骨内膜

结论该接骨板不钻孔，不用螺钉，对髓内血管及骨内膜无损伤，固定可靠。

Conclusion EBFP has the advantages of fixation without the drilling holes , no screws are used , the fixation is firm giving no trauma of intramedullary blood vessels and endosteum .

结论关闭髓腔的骨质只能来自于骨内膜成骨。

The new bone that closed the marrow cavity could only be formed by the endosteum .

Mechanical-biological Factor Coupled Simulation for Osteoporotic Process of Cortical Bone Endosteal

对骨外膜与骨内膜的初始直径大小进行设置，最后结果表明在生长期内骨干骨外膜和骨内膜直径明显增大，表现出骨外膜向外扩展和骨内膜扩展后吸收。

For bone initial geometries , the periosteal and endosteal diameters are set , the results show that the periosteal and endosteal diameters can increased significantly after simulation , it is presented that periosteum expands outward and endosteal resorbs after expansion .

密质骨：OVX组胫骨中段（TX）骨量减少（P<0.05），骨内膜骨形成和骨吸收增加。

Bone mass of compact bone of TX decreased ( P < 0 . 05 ), and endosteal bone formation and bone resorption increased in the OVX group ;

与B组比较，C组大鼠胫骨上段的骨量增加（%Tb.Ar+79.8%，P<0.05），骨高转换率降低；胫骨中段皮质骨骨外膜的骨形成增加，骨内膜的骨吸收降低（P<0.05）。

Bone mass of PTM more improved ( % Tb . Ar + 79.8 % , P < 0.05 ) and higher bone turnover reduced in group C than in group B. Testosterone also could elevate periosteal formation and endosteal bone resorption .
