我们的实验研究证明,成兔与幼兔的骨膜游离移植都能生成新骨。但成兔的骨膜成骨的能力较幼兔弱。成兔的骨膜较薄,与骨皮质附着紧密,切取比较困难,需要特别注意保护骨膜的生发层。有的学者认为骨膜游离移植后不能成骨,或成年后的骨膜移植不能成离,其主要原因可能就是没有注意到成年动物骨膜的特殊性和骨膜切取技术的重要性。所以,直到近几年尚有认为骨膜游离移植不能成骨或成骨能力很弱的报道。实验研究和临床实践发现,骨膜随年龄的增长而成骨活性减退,在外伤等因素的刺激下,成骨活性可恢复。本实验通过改变受区环境条件,来刺激诱发移植骨膜的成骨活性。用定量分析的方法,研究改变受区环境能否增加移植膜的成骨量,同时比较幼兔和成兔骨膜成骨量的差异。
Our experimental studies have shown that the new bone can be generated by free periosteal transplantation in rabbits and young rabbits. However, the ability of rabbit periosteal osteogenesis is weaker than that of young rabbits. Into the rabbit periosteum thin, closely attached with the cortical bone, cut more difficult, need special attention to protect the periosteal germinal layer. Some scholars believe that periosteal free transplantation can not be osteogenesis, or adult periosteal transplantation can not be separated, the main reason may be that did not notice the particularity of adult animal periosteum and the importance of periosteal resection. Therefore, until recent years there are still considered periosteal free graft osteogenesis or weak ability to report. Experimental research and clinical practice found that the periosteum decreased osteogenic activity with age, stimulated by factors such as trauma, osteogenic activity can be restored. The experiment by changing the environmental conditions of the affected area, to stimulate the osteogenesis induced periosteal graft activity. Quantitative analysis method was used to study whether the change of the surrounding environment can increase the osteogenic volume of the transplanted membrane. Meanwhile, the difference of the osteogenesis volume between the young rabbits and the adult rabbits was compared.
