摘要
作者通过对30只青山羊胫骨干骺端截骨延长的骨矿含量及组织学研究,初步得出以下结论:(1)缓慢的延长速度(1 mm/d)组织能适应机械牵引力,从而增加延长限度;(2)延长区新骨形成方式可能为软骨内成骨、膜内成骨及纤维组织直接转化成骨3种方式并存;(3)新骨形成的过程大致分为:出血及血肿机化,骨痂形成及新骨改建3个阶段。
The histological changes in tibial lengthening with metaphyseal osteotomy were observed in 30 goats.It was found that (1) slow lengthening rate of 1 mm/day could enable the tissues to adapt the mechanical traction,and consequently the limitation of elongation could be increased;(2) the new bone formed in the lengthened region might be the result of a combined osteogenesis from endochondral,intramembranous,and fibrous tissue ossification;and (3)the osteogenetic process could be distinguished into 3 stages of hemorrhage and organization of the hematocele,callus formaton,and remodelling of the new bones.
