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.
