Bone allografts are unique in that the cellular component is typically removed to minimize their rejection. In addition, they are thoroughly treated to eliminate any possibility of disease transmission. Therefore, allografts can be subdivided according to their source, processing method, or available form. 8

Morselized bone grafts, which are produced mainly from femoral heads, are pieces of trabecular bone of about 1 cm3 (like the croutons in your soup!). They are nibbled by hand using a rongeur or a specially designed bone mill. Bone impaction grafting (figure 1) was developed by Dr. Tom Slooff in .

New Food and Drug Administration guidelines in association with independent agency scrutiny have served to decrease this risk in light of recent publicized reports of infection transmission associated with allograft use. In addition, tissue banks are constantly developing new proprietary techniques for allograft processing and sterilization.

compromised during graft processing. Cortical bone allograft remodeling, a process termed "creeping substitution," occurs when allografts are incorporated into host bone. This is a process by which osteoclasts resorb the mineral content of the allograft thus exposing endogenous growth factors providing the capacity to form new bone.

Fifty patients who had revision femoral components with morselized impacted bone graft were studied in a retrospective, matchedpair analysis. In 25 patients the morselized graft was derived from cortical bone (Group A) and in 25 patients the morselized graft was derived from cancellous bone (Group ...
