摘要
目的：为骶骨置入螺钉固定术提供解剖学基础。方法：在１８例（３６侧）成尸脊柱标本上，解剖观测骶骨置入螺钉入路的安全区、置钉点、角度和深距。并在尸体上摹拟了术式。结果：骶骨背面有２个置钉安全区域，腰５骶１关节囊下安全区左右径６．０±１．２ｍｍ，上下径８．６±１．４ｍｍ。外侧安全区左右径９．１±２．１ｍｍ，上下径９．７±２．３ｍｍ。螺钉向内偏斜１５．１°～２２．９°，向尾侧偏斜５８．４°～６４．４°，向头侧偏斜６７．８°±９．３°。置钉深距３８．２～４８．０ｍｍ。结论：本文为从骶骨背面安全区域置钉至骶１。
Abstract Objective:To provide anatomy basis for sacral screw fixation.Methods:The screw entry point,route,angle and depth for sacral screw were measured on 18 cases(36 sides) of adult cadaver specimens.The corresponding safe area was defined and mimic operation was conducted on these specimens.Results:There were two safe areas for screw insertion in the back of sacra.The safe area inferior to L 5 and S 1 articular capsula was 8.6±1.4 mm in long and 6.0±1.2 mm in width.The other area lateral to the side of the L 5 and S 1 articular capsula 9.1±2.1 mm wide and 9.7±2.3 mm long.The screw should slant medially 15.1°-22.9°,caudal 58.4°-64.4°,cephalic 67.8°±9.3°.The depth of screw insertion was 38.2-48.0 mm.Conclusions:The screw could be inserted to fix spine from the safe areas to sacral back to anterior cortex of the first sacral vertebrae or the fifth lumbar vertebra.
