带血管的骨膜及同种脱钙骨移植治疗骨缺损的实验研究

Experimental Studies on the Restoration of Bone Defects with Vessel—attached Periosteum and Homogeneous Decalcified Bone

带血管的骨膜及同种脱钙骨同时移植治疗大段骨缺损,具有骨缺损处愈合快,新生骨塑形优良,对肢体早期功能恢复起到较重要的作用。本文重点介绍其实验方法,X线片、光学及电子显微镜的超微结构观察,其生长愈合与骨折愈合机制是一致的,即按膜内成骨及软骨内成骨。带血管的骨膜及同种脱钙骨这二种组织内的骨膜细胞,在愈合过程中起着很重要的作用。

Using vessel—attached periosteum and homogenous decalcified bone to treat bone defects have beneficial effects in promoting healing of bone defects, forming neo—bone, and recovering the early function of limbs. The experimental method, disclosure of x—ray films, ultra structure changes under electron microscopy were presented. The results showed that with this way the mechanism of action of its promoting healing of bone defects was similar to that of healing of fractures, i. e. by intramembrane and intracatilage ossifications. The periosteal cells play a main role in the healing of the bone defect.
