Patient specific reconstructive glenoid systems and methods

1. A system for repairing a glenoid defect of a specific patient, the system comprising:

an impactor body; and

a patient-specific punch coupled to the impactor body, the patient-specific punch including a patient-specific void corresponding to the glenoid defect;

wherein the impactor body is configured to drive the patient-specific punch into an implant material to form a patient-specific glenoid implant.

2. The system of claim 1 , wherein the patient-specific punch is removably coupled to the impactor body.

3. The system of claim 1 , wherein the implant material comprises a bone puck formed from a resected portion of a humeral head.

4. They system of claim 1 , wherein the patient-specific glenoid implant is configured to be coupled to a base plate that is configured to be coupled to the glenoid.

5. The system of claim 4 , further comprising:

a patient-specific shaping block configured to receive the patient-specific glenoid implant in a shaping void; and

a spacer configured for placement in the patient-specific shaping block, the spacer having a geometry corresponding to the base plate;

wherein the shaping void is configured to match the glenoid defect;

wherein the patient-specific glenoid implant is configured to be impacted such that the shaping void and the spacer shape the patient-specific glenoid implant to repair the glenoid defect.

6. The system of claim 5 , further comprising:

an impactor head configured to be removably coupled to the impactor body.

7. The system of claim 5 , wherein the patient-specific shaping block further includes a cover, the cover configured to receive a guide pin.

8. The system of claim 5 , further comprising a base plate reamer configured to ream the patient-specific glenoid implant to match features of the base plate.

9. The system of claim 1 , wherein the patient-specific punch includes knifed edges.

10. A system for repairing a glenoid defect of a specific patient, the system comprising:

a patient-specific punch including a patient-specific void corresponding to the glenoid defect, the patient-specific punch configured to form a patient-specific glenoid implant; and

a patient-specific shaping block configured to receive the patient-specific glenoid implant in a shaping void that matches the glenoid defect;

wherein the patient-specific glenoid implant is configured to be impacted such that the shaping void shapes the patient-specific glenoid implant to fill the glenoid defect.

11. The system of claim 10 , further comprising:

a base plate configured to be coupled to the patient-specific glenoid implant for implantation in the specific patient.

12. The system of claim 11 , further comprising:

a spacer configured to be inserted into the patient-specific shaping block, the spacer having a geometry corresponding to the base plate.

13. The system of claim 10 , further comprising:

a bone cutter configured to form a bone puck, wherein the patient-specific punch is configured to impact the bone puck to form the patient-specific glenoid implant.

14. The system of claim 13 , wherein the bone cutter comprises:

an extraction block configured to receive a humeral head resection;

a fastener configured to extend through the humeral head resection; and

a rotatable blade assembly configured to be received by, and rotate around, the fastener to cut the humeral head resection to form the bone puck.

15. The system of claim 10 , further comprising:

an impactor body comprising an attachment portion configured to be removably coupled to one or more attachments, wherein the patient-specific punch is configured to be removably coupled to the attachment portion of the impactor body.

16. The system of claim 15 , further comprising:

an impactor head attachment configured to be removably coupled to the attachment portion of the impactor body.

17. A method for repairing a glenoid defect of a specific patient, the method comprising:

driving a patient-specific punch into an implant material to create a patient-specific glenoid implant, wherein the patient-specific punch includes a patient-specific void corresponding to the glenoid defect;

placing the patient-specific glenoid implant in a patient-specific shaping block including a shaping void that matches the glenoid defect; and

impacting the patient-specific glenoid implant, such that the patient-specific shaping block shapes the patient-specific implant to fill the glenoid defect.

18. The method of claim 17 , further comprising:

forming the bone puck from a resected portion of a humeral head.

19. The method of claim 17 , further comprising:

reaming the patient-specific implant to accommodate a base plate.

20. The method of claim 19 , further comprising:

coupling the patient-specific glenoid implant to the base plate that is configured to be coupled to the glenoid.
