ABSTRACT
Bone grafting procedures are used for a variety of purposes ranging from spinal fusion to reconstructive surgery. Spinal fusion is the most common bone grafting procedure conducted in the United States, comprising some 50% of the estimated half-million bone grafting procedures performed annually [1]. It is estimated that worldwide over two million bone grafting procedures are performed annually [2]. As the demand for these procedures continues to increase, it will place a strain on the limited supply of graft material.
