rve the structure of trabecular bones at different level of BMD，and evaluate the trend direction of trabecular bones structure of femoral head.Methods Measure the E?modulus and BMD with DEXA of bones in femoral head，and universal compression machine respectively；measure the static bone histomorphometry parameters with computer?controlled image analysis system；test the correlation between BMD and E?modulus，BMD and static bone histomorphometry parameters statistically.Results BMD could reflect E?modulus and static bone histomorphometry parameters very well.Conclusion BMD can reflect E?modulus and static bone histomorphometry parameters very well，and can be used in prediction of collapse of femoral head after avascular necrosis. Key words：bone mineral density；elastic modulus；histomorphometry；avascular Necrosis of the femoral head 成人缺血性股骨头坏死(avascular necrosis of the femoral head，ANFH)是骨科常见疾病。股骨头坏死后塌陷是导致髋关节功能受限或丧失从而致残的主要原因［1］。如能早期预测股骨头坏死后塌陷并予以适当处理，则有可能预防股骨头塌陷的发生［2，3］。 本实验测量股骨头松质骨骨密度(bone m
