Application Value of Spiral CT Image Features in Fracture Classification and Efficacy Evaluation of Patients with Ankle Fracture

目的:探讨螺旋CT影像特征在踝关节骨折患者骨折分型及疗效评估中的应用价值。方法:收集2017年10月-2019年10月笔者所在医院收治的356例踝关节骨折患者作为研究对象,所有患者手术前后均行CT和X线片检查,并行术前骨折分型,以术中探查结果作为诊断金标准,观察CT检查影像特征在术前骨折分型及手术疗效评估中的应用价值。结果:螺旋CT对踝关节骨折分型诊断准确率为98.03%,X线片对踝关节骨折分型诊断准确率为89.61%,螺旋CT对踝关节骨折分型诊断准确率高于X线片,差异有统计学意义(P<0.05)。螺旋CT对踝关节骨折术后解剖复位检出率为92.13%,对踝关节骨折内固定置入适宜检出率为93.26%;X线片对踝关节骨折术后解剖复位检出率为82.58%,对踝关节骨折内固定置入适宜检出率为81.46%;螺旋CT对踝关节骨折术后解剖复位和内固定置入适宜检出率均高于X线片,差异均有统计学意义(P<0.05)。结论:螺旋CT对踝关节骨折分型及术后复位、内固定置入质量评估的准确率较高,具有较高的诊断和疗效评估价值,可为踝关节骨折患者的诊治提供诊断依据。

Objective:To explore the application value of spiral CT image features in fracture classification and efficacy evaluation of patients with ankle fracture.Method:A total of 356 patients with ankle fracture admitted to the author’s hospital from October 2017 to October 2019 were collected as research objects.All patients underwent CT and X-ray examination before and after surgery,and preoperative fracture classification was conducted.Intraoperative exploration results were used as the gold standard for diagnosis.the application value of CT imaging features in preoperative fracture classification and surgical efficacy evaluation were observed.Result:The diagnostic accuracy of spiral CT in the classification of ankle fracture was 98.03%,and that of X-ray in the classification of ankle fracture was 89.61%.The diagnostic accuracy of spiral CT in the classification of ankle fracture was higher than that of X-ray,and the difference was statistically significant (P<0.05).The detection rate of anatomic reduction by spiral CT was 92.13%,and the internal fixation of ankle fracture by spiral CT was 93.26%.The detection rate of anatomic reduction by X-ray was 82.58%,and the internal fixation of ankle fracture by X-ray was 81.46%.The appropriate detection rate of spiral CT for anatomic reduction and internal fixation of ankle joint fracture were higher than those of X-ray,the differences were statistically significant (P<0.05).Conclusion:Spiral CT has a high accuracy rate for the classification of ankle fractures and the quality of postoperative reduction and internal fixation.It has a high diagnostic and therapeutic value,and can provide a diagnostic basis for the diagnosis and treatment of ankle fracture patients.
