1、硕士学位论文二、18例骨盆模拟置钉试验结果在18例人体骨盆标本试验中,克氏针首次穿出点准确定位为15例(83.33%);良好定位为3例(16.7%);失败0例。男、女可置入螺钉长度分别为(131.53+5.36)mill、(118.154-9.03)Im,且性别之间的差异有统计学意义(P2、钉优1例(5.6%),良8例子(44.4%),差9例(50%);前方区域植钉优18例(100%),后方区域植钉优5例(27.8%),良4例(22.2%),差9例(50%)四、骨盆标本模拟植钉验证导向装置.坐骨结节进针点植钉结果内侧点,外侧点,前方点中15例优,3例良好,与中-tl,点植入效果一致;后侧点植入中11例优,3例良,4例失败。五、人体标本模拟植钉结果每例骨盆术中只需透视2次,术后X光显示植入后克氏针位置都较理想。结论1、根据髋臼后柱逆行拉力螺钉置钉的解剖学参数得知:髂前上棘,髂后上棘骨性突出点连线中点与坐骨结节中心点连线植入螺钉固定后柱骨折是可行的。2、在导向装置.髂骨固定3、点验证中,髂前上棘,髂后上棘选择固定点稍偏内侧,中点稍偏髂前上棘侧也有较好的植入结果。在导向装置.坐骨结节进针点的验证中一般不要太偏后侧都有较好的植入效果,再者骨盆较大者植入效果更佳,从而再次验证了导向装置的实用性及安全性。3、该导向装置植钉成功率高,具有个体化应用的特点,该导向装置在辅助螺钉植入中的准确性保障下,可以植入更长的拉力螺钉,给予骨折固定更强的稳定性。关键词:mimics;三维重建;髋臼后柱;导向装置;经皮拉力螺钉V硕士学位论文Developmentandpreliminaryvalidationofnavigationalapparatusforpercutaneous4、retrogradelagscrewfixationofthefracturesintheposteriorcolumnofacetabulumPostgraduate:ZhangPi-junSuperviser:WangGangSuoervlser:ABSTRACTBackgroundAcetabularfracturesareusuallycausedbyviolence,andtheysimultaneouslybringaboutdysfunctionofthehips.Thencethekeypointsoftreatmentforacetabularfracturesar5、eanatomicreductionandrigidinternalfixation.Openingreductionandplatefixationissatisfyingforthetrentmentofthefracturesintheanteriorcolumnandposteriorcolumnofacetabulum,whilebecauseoftheacetabulumanatomylocationisdeeper,adjacenttotheanatomyoftherelationshipiscomplex,thetraditionaloperationmethodof6、incisionislengthandexposedwidely,amountofbleeding,postoperativeheterotopicossification,iatrogenicsciaticnerveinjury,morecomplicationssuchasavascularnecrosis,seriousinfluenceonjointfunctionrecovery.In1988,Reinertreportedithastheadvantagesoflessinjuryandpromotefracturehealingusedcancellousbonescr7、ewtofixthefractureofacetabulumcolumn,fromthenon,fractureofacetabulumfixedwithScrewsgetmoreandmorewidely.Theremore,somescholarsconfirmedthatthelogscrewhadmorestrengththanplateABSTRACTfixedintheeffectofbiomechanics.Nearly10years,per
