In order to create a model for epiphyseal growth plate transplantation by microvascular technique, a well-defined donor site was established. Dissection of latex-injected adult and juvenile dogs established the vascular supply to the proximal canine fibula. By isolating 7 cm of proximal fibula on the popliteal vessels, the nutrient supply to the epiphyses, metaphysis, and diaphysis is retained. This preserves the nutrient arterial supply to the fibula originating from the cranial tibial artery, the caudal tibial artery, and the small blood vessels from these to the epiphysis. Perfusion of the graft through the defined vascular pedicle was confirmed using 141Ce-labeled microspheres. These results showed a perfusion of the established graft that was as great as or greater than the control, unoperated side. It is concluded that the technique described for isolation can be used for developing a model for vascularized transplantation of epiphyseal growth cartilage in canines.
为了通过微血管技术创建一个骺生长板移植模型，建立了一个明确的供体部位。对注射乳胶的成年和幼年犬进行解剖，确定了犬近端腓骨的血管供应。通过在腘血管上分离出7厘米的近端腓骨，保留了对骨骺、干骺端和骨干的营养供应。这保留了源自胫前动脉、胫后动脉以及从这些动脉到骨骺的小血管对腓骨的营养动脉供应。使用141Ce标记的微球证实了通过确定的血管蒂对移植物的灌注。这些结果表明，所建立的移植物的灌注与未手术的对照侧一样大或更大。得出的结论是，所描述的分离技术可用于开发犬骺生长软骨血管化移植的模型。
