| 摘 要： | 目的研究髋臼后柱拉力螺钉内固定螺钉的最佳进钉点、方向和长度。方法取12个骨盆标本,其中男7个,女5个。於双侧髋臼中部垂直于前后柱表面截骨,逆行法沿后柱中心打入一克氏针,其从髂窝的穿出点为P点,作参考线AB,其中A为骶髂关节最前缘,B为髂前下棘基底下缘,由P点向AB作垂线,与AB相交于D点,然后测量以下数值:1.测量AB、AD、PD的距离;2.测量仰卧位时后柱克氏针与水平面的夹角α,与矢状面的夹角β;3.测量髋臼后柱截面的半径;4.测量后柱克氏针在骨皮质内的长度。结果PD是AB的中垂线。PD的距离男性为1.62±0.23cm,女性为1.51±0.10cm;夹角α男性为24.3±2.0°,女性为24.0±1.3°;夹角β男性为25.9±3.1°,女性为14.7±2.0°;后柱截面半径男性为10.18±1.24mm,女性为8.57±0.82mm;后柱克氏针长度男性为11.6±0.8cm,女性为10.2±0.5cm。结论髋臼后柱拉力螺钉内固定是可行的。

| Abstract: | Objective To study the best entry points,direction and length of screw in acetabular posterior column lag screw internal fixation. Methods Twelve pelves including seven male and five female pelves for the study.All specimens were sectioned across the middle of the acetabulum perpendicularly to the anterior and posterior surface of the anterior column.A Kirschner pin was forced retrogradely through the center of the posterior column.The projection point of the pin on the inner surface of the iliac bone was n... |
