Crus vascularization in case of substitution of diaphysial defect of tibia by means of proximal fractured fragment lengthening have been studied by anatomo-functional methods in the experiment with 16 dogs. The results of the experiment demonstrated unequal increase of crus blood-filling with localization of the maximum vascularization zone in the projection of a distraction regenerate, displaced fragment and adjoining bone ends. Increase of the operated segment vascularization was caused by dilatation of circulatory channel and formation of new vessels in tissues, subjected to distraction. Tissue hypervascularization in case of distraction of the osseous fragments in defect is a natural reaction, attending prolonged osteogenesis and is preserved till organ-like restructuring of newly formed bone.
通过对16只犬进行实验，采用解剖功能学方法研究了利用胫骨近端骨折块延长替代胫骨干缺损时小腿的血管形成情况。实验结果表明，小腿血液灌注增加不均，最大血管化区域位于牵张再生区、移位骨折块及相邻骨端的投影处。手术节段血管化增加是由于循环通道扩张以及受牵张组织中形成新血管所致。在骨缺损处骨块牵张时组织血管过度增生是伴随长时间骨生成的一种自然反应，并一直持续到新形成骨的类器官重构阶段。
