Abstract
A method of forming a bone composite, comprising: providing bone tissue; grinding said bone tissue to form ground tissue; molding the ground bone tissue into a bone composite; applying a binder to the bone composite; applying a vacuum to the mold, and optionally milling or refining the bone composite to the desired shape. Additionally, bone tissue composites made therefrom are included. The composites may be, for example, a bone pin, screw, or prosthesis.
Claims42
A method of forming a bone composite, comprising:
- (i) providing bone tissue;
- (ii) grinding said bone tissue to form ground bone tissue;
- (iii) transferring said ground bone tissue into a mold and compacting said ground bone tissue while maintaining canals within said around bone tissue to form a bone composite;
- (iv) applying a binder to the bone tissue to set within said ground bone tissue and to partially fill the canals of said around bone tissue;
- (v) applying a vacuum to the mold concurrently with step (iv) to substantially evenly disperse the binder throughout said ground bone tissue;
- and
- (vi) optionally milling or refining the bone composite to the desired shape.

A method of forming a bone composite, comprising:
- (i) providing bone tissue;
- (ii) grinding said bone tissue to form ground bone tissue ranging in size from about 125 microns to about 850 microns;.
- (iii) hydrating and transferring said ground bone tissue into a mold and compacting said ground bone tissue while maintaining voids within said around bone tissue to form a bone composite;
- (iv) applying a cyanoacrylate binder to the bone tissue to set within said ground bone tissue and to partially fill the voids of said around bone tissue;
- (v) applying a vacuum to the mold concurrently with step (iv) to substantially evenly disperse the cyanoacrylate binder throughout said ground bone tissue;
- (vi) applying a compressive force of less than 1000 psi to the mold to compact said ground bone tissue;
- and
- (vii) optionally milling or refining the bone composite to the desired shape.
