Adjustable glenoid pin insertion guide
First Claim
1. A system for aligning a guiding pin relative to an anatomic structure, comprising:
- a guiding pin insertion guide for orienting the guiding pin relative to the anatomic structure, the guiding pin insertion guide including a base plate and a pin orientation device coupled to and extending from the base plate, the pin orientation device being movable relative to the base plate; and
an axis alignment device, the axis alignment device including a first surface and a second surface having a plurality of through holes extending between the first surface and the second surface, each of the through holes defining a different alignment axis,wherein one of the through holes is configured to align the guiding pin at an orientation that is substantially aligned with a patient-specific alignment axis,the guiding pin insertion guide is configured to receive the guiding pin when the guiding pin is mated with one of the through holes to align the guiding pin insertion guide along the patient-specific alignment axis relative to the base plate, andthe guiding pin insertion guide is configured to be fixed to the base plate along the patient-specific alignment axis.

Abstract
A system and method for aligning a guiding pin relative to a glenoid including a guiding pin insertion guide for orienting the guiding pin relative to the anatomic structure and an axis alignment device. The guiding pin insertion guide includes a base plate and a movable pin orientation device coupled to and extending from the base plate. The axis alignment device has a plurality of through holes that each define a different alignment axis. The guiding pin mates with one of the through holes to align the guiding pin at a patient-specific alignment axis, the guiding pin is then received within the guiding pin insertion guide when mated with the one of the through holes to align the guiding pin insertion guide along the patient-specific alignment axis relative to the base plate, and the guiding pin insertion guide is fixed to the base plate along the patient-specific alignment axis.

12. A system for aligning a guiding pin relative to a glenoid, comprising:
-
a guiding pin insertion guide for orienting the guiding pin relative to the glenoid, the guiding pin insertion guide including a base plate having an upper surface and a glenoid-engaging surface, and a pin orientation device coupled to and extending from the upper surface of the base plate, the pin orientation device being movable relative to the base plate; and at least one axis alignment device, the axis alignment device including a first surface and a second surface having a plurality of through holes arranged in a coordinated array extending between the first surface and the second surface, each of the through holes defining a different alignment axis, wherein one of the through holes is configured to align the guiding pin at an orientation that is at least proximate a patient-specific alignment axis defined by a patient-specific coordinate of the array, the guiding pin insertion guide is configured to receive the guiding pin when the guiding pin is mated with the one through hole to align the guiding pin insertion guide along the patient-specific alignment axis relative to the base plate, and the guiding pin insertion guide is configured to be fixed to the base plate along the patient-specific alignment axis. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method for aligning a guiding pin relative to a glenoid, comprising:
-
determining a patient-specific alignment axis for the guiding pin relative to the glenoid; providing the guiding pin; providing an axis alignment device defined by a member including a first surface and a second surface having a plurality of through holes arranged in a coordinated array extending between the first surface and the second surface, each of the through holes defining a different alignment axis; determining a coordinate location of one of the through holes that defines an alignment axis that most closely corresponds to the patient-specific alignment axis; mating the guiding pin with the one through hole to orient the guiding pin along the patient-specific alignment axis; placing a guiding pin insertion guide over the guiding pin, the guiding pin insertion guide including a base plate having an upper surface and a glenoid-engaging surface, and a pin orientation device coupled to and extending from the upper surface of the base plate, the pin orientation device being movable relative to the base plate such that when the guiding pin insertion guide is placed over the guiding pin, the pin orientation device is aligned along the patient-specific alignment axis; fixing the pin orientation device aligned along the patient-specific alignment axis relative to the base plate; removing the guiding pin along with the guiding pin insertion device from the axis alignment device; contacting the glenoid-engaging surface of the base plate with the glenoid; and securing the guiding pin to the glenoid along the patient-specific alignment axis. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
