摘要
本文报告20只羊和20只兔胫骨上干骺端截骨延长的实验结果,并对不同延长速度下延长区骨再生过程进行了讨论。延长区新骨形成快,其骨愈合过程既有膜内成骨又有软骨内成骨,但是以膜内成骨为主。作者通过X线和组织学检查方法,观察了1.0mm/d、1.5mm/d、2.0mm/d和2.5mm/d 4种延长速度下骨再生过程。结果提示用缓慢速度延长(1.0mm/d),其组织创伤反应小,骨再生迅速,且延长段骨小梁的致密度和成熟度均优于快速延长(2.0mm/d或2.5mm/d)。
Proximal metaphyseal osteotomy to lengthen the tibia in 4 lengthening rates (1.0> 1.5,2.0,and 2.5 mm/day)was performed on 20 goats and 20 rabbits.It was found that a relatively slow lengthening rate of 1mm/day was better since it induced less tissue reactions and quicker bony regeneration and created more dense and more mature bony trabeculae in the lengthened zone than the other 3 rates.In addition,it was also found the new bone formation in the lengthened zone of the proximal metaphysis of the tibia proceeded quickly and both intramem-branous and endochondral ossifications contributed to the bone healing process with the former in predominance.
