目的 比较X线片与CT三维重建影像描述桡骨远端关节内骨折特征的具体差异.方法 利用Paces系统和MIMICS软件分析比较16例桡骨远端关节内骨折的X线片和CT三维重建影像学的特征.结果 16例桡骨远端关节内骨折的5个影像学指标,即桡腕关节面塌陷距离、骨折块的个数和移位间隙、骨折是否累及乙状切迹和伸肌腱骨纤维管道,在X线片与CT三维重建影像上的测量结果有较大差异.结论 CT三维重建影像能清楚地显示桡骨远端关节内骨折的特征,对骨折分型和治疗方法的选择具有重要的指导意义.
目的 比較X線片與CT三維重建影像描述橈骨遠耑關節內骨摺特徵的具體差異.方法 利用Paces繫統和MIMICS軟件分析比較16例橈骨遠耑關節內骨摺的X線片和CT三維重建影像學的特徵.結果 16例橈骨遠耑關節內骨摺的5箇影像學指標,即橈腕關節麵塌陷距離、骨摺塊的箇數和移位間隙、骨摺是否纍及乙狀切跡和伸肌腱骨纖維管道,在X線片與CT三維重建影像上的測量結果有較大差異.結論 CT三維重建影像能清楚地顯示橈骨遠耑關節內骨摺的特徵,對骨摺分型和治療方法的選擇具有重要的指導意義.

Objective To compare the accuracy of plain X-my fdms and reconstructed 3D CT images in assessing characteristics of intra-articular distal radius fractures.Methods X-ray films and reconstructed 3D CT images of 16 cases of intra-articular distal radius fractures were retrospectively analyzed using Paces System and MIMICS software.The parameters that were evaluated included the ability to detect intra-articular step and gap,fracture displacements,the number of articular fragments,stretch of the fracture line to the sigmoid notch and the extensor tendon tunnel.Resuts The average value for intm-articular step and gap were (0.92 ±0.75) mm and (0.71 ± 0.87) mm,respectively,on posteroanterior and lateral radiographys.The average value for intra-articular step and gap were (2.58 ± 1.23) mm and (2.89 ± 1.13) mm,respectively,on coronal and sagittal 3D CT images (P ＜ 0.05).The average number of artic~ar fragments was (3.25 ± 1.18) detected by X-ray and (4.68 ±0.49) detected by 3D CT images (P ＜0.05).The fracture line was found stretched to the sigrnoid notch and the extensor tendon tunnel in 2 cases and 4 cases,respectively,on radiographs.On 3D CT images it was found to be present in 14 cases and 15 cases,respectively(P＜0.05).Conclusion Standard radiographs (anteroposterior and lateral views) are not sugicient to measure anterior displacement nor accurate enough to measure medial displacement of distal radius fractures.Three-dimensional computed tomography improves both the mhability and the accuracy of radiographic characterization of the intra-articular distal radius fracture and influences treatment decisions.
