| Abstract: | Morphometric study of T9-L5 pedicle was made on 15 cadavers with direct measurement and on radiographs. It includes four parts:height of pedicle,width of pedicle,length from posterior cortex of lamina to anterior cortex of vertebral body and angle between the axial line of pedicle and sagittal plane. Result indicates that: surgeons must choose suitable screws,site the starting points precisely,take care of the direction and depth of screws when they use pedicle screw fixation. |
