Experimental Use of Kiel Bone after Subtotal Sternectomy in the Dog

Summary

The experimental results of chestwall reconstruction after partial sternectomy are reported. Four Beagle dogs underwent subtotal sternal resection and reconstruction by the implantation of a cortico-spongy bone heterograft, sandwiched between two layers of reabsorbable mesh.

Major postoperative complications were not observed. The implant showed favorable mechanical and biological properties.

Approximately six months after the operation two animals were euthanatized as were the remaining two after 12 months. Pathological examination showed good incorporation of the implanted bone with only partial resorption of its spongiosa.

Compared with autologous bone transplants in humans, sterile bone heterograft seems to afford the same mechanical properties but with significantly reduced surgical trauma.

The experimental results of chest-wall reconstruction after partial sternectomy in four Beagle dogs are reported.
