Abstract
Connective tissue-to-bone interface scaffolds (e.g., ligament-to-bone interface scaffolds, tendon-to-bone interface scaffolds, etc.). These scaffolds may be a single integrated implant or may be a modular (e.g., two-part) implant system.
Claims20
A flexible, compressible and compliant graft body having a length, a width and a thickness, wherein the thickness is between 4 mm and 6.5 mm and is less than half the length and half the width, the body further comprising:
- a first layer of porous demineralized bone extending the length and width of the body;
- and
- a second layer of porous mineralized bone extending along an outer surface of the body that is continuously adjacent to the first layer, wherein the second layer has a constant thickness;
- wherein the body has a density that is less than 2.6e-4 g/mm3.
A flexible, compressible and compliant graft comprising a of bone forming a body having a length, a width and a thickness, wherein the thickness is between 4 mm and 6.5 mm and is less than half the length and half the width, the body further comprising:
- a first layer of porous demineralized bone extending the length and width of the body;
- and
- a second layer of porous mineralized bone extending along an outer surface of the strip that is continuously adjacent to the first layer, wherein the second layer has a thickness that varies by less than 10% along the entire second layer;
- wherein the body had a density that is less than 2.6e-4 g/mm3 and a mean bending thickness that is less than about 1.2 mNm.
