Abstract

A rib implant securable to first and second rib portions of a rib. The rib implant can include a body, a first porous stem, and a second porous stem. The body can be configured to span a first rib portion of a rib and a second rib portion of the rib. The first porous stem can extend from the body and the first porous stem can be insertable into a first intramedullary canal of the first rib portion. The second porous stem can extend from the body opposite the first porous stem. The second porous stem can be insertable into a second intramedullary canal of the second rib portion to, together with the first porous stem, secure the first rib portion and the second rib portion.

First claim

The invention claimed is:

1. A rib implant securable to first and second rib portions of a rib, the rib implant comprising:
a body including a first end portion and an opposite second end portion, the body configured to span a first rib portion of a rib at the first end portion and a second rib portion of the rib at the second end portion;
a first stem extending from and extending beyond the first end portion of the body, the first stem being tapered and insertable into a first intramedullary canal of the first rib portion;
a second stem extending from and extending beyond the second end portion of the body opposite the first stem, the second stem being tapered and insertable into a second intramedullary canal of the second rib portion to secure, together with the first stem, the first rib portion and the second rib portion; and
a plate extending from the first end portion substantially parallel to the first stem and extending beyond the body, the plate configured to engage a face of the first rib portion when the first stem is inserted into the first intramedullary canal of the first rib portion.

2. The rib implant of claim 1 , wherein the plate includes a plate bore and the first stem includes a stem bore substantially coaxial with the plate bore.

3. The rib implant of claim 2 , further comprising:
a fastener extendable through the plate bore and the stem bore to secure the first stem and the plate to the first rib portion.

4. The rib implant of claim 2 , further comprising:
a second plate extending from the second end portion of the body substantially parallel to the second stem, the second plate configured to engage a face of the second rib portion.

5. The rib implant of claim 4 , wherein the second plate includes a second plate bore and the second stem includes a second stem bore substantially coaxial with the second plate bore.

6. The rib implant of claim 1 , wherein the plate extends laterally beyond the first stem.

7. A rib implant securable to first and second rib portions of a rib, the rib implant comprising:
a body including a first end portion and an opposite second end portion, the body configured to span a first rib portion of a rib at the first end portion and a second rib portion of the rib at the second end portion;
a first stem extending from the first end portion of the body, the first stem insertable into a first intramedullary canal of the first rib portion;
a second stem extending from the second end portion of the body opposite the first stem, the second stem insertable into a second intramedullary canal of the second rib portion to secure, together with the first stem, the first rib portion and the second rib portion;
a first plate extending from the first end portion substantially parallel to the first stem, the first plate configured to engage a face of the first rib portion when the first stem is inserted into the first intramedullary canal of the first rib portion;
a second plate extending from the second end portion substantially parallel to the second stem, the second plate configured to engage a face of the second rib portion when the second stem is inserted into the intramedullary canal of the second rib portion;
a first flange connected between the body and the first stem, the first flange engageable with the first rib portion; and
a second flange connected between the body and the second stem, the second flange engageable with the second rib portion.

8. The rib implant of claim 7 , wherein the first plate includes a first plate bore and the first stem includes a first stem bore substantially coaxial with the first plate bore.

9. The rib implant of claim 8 , wherein the second plate includes a second plate bore and the second stem includes a second stem bore substantially coaxial with the second plate bore.

10. The rib implant of claim 9 , further comprising:
a first fastener extendable through the first plate bore and the first stem bore to secure the first stem and the first plate to the first rib portion; and
a second fastener extendable through the second plate bore and the second stem bore to secure the second stem and the second plate to the second rib portion.

11. The rib implant of claim 7 , wherein the first plate extends from an outer portion of the first flange away from the second flange, and wherein the second plate extends from an outer portion of the second flange away from the first flange.
