The principal nourishment to the rib in a free flap is derived from the nutrient artery that pierces the costal head and terminates in the medullary cavity. A question surrounds the adequacy of the periosteal vessels in providing nourishment to the entire bone. A study of the blood supply and bony metabolism in the osseous portion of four free flaps of rib and attached pleura used to reconstruct the laryngotrachea in four dogs was undertaken. A microvascular anastomosis was attached to the anterior intercostal artery. An intact anastomosis was demonstrated in all four animals with fill of the most distal arborization in the bone in three. Technetium Tc 99m scanning, tetracycline labeling, and light microscopy revealed healthy metabolizing bone. The airway in all four animals was widely patent.
游离皮瓣中肋骨的主要营养来源是穿经肋骨头并终止于髓腔的滋养动脉。骨膜血管能否为整块骨头提供充足营养存在疑问。对四只狗用于重建喉气管的四块带肋骨及附着胸膜的游离皮瓣的骨性部分的血液供应和骨代谢进行了研究。将微血管吻合连接到肋间前动脉。四只动物均显示吻合完整，三只动物的骨内最远端分支血管有充盈。锝Tc 99m扫描、四环素标记和光学显微镜检查显示骨代谢健康。所有四只动物的气道均广泛通畅。
