Histologic evidence of cortical allograft bone incorporation in revision hip surgery.

There is no published evidence concerning the histology of cortical allograft bone implanted during revision arthroplasty surgery. Five cases are reported in which cortical allograft bone had been used where biopsies were available between 2 and 27 months after implantation. All cases showed favorable histologic features, with soft tissue attachment by fibrous adhesion, union of graft to host, and osseous remodeling.
