目的 评价X线平片与多层螺旋 CT(MSCT)对胫骨平台骨折影像学诊断中 的临床应用价值。方法 收集2016年5 月-2018年7月我院收治的胫骨平台骨折患 者67例的影像学资料。所选患者均进行X 线平片与MSCT扫描检查，比较两种检查 方法对胫骨平台骨折的显示情况及诊断 价值。结果 X线平片对胫骨平台骨折的 检出率为64.18%(43/67)，MSCT扫描对胫 骨平台骨折的检出率为97.01%(65/67)， MSCT扫描对胫骨平台骨折的检出率高于X 线平片的检出率，且差异有统计学意义 (χ2 =70.631，P<0.05)；胫骨平台骨折患 者在影像学上均出现膝关节外侧间隙的不 对称性增宽，髌上囊积液，胫骨平台塌陷 等典型症状，同时存在局部压痛以及胫骨 平台外软组织肿胀的现象。结论 MSCT较X 线平片对胫骨平台骨折的检出率更高，能 够作为X线检查的补充检查手段，从而为 临床提供更加有力的影像学资料，提高临 床对胫骨平台骨折的诊断准确性。

Objective To evaluate the clinical application value of X-ray plain film and multi-slice spiral CT (MSCT) in the imaging diagnosis of tibial plateau fracture. Methods The imaging data of 67 patients with tibial plateau fracture treated in our hospital from May 2016 to July 2018 were collected. All patients were examined by X-ray plain film and MSCT scan, and the diagnostic value of the two methods were compared. Results The detection rate of tibial plateau fracture was 64.18% (43/67), 97.01% (65/67) was detected by MSCT scanning, and the detection rate of tibial plateau fracture by MSCT scanning was higher than that by X-ray scanning, with statistically significant difference (χ2 =70.631, P<0.05). In all the patients with tibial plateau fracture, asymmetric widening of the lateral gap of the knee joint, suprapatellar sac effusion, tibial plateau collapse and other typical symptoms, as well as local tenderness and swelling of the soft tissue outside the tibial plateau could be seen. Conclusion MSCT has a higher detection rate of tibial plateau fracture than X-ray plain film, and can be used as a supplementary examination method, so as to provide more imaging data for clinical practice and improve the accuracy of clinical diagnosis of tibial plateau fracture.
