The primary etiology of avascular necrosis of the femoral head (AVN) appears to be circulating microemboli that block the microcirculation of the femoral head.

主要病因股骨头缺血性坏死股骨头（结）似乎是微循环，阻止微循环的股骨头。

Hydroprednisone acetate was injected into the rabbits of the model group using intragluteal injection to produce necrosis models of bone cells of femoral head.

模型组采用臀肌注射醋酸氢化尼松(简称激素)建立股骨头骨细胞坏死模型。
