【摘要】 目的:探讨踝关节骨折诊断使用多排螺旋CT重建技术的价值及影像学特征。方法:选择笔者所在医院2018年1月-2020年1月收治的52例踝关节骨折患者,患者术前、术后均进行X线片、多排螺旋CT重建技术检查,对比两种检查结果。结果:多排螺旋CT检查骨折分型情况Kappa值为0.95,X线片检查Kappa值为0.79。多排螺旋CT外旋型、旋后内收型、旋前外展型、旋前外旋型骨折复位检出率及总检出率均高于X线片检查,差异均有统计学意义(P<0.05)。踝关节骨折在CT中表现为骨皮质掀起,骨质中断。结论:踝关节骨折诊断使用多排螺旋CT重建技术的价值明显,通过立体成像可以明确骨折分型,帮助临床医生准确判断患者骨折情况,提高影像学诊断的效果。该方法价值显著,值得临床推广使用。

The Value and Imaging Characteristics of Multi-row Spiral CT Reconstruction Technique for Ankle Fracture Diagnosis/CHEN Deping. //Chinese and Foreign Medical Research, 2020, 18(26): -80
[Abstract] Objective: To explore the value and imaging characteristics of multi-row spiral CT reconstruction technique for the diagnosis of ankle fractures. Method: A total of 52 patients with ankle fractures admitted to our hospital from January 2018 to January 2020 were selected. The patients were examined by X-ray and multi-row spiral CT reconstruction techniques before and after surgery, and the results of the two tests were compared. Result: The Kappa value of fracture classification was 0.95 for multi-row spiral CT examination and 0.79 for X-ray examination. The detection rate and total detection rate of multi-row spiral CT with external rotation, posterior adduction, anterior abduction and anterior externalization were all higher than those of X-ray examination, the differences were statistically significant (P<0.05). CT scan of ankle fracture showed cortical lifts and bone disruption. Conclusion: The diagnosis of ankle fractures using multi-row spiral CT reconstruction technology has obvious value. Stereoscopic imaging can determine the fracture classification, help clinicians to accurately judge the fracture situation of patients, and improve the effect of imaging diagnosis. This method has significant value and is worthy of clinical promotion.

踝關节骨折是临床高发骨折疾病,是关节内骨折的首位[1]。踝关节骨折分型较多,既往临床采用X线摄片进行检查,虽然具有一定的效果,但容易出现误诊、漏诊。随着CT诊断技术的发展,多排螺旋CT重建技术逐渐应用于临床并取得较好的效果,具有分辨率高、多平面、多角度的特点,对于骨折病变显示更加清晰[2]。术前对踝关节骨折患者进行影像学诊断有利于了解骨折的具体情况,辅助临床手术方案的制定。本研究探讨踝关节骨折诊断使用多排螺旋CT重建技术的价值及影像学特征,具体如下。
