Methods. Cells obtained from cancellous bone of both vertebrallamina and iliac crest were cultured and proliferation was evaluated by direct cell counting and viability detected by Trypan blue.
方法：细胞分离培养于椎板和髂嵴的松质骨，镜下计数细胞数目和台盼蓝染色检测细胞活力。

Two common sources of graft are vertebrallamina and iliac crest, however, differences in proliferation and osteoblastic phenotype expression between cells from these sites have not been investigated.
On the basis of imaging characteristics the fracture of lamina of vertebral arch was divided into 5 types: vertical, transversal, "7" -graphemic or reverse "7" -graphemic, "s" and displaced.
