Abstract
Various embodiments of implant systems and related apparatus, and methods of operating the same are described herein. In various embodiments, an intermedullary implant for interfacing with a bone structure includes a web structure, including a space truss, configured to interface with human bone tissue. The space truss includes two or more planar truss units having a plurality of struts joined at nodes. Implants are optimized for the expected stress applied at the bone structure site.
Claims20
An implant comprising:
- an intramedullary body, insertable into a medullary cavity of a bone, wherein the body is a solid body having a tapered section with at least one outer contact face on the tapered section;
- and
- a space truss coupled to the at least one outer contact face of the tapered section, wherein, during use, the space truss is at least partially disposed inside the medullary cavity, between the intramedullary body of the implant and the medullary cavity, wherein the space truss comprises two or more planar truss units having a plurality of struts joined at nodes;
- and
- wherein a diameter and/or length of the struts and/or density of the space truss are predetermined such that when the space truss is in contact with the bone at least a portion of strain on the intramedullary body is distributed through the space truss to the bone.
2 more elements
A method comprising:
- forming one or more openings into the medullary cavity of a bone;
- and
- inserting at least a portion of an implant into the medullary cavity of the bone, wherein the implant comprises:
- a solid intramedullary body, insertable into the medullary cavity of a bone, wherein the body has a tapered portion comprising one or more outer contact faces;
- and
- a space truss coupled to at least one of the outer contact faces of the tapered portion, wherein, after insertion, the space truss is at least partially disposed inside the medullary cavity, between the intramedullary body of the implant and the medullary cavity, and wherein the space truss comprises two or more planar truss units having a plurality of struts joined at nodes.
3 more elements
An implant comprising:
- a solid intramedullary body, insertable into a medullary cavity of a bone, wherein the body has a tapered portion comprising one or more outer contact faces;
- a space truss coupled to at least one of the outer contact faces of the tapered portion, wherein, during use, the space truss is at least partially disposed inside the medullary cavity, between the intramedullary body of the implant and the medullary cavity, wherein the space truss comprises two or more planar truss units having a plurality of struts joined at nodes;
- and
- an extra-corporal component which can receive a corresponding connector from a prosthetic device;
- wherein a diameter and/or length of the struts and/or density of the space truss are predetermined such that when the space truss is in contact with the bone at least a portion of strain on the intramedullary rod is distributed through the space truss to the bone.
