Shaped bone graft materials and methods of use
A bone material comprising a coherent mass of cartridge milled and demineralized bone fibers is provided, the coherent mass having no binder disposed in or on the coherent mass. In some embodiments, a bone material comprising a lyophilized coherent mass of cartridge milled and demineralized bone fibers is provided, the lyophilized coherent mass having no binder disposed in or on the coherent mass. In some embodiments, a method of making an implantable bone material is provided, the method comprising drying a coherent mass of cartridge milled and demineralized bone fibers, the coherent mass having no binder disposed in or on the coherent mass.
1. A bone material comprising a coherent mass of cartridge milled and demineralized bone fibers, the coherent mass of cartridge milled and demineralized bone fibers having no binder disposed in or on the coherent mass, wherein the bone material is contacted with a liquid to form a putty or a paste that hardens after implantation, wherein the bone material is a cylinder shaped bone material and the coherent mass has a plurality of channels running longitudinally through a center of the cylinder shaped bone material to allow fluid to hydrate the bone material.
2. A bone material of claim 1 , wherein the bone material comprises cortical bone, cancellous bone, cortico-cancellous bone, or mixtures thereof.
3. A bone material of claim 1 , wherein the bone material is obtained from autogenous bone, allogeneic bone, xenogeneic bone, or mixtures thereof.
4. A bone material of claim 1 , wherein the coherent mass is lyophilized.
5. A bone material of claim 1 , wherein the coherent mass has a plurality of channels running longitudinally through an exterior of the cylinder shaped bone material to allow fluid to hydrate the bone material.
