螺旋CT重建技术在骨盆环骨折中的诊治价值

目的:探讨螺旋CT二维多平面重建(MPR)、三维重建(3D)对骨盆环骨折的诊断、分型及治疗的临床价值。方法:回顾性分析2004年4月至2009年4月收治的有完整的X线DR(digital radiography)片、螺旋CT片影像资料的57例骨盆环骨折患者,根据Tile分类,本组病例A型38例,B型12例,C型7例。对A型患者采取保守治疗,对B、C型患者全部采取手术治疗,根据骨折移位情况,采用开放复位内固定或经皮行骶髂关节空心螺钉内固定术。术后3d～27个月内进行随访,利用螺旋CT检查进行术后疗效评估,对其术前术后的DR片、螺旋CT的3D、MPR的重建图像进行对照分析。结果:57例骨盆环骨折患者中,5例骨盆后环骨折患者的X线DR片诊断为可疑骨折,9例骨盆后环骨折X线DR片漏诊,3例骨盆前环骨折患者的X线DR片诊断为可疑骨折,3例骨盆前环骨折患者的X线DR片漏诊,后经螺旋CT检查予以修正。术后影像学评价优15例,良3例,差1例;临床评价优16例,良3例。结论:螺旋CT的MPR、3D的重建图像对骨盆环骨折的诊断、分型及临床治疗评估具有重要的临床价值。

Study on the spiral CT reconstruction in the diagnosis and treatment of pelvic ring fractures

Objective:To investigate the clinical value of spiral CT with multi planar reconstruction(MPR) and three diamensions reconstruction(3D) in the diagnosis and treatment of pelvic ring fractures. Methods:Fifty seven patients with pelvic ring fractures were examined with digital radiography and spiral CT in our hospital from April 2004 to April 2009. According to Tile classification,there were thirty eight cases in type A,twelve in type B and seven in type C. Expectant treatment was used in type A,while surgery...
