Abstract

A bone void plug includes a plug body that extends along a longitudinal axis between a proximal face and a distal opening and a recessed opening that extends from the distal opening toward the proximal face. The recessed opening is configured to receive a bone void filler.

First claim

What is claimed is:

1. A method, comprising:
positioning a bone void plug relative to a bone void;
inserting a bone void filler into the bone void,
wherein at least a portion of the bone void filler backfills a recessed opening of the bone void plug during the inserting; and
blocking displacement of the bone void filler out of the bone void with a proximal face of the bone void plug.

2. The method as recited in claim 1 , comprising fixating a flexible member to the bone void plug prior to positioning the bone void plug, and wherein inserting the bone void filler includes injecting the bone void filler around the flexible member and into the bone void.

3. The method as recited in claim 1 , comprising:
inserting a guide pin into a bone;
positioning a cannulated drill bit over the guide pin; and
reaming the bone void with the cannulated drill bit.

4. The method as recited in claim 1 , wherein positioning the bone void plug includes pushing the bone void plug into an opening of the bone void.

5. The method as recited in claim 4 , wherein the opening is located at a junction between an exterior surface of a bone and the bone void, and positioning the bone void plug includes positioning a proximal face of the bone void plug so it is flush with the exterior surface.

6. The method as recited in claim 1 , wherein positioning the bone void plug includes screwing the bone void plug into an opening of the bone void.

7. The method as recited in claim 1 , wherein inserting the bone void filler includes inserting a delivery tool through a port of the bone void plug.

8. The method as recited in claim 1 , wherein the bone void extends inside of a bone between an opening and a floor, and positioning the bone void plug includes:
inserting the bone void plug into the opening such that a proximal face of the bone void plug sits flush with an exterior surface of the bone and a plug body of the bone void plug extends in a direction toward the floor and contacts a peripheral wall of the bone void.

9. A method, comprising:
inserting a bone void plug into a bone void of a bone;
after inserting the bone void plug into the bone void, inserting a delivery tool through a port of the bone void plug;
backfilling the bone void with a bone void filler carried by the delivery tool; and
wherein the bone void plug dams the bone void and allows the bone void filler to cure inside the bone without displacing from the bone void.

10. The method as recited in claim 9 , comprising removing the bone void plug from the bone void after the bone void filler has cured.

11. The method as recited in claim 9 , wherein inserting the bone void plug includes positioning the bone void plug such that a proximal face of the bone void plug sits flush relative to an exterior surface of the bone, a plug body of the bone void plug extends toward a floor of the bone void, and the plug body contacts a peripheral wall of the bone void.

12. The method as recited in claim 9 , wherein the bone void filler includes a calcium phosphate bone cement.

13. The method as recited in claim 9 , wherein the bone void filler includes a biologic.

14. The method as recited in claim 9 , wherein inserting the delivery tool includes:
inserting a needle of the delivery tool through the port and through a recessed opening of the bone void plug; and
injecting the bone void filler through the needle and into the bone void.

15. The method as recited in claim 14 , wherein inserting the delivery tool includes inserting the needle through a septum of the bone void plug.

16. The method as recited in claim 9 , wherein the bone void plug includes:
a plug body that extends along a longitudinal axis between a proximal face and a distal opening;
a recessed opening that extends from said distal opening toward the proximal face, the recessed opening configured to receive the bone void filler; and
a port formed through the proximal face and including a passageway and a septum.

17. The method as recited in claim 9 , wherein the bone void plug includes:
a plug body extending between a proximal face and a distal opening;
a recessed opening extending from the distal opening to an inner surface of the proximal face;
a septum received within the port; and
a plurality of protrusions that extend outwardly from the plug body and are configured to engage a bone wall surrounding the bone void.

18. The method as recited in claim 17 , wherein the septum includes a passageway that expands in response to inserting the delivery tool through the septum and contracts in response to removing the delivery tool from the septum.

19. A method, comprising:
inserting a guide pin into a bone;
positioning a cannulated drill bit over the guide pin;
reaming a bone void into the bone with the cannulated drill bit,
wherein the bone void includes a floor and an opening at an opposite end of the bone void from the floor;
removing the cannulated drill bit and the guide pin from the bone;
inserting a bone void plug into the opening of the bone void until a proximal face of the bone void plug is substantially flush relative to an exterior surface of the bone,
wherein the bone void plug includes a recessed opening that extends from a distal opening of the bone void plug to an inner surface of the proximal face,
wherein the bone void plug includes a plurality of protrusions that extend radially outwardly from the bone void plug for augmenting fixation of the bone void plug within the opening;
after inserting the bone void plug into the opening, inserting a needle of a delivery tool through a port and a septum of the bone void plug,
wherein the septum includes an expandable passageway that expands as the needle is inserted through the septum; and
backfilling the bone void with a bone void filler carried by a chamber of the delivery tool;
wherein the bone void plug dams the opening of the bone void and allows the bone void filler to cure or harden inside the bone without becoming displaced from the bone void,
wherein at least a portion of the bone void filler cures or hardens within the recessed opening of the bone void plug.

20. The method as recited in claim 19 , comprising performing a revision repair to the bone after the bone void filler cures or hardens.
