Osteoarticular Allogeneic Bone Grafting in Dogs

Abstract

A review of the clinical and pathologic evaluation of allogeneic bone grafts is presented with particular emphasis upon partial joint replacement. The histologic evaluation of cortical bone transplantation is reviewed. Radiographic evaluation of cortical bone transplants is presented in an attempt to understand the normal events that take place in incorporation of the graft by the host. The histologic and radiographic correlation is related to the healing process. Current methods of graft collection and storage are reviewed. While collection of the graft is fairly uniform, there are many varied treatment and storage procedures. General surgical procedures used in performing full cortical bone grafts are reviewed. The clinical use of an osteoarticular allogeneic bone graft in the elbow of a dog is presented, with a review of the operative and postoperative evaluation of the clinical patient.

Results of treatment of subchondral bone cysts in the medial condyle of the equine femur with an autogenous cancellous bone graft

“…Herndam and Chase (1974) (cited by Enneking and Morris 1972), in an experimental study using dogs, demonstrated that the apposition of new bone commences two weeks post transplantation and although the total replacement of the graft takes nine to 12 months, it is indistinguishable radiographically at five months post surgery. Our observations of early radiographic evidence of new bone formation, present six weeks post surgery, are consistent with the findings in dogs by Helphrey and Stevenson (1980).…”
