Abstract
A composition and methods of making or use thereof include a plurality of fibers forming a shape for augmenting tendon to bone repair. The physical presence of the plurality of fibers provides initial fixation, while the use of an osteoinductive material provides long term enhancement of bone formation around the site of the tendon to bone repair.
Claims21
An implant composition for musculoskeletal repair, the implant composition, comprising:
- a peg portion and a sheet portion, both of which are formed from a plurality of fibers from demineralized bone fibers (DBF), collagen fibers, biocompatible polymer fibers, and/or resorbable polymer fibers,
- wherein the peg portion has a cone or truncated cone shape;
- wherein the peg portion is capable of being into a cavity of the bone;
- wherein the sheet is attached to and surrounds the peg portion;
- and
- wherein the sheet portion has a first side and a second side.
A method for stabilizing placement of an implant composition comprising a peg portion and a sheet portion, the method comprising:
- creating a cavity in a bone located proximal to an area in need of repair;
- and
- placing the peg portion into the cavity in the bone;
- and
- wherein the implant composition comprises:
- a plurality of fibers made from demineralized bone fibers (DBF), collagen fibers, biocompatible polymer fibers, and/or resorbable polymer fibers, the plurality of fibers forming a contiguous shape comprising the peg portion and the sheet portion;
- wherein the peg portion has a cone or truncated cone shape with a distal open or closed end and a proximal open end;
- wherein the sheet portion is attached to and surrounds the proximal open end of the peg portion;
- wherein the sheet portion has a first side and a second side, and
- wherein, during use:
- the first side is in contact with an area on the surface of the bone adjacent the cavity.
