摘要:
目的对比CT三维重建模型下模拟髋臼前柱2种经皮置钉方法的效果。方法选取55例正常成人骨盆CT资料构建三维模型，共110侧髋臼前柱，调整模型透明度使其类似常规X线片，分别用2种置钉方法进行置钉，A组利用出口闭孔位和入口髂骨位引导置钉，B组利用髋臼前柱轴位引导置钉，置钉完成后恢复图像为不透明状态，记录螺钉是否进入髋关节及与耻骨支的位置关系。结果55例110侧髋臼，4侧未能找到髋臼前柱轴位影像予以剔除，106侧髋臼前柱纳入研究。2组模型均无螺钉进入髋臼。A组螺钉置入优秀、良好、尚可率分别为59.4%、17.0%、23.6%，B组分别为59.4%、226%、179%，2组总体置钉质量差异无统计学意义(Z=-0.829，P=0.407)。A组女性骨盆置钉优秀、良好、尚可率分别为7.1%、21.4%、71.4%，B组分别为28.6%、21.4%、50.0%，B组置钉质量显著高于A组(Z=-3.000，P=0.003)。A组男性骨盆置钉优秀率78.2%，良好率15.4%，尚可率6.4%，B组分别为70.5%、23.1%、6.4%，2组差异无显著性(Z=-0.969，P=0.333)。结论髋臼前柱轴位可以作为引导置钉的一种手段，尤其适用于女性患者，对于男性患者，2种方法均可实现较好的置钉。
Abstract:
ObjectiveTo compare the effects of two percutaneous screw placement methods for anterior column of acetabulumon under CT threedimensional reconstruction model. MethodsA total of 55 cases of normal adult pelvic CT data were selected to built 3D model, achieving 110 acetabulum anterior columns. The model transparency were adjusted to be similar to the conventional X ray film. The data were copied into the two groups. In group A, export obturator and entry ilium were used to guide nailing. In group B, the axial position of the anterior acetabular column was used to guide nailing. After the screw placement, the image was restored to an opaque state, and the position relationship between the screw and the pubic branch was recorded.ResultsAxial images of anterior acetabular column were not found in 4 sides, and 106 sides were included in the study. No screw entered the acetabulum in both groups. Excellent, good and fair rate of screw placement were 59.4%, 17.0% and 23.6% in the group A and 594%, 22.6% and 17.9% in the group B, respectively. There was no significant difference in the quality of screw placement between the two groups (Z=-0.829, P=0.407). For female patients, excellent, good and fair rate of screw placement were 286%, 21.4% and 50.0% in the group B and 7.1%, 21.4% and 71.4% in the group A, respectively. The quality of screw placement in the group B was significantly higher than that in the group A (Z=-3.000, P=0.003). For male patients, excellent, good and fair rate of screw placement were 78.2%, 15.4% and 6.4% in the group A and 70.5%, 23.1% and 6.4% in the group B, respectively. There was no significant difference between the two groups (Z=-0.969, P=0.333).ConclusionsThe axial position of the anterior acetabular column can be used as a means of guiding screw placement, especially for female patients. And for male patients, the both methods can achieve good screw placement.
