双层螺旋CT三维重建诊断股骨头骨折及预后评估的价值

摘要

目的:评估双层螺旋CT(DSCT)多平面重建(MPR)及容积再现(VR)技术在股骨头骨折中的应用价值.方法:回顾性分析32例股骨头骨折的X线片和DSCT多平面重建及VR技术临床资料.结果:32例中单纯型股骨头骨折13例,X线片漏诊5例；股骨头骨折伴脱位15例,X线片漏诊2例(臼顶中心脱位).术后复查经MPR及VR技术发现固定螺钉断裂1例,骨折断端对位对线差5例.结论:DSCT三维重建MPR及VR技术在股骨头骨折诊断及预后评估中与普通X线检查相比有明显优势.%Objective To assess the value of double-spiral CT (DSCT) multi -planar reconstruction (MPR) and volume rendering (VR) technology in the application of femoral head fracture. Methods 32 cases of femoral head fracture X-ray films and DSCT multi-planar reconstruction (MPR) and the clinical data of VR technology were retrospectively analyzed. Results In the 32 cases, simple femoral head fracture was 13 cases, X-ray missed 5 cases; femoral head fracture with dislocation was 15 cases, X-ray missed 2 cases (central dislocation of the acetabular roof). After review by the MPR and VR technology, screw breakage was found in 1 case, fracture line on the position of the line difference in 5 cases. Conclusion DSCT three-dimensional reconstruction of MPR and VR technology in the diagnosis and prognosis of femoral head fractures in comparison with ordinary X -ray examination has an obvious advantage.
