Abstract

A hand and/or wrist implant, including a web structure having a space truss with two or more planar truss units having a plurality of struts joined at nodes. The web structure is configured for the repair of traumatic bone fractures.

Claims

1. An implant for interfacing with a bone structure, comprising:

a web structure comprising a space truss comprising two or more planar truss units having a plurality of struts joined at nodes, wherein the web structure is configured to interface with human bone tissue; and

one or more channels formed in the web structure, the one or more channels extending through the web structure and having an channel exit in at least two sides of the web structure.

2. The implant of claim 1, wherein one or more of the channels are defined by one or more circular or arcuate struts coupled to one or more planar truss units.

3. The implant of claim 1, wherein one or more of the channels are defined by channel structure coupled to one or more of the planar truss units.

4. The implant of claim 1, wherein one or more of the channels are substantially tubular.

5. The implant of claim 1, wherein one or more of the channels are substantially threaded, having a threading complementary to the threading of a bone screw fastener.

6. The implant of claim 1, wherein the one or more channels are defined by one or more substantially arcuate and/or circular struts coupled to one or more planar truss units.

7. The implant of claim 1, wherein the plurality of planar truss units comprise one or more planar triangular truss units having three substantially straight struts and three nodes in a triangular configuration.

8. The implant of claim 1, wherein the plurality of planar truss units are coupled to one another such that one or more planar truss units lie in a plane that is not substantially parallel to a plane of a planar truss unit that shares at least one strut with the one or more planar truss units.

9. The implant of claim 1, wherein a plurality of planar truss units define an exterior surface of the web structure.

10. The implant of claim 1, wherein the at least some of the connecting struts define triangular trusses having at least one node shared by two different triangular planar truss units having different corresponding angles.

11. The implant of claim 1, wherein the plurality of planar truss units comprises a first planar triangular truss unit coupled to a second planar triangular truss unit, wherein the first and second planar triangular truss units are coupled in an opposing manner with a single node defining the apex of each planar triangular truss unit.

13. The implant system of claim 10, further comprising an external support couplable to the web structure using one or more of the fasteners, wherein, during use, the external support is couplable to an exterior of the bone structure.

14. The implant system of claim 11, wherein the external support comprises one or more openings that align with one or more of the channels of the implant such that, during use, a fastener may pass through the one or more openings of the external support into one or more channels of the implant.

16. The implant system of claim 11, wherein the external support is an integral part of the web structure.

12. An implant system for interfacing with a bone structure, comprising:

a web structure comprising a space truss comprising two or more planar truss units having a plurality of struts joined at nodes, wherein the web structure is configured to interface with human bone tissue;

one or more channels formed in the web structure, the one or more channels extending through the web structure and having a channel entrance on at least one side of the web structure and a channel exit on at least one different side of the web structure; and

one or more fasteners positionable within the channels, wherein the fasteners couple the web structure to a bone during use.

15. The implant system of claim 12, wherein the external support comprises one or more additional openings that accept a fastener that is used to couple the external support to an external portion of the bone structure.

17-24. -24. (canceled)

25. A method of repairing a bone structure, comprising:

obtaining an implant, the implant comprising;

a web structure comprising a space truss comprising two or more planar truss units having a plurality of struts joined at nodes, wherein the web structure is configured to interface with human bone tissue; and

one or more channels formed in the web structure, the one or more channels extending through the web structure and having an channel exit in at least two sides of the web structure;

passing one or more fasteners into one or more of the channels;

coupling one or more of the fasteners to the bone structure.
