CT三维重建对小儿肱骨髁上粉碎性骨折及在切开复位克氏针内固定术中的应用价值

Application Value of CT Three-dimensional Reconstruction in the Supracondylar Comminuted Fracture of the Humerus of Children and in Kirschner Wirethe Internal Fixation of Open Reduction

目的分析CT三维重建对小儿肱骨髁上粉碎性骨折及在切开复位克氏针内固定术中的应用价值。方法回顾性分析本院2017年6月至2019年9月收治的60例肱骨髁上粉碎性骨折患儿的临床资料,观察CT平扫及增强扫描的特点,对比CT平扫及CT三维重建技术对小儿肱骨髁上粉碎性骨折的诊断准确性、敏感性和特异性。结果CT平扫对小儿肱骨髁上粉碎性骨折的诊断灵敏性、特异性和准确性分别为88.33%、85.00%、90.00%,CT三维重建技术对小儿肱骨髁上粉碎性骨折的诊断灵敏性、特异性和准确性分别为98.33%、98.33%、100.00%,CT三维重建技术对小儿肱骨髁上粉碎性骨折的诊断灵敏性、特异性和准确性高于CT平扫检查,两者比较差异具有统计学意义(P<0.05)。结论CT三维重建可有效显示肱骨髁上粉碎性骨折的影像学特点,具有较高的诊断准确率,为临床上治疗肱骨髁上粉碎性骨折和康复计划的制定提供可靠的信息,值得广泛应用推广。

Objective To analyze the application value of CT three-dimensional reconstruction in the supra condylar comminuted fractu re of the humerus of children and fixation with Kirschner wires and open reduction internal fixation.Methods The clinical data of 60 children with supra condylar comminuted fracture of the humerus admitted to our hospital from June 2017 to September 2019 were retrospectively analyzed.The clinical data of 60 children with supracondylar comminuted fractures of the humerus admitted to our hospital from June 2017 to September 2019 were retrospectively analyzed.To observe the characteristics of CT plain scan and enhanced scan.The diagnostic accuracy,sensitivity,and specificity of CT scan and CT three-dimensional reconstruction technique for supracondylar comminuted fractu re of the humerus of children were compared.Results The diagnostic sensitivity,specificity,and accuracy of CT plain scan for supracondylar comminuted fracture of the humerus of children were 88.33%,85.00%,and 90.00%,respectively.The diagnostic sensitivity,specificity,and accuracy of the CT three-dimensional reconstruction technique were 98.33%,98.33%,and 100.00%.The diagnostic sensitivity,specificity,and accuracy of CT three-dimensional reconstruction technique for supracondylar comminuted fracture of the humerus of children were higher than those of CT plain scan.The difference between them was statistically significant(P<0.05).Conclusion CT threedimensional reconstruction can effectively display the imaging features of comminuted fracture of the supracondylar comminuted fracture of the humerus and has high diagnostic accuracy.It provides relia ble information for the clinical treatment of supracondylar comminuted fractu re of the humerus and rehabilitation plans,and it is worthy of widespread application.
