摘要

目的

探究62排螺旋CT及其后处理技术对胫骨平台骨折（TPF）的诊断价值以及对治疗方案选择的影响。

方法

纳入2021年1月至2022年12月在我院进行诊治的173例TPF患者，以手术病理诊断为金标准，比较X射线及CT扫描检查的诊断准确率、分型诊断准确率及骨折端塌陷程度准确率。

结果

CT及其后处理技术较X射线能够更清晰地显示骨折线的走向、骨折碎片的移位方向及关节面的塌陷程度，171例患者术中所见骨折形态均与CT及其后处理图像一致。X射线对TPF诊断准确率为93.64%，低于CT及其后处理技术对TPF诊断准确率（98.84%），差异有统计学意义（

，P

=0.011）。X射线对骨折端塌陷程度评估总准确率显著低于CT三维重建（65.32%

vs.

90.75%；

=0.001）。CT不同重建模式对TPF Schatzker分型诊断总准确率差异有统计学意义（

=40.647，

0.001），其中容积再现诊断准确率最高（96.53%）。

结论

应用CT检查及其后处理技术可有效评估TPF、关节面塌陷、骨折分型，并为临床决策提供影像学参考。

Abstract

Objective

To investigate the diagnostic value of 62-slice spiral CT and its post-processing techniques for tibial plateau fracture （TPF） and its influence on treatment regimens selection.

Methods

A total of 173 TPF patients diagnosed and treated in our hospital from January 2021 to December 2022 were included， and the diagnostic accuracy， classification diagostic accuracy and fracture collapse degree accuracy of X-ray and CT scans were compared， with surgical and pathological diagnosis as the gold standard.

Results

CT and its post-processing technique can more clearly show the direction of fracture line， the displacement direction of fracture fragments and the collapse degree of articular surface than X-ray.The fracture morphology of 171 patients seen during the operation was consistent with CT and its post-processing images.The diagnostic accuracy of X-ray for TPF was 93.64%， which was lower than that of CT and its post-processing techniques （98.84%）， and the difference was statistically significant （

=6.474，

=0.011）.The overall accuracy of X-ray in evaluating the degree of fracture collapse was significantly lower than that of CT 3D reconstruction （65.32%

.90.75%；

=32.644，

0.001）.The total accuracy of CT and its post-processing techniques for TPF Schatzker classification （97.69%） was higher than that of X-ray （88.44%），and the difference was statistically significant （

=11.462，

=0.001）.Different CT reconstruction models had statistically significant difference on the total accuracy of TPF Schatzker classification diagnosis （

=40.647，

0.001），and the diagnosis accuracy of volume reconstruction was the highest （96.53%）.

Conclusion

The application of CT and its post-processing techniques can effectively evaluate TPF， articular surface collapse and fracture classification， and provide imaging reference for clinical decision-making.
