdrawal feature, such that the anchored drill insert is configured to be fixed to a boney portion exterior to the acetabulum at a second location a predetermined distance from the first location, the anchored drill insert forming a second longitudinal bore;
an alignment pin configured to be received by the first longitudinal bore; and
a coupler configured to couple the alignment pin to a driver, wherein the coupler is dimensioned to correspond to the predetermined distance between the first location and the second location, such that the driver can place the anchored drill insert at the second location based on the first location of the alignment drill insert.

7. 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 to have a geometry to register within the acetabulum of a specific patient; providing an alignment drill insert having a first longitudinal bore configured to be received concentrically in a guide bore of the patient specific acetabular guide, the guide bore extending exterior to an interior surface of the patient specific acetabular guide to align the alignment drill insert at a first location; providing an anchored drill insert including a second longitudinal bore and at least one anti-withdrawal feature, such that the anchored drill insert is configured to be fixed to a boney portion at a second location a predefined distance from the first location; providing an alignment pin configured to be received by the first longitudinal bore; and providing a coupler configured to couple the alignment pin to a driver, wherein the coupler is dimensioned to correspond to the predetermined distance between the first location and the second location, such that the driver can place the anchored drill insert at the second location based on the first location of the alignment drill insert. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A method for implanting an acetabular implant, comprising:
-
forming a patient specific acetabular guide having an exterior surface with a geometry formed to register within an acetabulum of a specific patient; connecting an alignment drill insert to the patient specific acetabular guide at a first location relative to the acetabulum, the alignment drill insert having a first longitudinal bore configured to be received concentrically in a guide bore of the patient specific acetabular guide, the guide bore extending exterior to the interior surface to align the first drill insert at a first location; removably fixing an alignment pin to a first portion of bone at the first location, the alignment pin being received by the first longitudinal bore; coupling a driver to the alignment pin via a coupler; driving, using the driver, an anchored drill insert, including a second longitudinal bore and an anti-withdrawal feature, into a second portion of bone at a second location, the second location being at a predetermined distance from the first location; and selectively removing the alignment pin from the alignment drill insert. - View Dependent Claims (16, 17, 18, 19, 20)
