H&E staining analysis of coronal plane sections of the femoral head in the 3 groups with different magnifications: (A-C=normal group) trabeculae were dense, continuous and thick, and almost no empty lacunae or cases of osteocyte death were detected; (D-F=model group,G-I=normal saline group) osteocyte death on the trabeculae was shown, and the sections also displayed more empty lacunae than in the normal group and zoledronic acid-treated group; (J-L ​= ​zoledronic acid-treated group) osteonecrosis was less than in the model group and there were more empty lacunae than in the normal group.(NS ​= ​normal saline); (bar:10× ​= ​100 ​μm, 20× ​= ​100 ​μm, 40× ​= ​50 ​μm).
