摘要

本文对正常髋型患者的骨盆不同倾斜程度的交叉征(COS)进行了三维打印CT扫描的研究。方法回顾性分析8例正常骨盆三维重建的CT扫描结果，并对48张正常骨盆的顺序倾斜对假阳性COS的影响进行分析。结果倾斜改变时77%的AP片出现COS。尾骨尖端至耻骨联合的平均距离为32.06±10.99 mm。此外，所有倾斜6度及以上的x线片均出现COSs。结论骨盆轻微倾斜可导致AP平片假阳性交叉征象。

Evaluation of Crossover Sign in Pelvis Models Made with a Three-Dimensional Printer

Introduction Investigation of the crossover sign (COS) in different degrees of tilt in pelvises made by three-dimensional printing of CT scans among patients with normal hip versions was carried out. Methods Radiology CT scans of 8 normal pelvises reconstructed in 3D and the effect of sequential tilting on the presence of the false-positive COS in 48 radiographs were investigated. Results The COS was seen in 77% of the AP radiographs during tilt changes. The average distance between the tip of the coccyx and the symphysis pubis was 32.06 ± 10.99 mm. Also, COSs were present in all radiographs from 6 degrees tilt and above. Conclusion Minor tilting of the pelvis can result in a false-positive crossover sign on AP plain radiographs.
