Abstract
In one embodiment of the disclosure, a prosthetic bone implant includes a prosthesis and a tissue attachment structure connected to the prosthesis. The tissue attachment structure includes a connective structure connected to the prosthesis and an interface structure connected to the connective structure. The interface structure is configured for attachment of tissue thereto. When the interface structure is subject to tension, the connective structure changes in shape.
Claims9
A prosthetic bone implant comprising:
- a prosthesis;
- and a tissue attachment structure connected to the prosthesis, the tissue attachment structure comprising:
- a connective structure having a longitudinal dimension extending from a first end to a second end opposite the first end, the first and second ends of the connective structure being immovably connected to first and second attachment locations on the prosthesis, respectively, and at least part of the connective structure being separate from the prosthesis in between the first and second ends, at least a portion of the connective structure being continuous between the first end and the second end;
- and an interface structure connected to the connective structure at a first location on the interface structure and at a second location on the interface structure separate from the first location, the interface structure being positioned on a single side of a first plane coextensive with a central longitudinal axis of the connective structure along the longitudinal dimension, the interface structure configured for attachment of tissue thereto, wherein a length of the interface structure along a first direction parallel to the central longitudinal axis is less than a length of the prosthesis along the first direction, wherein the connective structure changes in shape when the interface structure is subject to tension, and wherein the first and second ends of the connective structure are separate from the first and second locations on the interface structure, and wherein the connective structure is connected to the prosthesis at the first and second attachment locations when the interface structure is subject to tension and when the interface structure is not subject to tension.

A prosthetic bone implant comprising:
- a prosthesis;
- and
- a tissue attachment structure connected to the prosthesis, the tissue attachment structure comprising:
- a connective structure including a first spring, the first spring being connected to the prosthesis and having a longitudinal dimension extending from a first end to a second end opposite the first end;
- and
- an interface structure connected to the first spring at a first location on the interface structure and at a second location on the interface structure separate from the first location, the interface structure being positioned on a single side of a first plane coextensive with a central longitudinal axis of the first spring of the connective structure along the longitudinal dimension, the interface structure being configured for attachment of tissue thereto,
- wherein a length of the interface structure along a first direction parallel to the central longitudinal axis is less than a length of the prosthesis along the first direction,
- wherein the connective structure changes in shape when the interface structure is subject to tension, and
- wherein the first and second ends of the first spring are connected to the prosthesis at fixed locations on the prosthesis, the first spring remaining connected to the prosthesis at the fixed locations irrespective of a degree of tension applied to the interface structure.
