Abstract

The present disclosure provides systems and methods for repairing a defect on a portion of an articular surface of a human body, particularly of the glenoid. More particularly, the present disclosure provides systems and methods for repairing both a glenoid cavity and a glenoid rim of the glenoid using a single implant.

First claim

What is claimed is:

1. A system for repairing a defect on at least a portion of an articular surface of a glenoid, said system comprising:
at least two guide pins, said at least two guide pins comprising a first guide pin and a second guide pin, said first guide pin and said second guide pin configured to be secured to said glenoid;
an excision apparatus comprising a guide body and an excision device;
said guide body comprising a plurality of guide pin sleeves to contain said at least two guide pins, said plurality of guide pin sleeves comprising at least a first guide pin sleeve and a second guide pin sleeve;
wherein, when said first guide pin is contained in said first guide pin sleeve and said second guide pin is contained in said second guide pin sleeve, said guide body is retained in a first excision position for said excision device and;
said guide body further comprises a third guide pin sleeve; and
wherein, when said first guide pin is contained in said first guide pin sleeve and said second guide pin is contained in said third guide pin sleeve, said guide body is retained in a second excision position for said excision device; said guide body is rotatable on at least one of said first guide pin and said second guide pin from said first excision position to said second excision position.

2. The system of claim 1 wherein:
said guide body is slidable along said first guide pin and said second guide pin when said first guide pin is contained in said first guide pin sleeve and said second guide pin is contained in said second guide pin sleeve.

3. The system of claim 1 wherein:
said first guide pin sleeve and said second guide pin sleeve are substantially parallel.

4. The system of claim 3 wherein:
said first guide pin sleeve has a diameter substantially equal to a diameter of said first guide pin and said second guide pin sleeve has a diameter substantially equal to a diameter of said second guide such that, when said first guide pin is contained in said first guide pin sleeve and said second guide pin is contained in said second guide pin sleeve, said first guide pin and said second guide pin are substantially parallel.

5. The system of claim 3 wherein:
said excision device has an axis of rotation which is substantially parallel to said first guide pin sleeve and said second guide pin sleeve.

6. The system of claim 1 wherein:
said first guide pin sleeve and said third guide pin sleeve are substantially parallel.

7. The system of claim 6 wherein:
said first guide pin sleeve has a diameter substantially equal to a diameter of said first guide pin and said third guide pin sleeve has a diameter substantially equal to a diameter of said second guide such that, when said first guide pin is contained in said first guide pin sleeve and said second guide pin is contained in said third guide pin sleeve, said first guide pin and said second guide pin are substantially parallel.

8. The system of claim 6 wherein:
said excision device has an axis of rotation which is substantially parallel to said first guide pin sleeve and said third guide pin sleeve.

9. The system of claim 1 wherein:
said guide body further comprises a fourth guide pin sleeve; and
wherein, when said first guide pin is contained in said first guide pin sleeve and said second guide pin is contained in said fourth guide pin sleeve, said guide body is retained in a third excision position for said excision device.

10. The system of claim 9 wherein:
said first guide pin sleeve and said fourth guide pin sleeve are substantially parallel.

11. The system of claim 10 wherein:
said first guide pin sleeve has a diameter substantially equal to a diameter of said first guide pin and said fourth guide pin sleeve has a diameter substantially equal to a diameter of said second guide such that, when said first guide pin is contained in said first guide pin sleeve and said second guide pin is contained in said fourth guide pin sleeve, said first guide pin and said second guide pin are substantially parallel.

12. The system of claim 10 wherein:
said excision device has an axis of rotation which is substantially parallel to said first guide pin sleeve and said fourth guide pin sleeve.

13. The system of claim 9 wherein:
said guide body is rotatable on at least one of said first guide pin and said second guide pin from said second excision position to said third excision position.

14. The system of claim 1 wherein:
said excision device comprises a rotating cutter.

15. The system of claim 1 wherein:
said excision device is a reamer.

16. A system for repairing a defect on at least a portion of an articular surface of a glenoid, said system comprising:
at least two guide pins, said at least two guide pins comprising a first guide pin and a second guide pin, said first guide pin and said second guide pin configured to be secured to said glenoid;
an excision apparatus comprising a first guide body and an excision device;
said first guide body comprising a plurality of guide pin sleeves to contain said at least two guide pins, said plurality of guide pin sleeves comprising at least a first guide pin sleeve to contain said first guide pin and a second guide pin sleeve to contain said second guide pin;
wherein, when said first guide pin is contained in said first guide pin sleeve and said second guide pin is contained in said second guide pin sleeve of said first guide body, said excision device is positionable on said first guide body at a first of a plurality of excision positions to form a first of a plurality of excision sites and;
said guide body further comprises a third guide pin sleeve; and
wherein, when said first guide pin is contained in said first guide pin sleeve and said second guide pin is contained in said third guide pin sleeve, said guide body is retained in a second excision position for said excision device; said guide body is rotatable on at least one of said first guide pin and said second guide pin from said first excision position to said second excision position.
