两种骨骺刺激术影响长骨局部生长的实验研究

The effect of local growth in long bones following two different epiphyseal stimulating procedures:an experimental study

目的比较截骨和骨膜切除两种常用骨骺刺激术对兔胫骨局部骨生长的影响。方法将４０只兔分为胫骨上端骨骺线远端２ｍｍ处截骨和上端骨骺线上下１ｍｍ以内骨膜切除两组，经大体骨标本测量、Ｘ线摄片、四环素荧光标记、组织学及电镜观察，进行比较研究。结果骨膜切除术对骨骺生长的刺激作用大于截骨术。结论骨膜切除术可作为治疗儿童膝关节畸形的良好方法。

Objective To study the effect of local growth in long bones of the rabbits following two different epiphyseal stimulating procedures.Methods These were osteotomy in the metaphysis near the proximal tibial epiphyseal plate and hemicirecumferential periosteal excision on the proximal tibial epiphysis. Tibia roentgenography,tetracycline labelling,histological method and electron microscopy were used.Results The local stimulating effect following hemi circumferential periosteal excision was more evident than following osteotomy.Conclusion The procedure of periosteal excision could be good for the treatment of children knee′ deformity.
