ABSTRACT
Nazht HH, Omar RA, Ahmed HK., Sheep rib xenograft
femoral bone implant in rabbits. Onl J Vet Res., (4):290-299,
2018. We describe a femur bone implant for rabbits using
sheep preserved rib bone graft. A transverse diaphyseal
femoral bone fracture to remove 1cm bone was performed aseptically under xylazine-ketamine hydrochloride anesthesia. The empty space
was then filled with an implant of de-proteinized sterile
sheep rib bone. Femoral fragments and implant were fixed with an intramedullary
pin. The fracture was evaluated clinically daily and by radiology at the 1st,
2nd, 4th and 6th week after implant.
Histopathology was performed at 6 weeks. Rabbits suffered loss in appetite, and
had difficult gait at the 1st week but normalized by the 2nd
to 6th week. Radiology showed periosteal reaction by the end of the 2nd
week with increase in size density around the bony device by the end of the 4th
week. A bone bridge formed to cover the implant and joined the femoral
fragments by the end of the 6th week. Histopathology done at the end
of the 6th week showed partial incorporation of implant with femoral
bone, trabecular bone formation of both mature and immature woven bone and
spaces filled with vascular connective tissue with active osteoblasts lining
the surface of the trabecular bone formation.
Key words: Xeno bony implantation, Intramedullary pinning.
