摘要
目的:研究髋臼前柱拉力螺钉内固定技术中螺钉的最佳进钉点、方向和长度。方法:取成年男性半骨盆标本20个,制作髋臼前柱系列断面。测量进钉点与坐骨大切迹顶点之间的水平距离和垂直距离,测量螺钉长度,测量螺钉矢状面和冠状面的角度,将测量数据输入到SPSS10.0进行统计学分析。结果:单螺钉技术:OP和PQ的长度分别为(23.5±2.2)mm和(16.8±1.6)mm,螺钉长度为(84.9±4.7)mm。双螺钉技术:O1P1和P1Q的长度分别为(26.3±2.3)mm和(13.6±1.4)mm,内侧螺钉的长度为(69.8±4.1)mm;O2P2和P2Q的长度分别为(20.7±2.1)mm和(20.1±1.8)mm,外侧螺钉的长度(61.2±3.7)mm。α角为(123.4±4.1)°,β角(62.2±5.8)°。结论:髋臼前柱拉力螺钉技术具有创伤小、固定强度大等优点,在某些髋臼骨折中应用具有明显的优势。
Objective： To study the best entry points, direction and length of screw in acetabular anterior column lag screw technique. Methods：Twenty male cadaveric adult semipelvic specimens were selected to determine and make serial cross-sections of the acetabular anterior column. The horizontal and vertical distances from entry point to apex of greater sciatic notch, the length of the screw, the angle of the screw on sagittal and coronal plane were measured respectively, and then all data were put into SPSS 10.0 for statistical analyze. Results： Under single screw technique, the length of OF and PQ was about （23.5±2.2）mm and （ 16.8± 1.6）mm respectively, the length of lag screw （84.9±4.7）mm. Under double screw technique, the length of O1p1 and P 1Q was （26.3±2.3）mm and（ 13.6±1.4）mm respectively, the length of medial lag screw （69.8±4.1） mm, the length of O2P2 and P2Q （ 20.7±2.1 ）mm and（ 20.1 ± 1.8 ）mm, the length of lateral lag screw （ 61.2 ±3.7 ）mm. Angle α was （ 123.4±4.1 ）° and angle β （ 62.2±5.8 ）°. Conclusions： Acetabular anterior column lag screw technique has advantages such as low trauma, high strength of fixation, when being applied in some types of acetabular fractures.
