摘　　要：目的分析儿童肱骨髁上骨折的多层螺旋CT后处理的诊断效果,为儿童肱骨髁上骨折的诊断提供参考。方法选取2021年1月—2022年12月滕州市中心人民医院收治的60例儿童肱骨髁上骨折患儿为研究对象,患儿均进行多层螺旋CT平扫和CT后处理,分析两种方法图像特点,并对比两种诊断效能。结果多层螺旋CT后处理技术的灵敏度、特异度、准确度为98.33%、98.33%及100.00%,均高于多层螺旋CT平扫的86.67%、83.33%及88.33%,差异均有统计学意义(χ^(2)=4.324、6.405、5.461,P<0.05)。多层螺旋CT平扫结果显示,肱骨髁上骨质连续性中断,断端对位欠佳患儿53例、占88.33%;断端可见游离小骨块患儿35例、占58.33%。多层螺旋CT后处理技术结果显示,骨折远端旋转约30°的患儿38例、占63.33%,骨折远端旋转10°~15°的患儿22例、占36.67%。结论运用多层螺旋CT后处理技术诊断儿童肱骨髁上骨折优势明显,可更加准确、多角度地显示肱骨髁上骨折情况,明显提高患儿骨折诊断的准确性,具有较高的临床应用价值。Objective To analyze the diagnostic effect of multi-slice spiral CT post-processing for supracondylar fractures of the humerus in children,and to povide reference for the diagnosis of supracondylar fracture of humerus in children.Methods Sixty children with supracondylar fractures of humerus admitted to Tengzhou Central People's Hospital from January 2021 to December 2022 were selected as the research subjects.All children underwent multi-slice spiral CT plain scan and CT post-processing.The image characteristics of two methods were analyzed,and diagnostic efficiency of the two methods were compared.Results The sensitivity,specificity and accuracy of the post-processing technology of multi-slice spiral CT were 98.33%,98.33%and 100.00%,which were higher than those of the plain scan of multi-slice spiral CT with 86.67%,83.33%and 88.33%,and the differences were statistically significant(χ^(2)=4.324、6.405、5.461,P<0.05).The results of multi-slice spiral CT plain scan showed that 53 cases,accounting for 88.33%,showed continuous interruption of the supracondylar bone of the humerus and poor alignment of the fracture ends;35 cases,accounting for 58.33%,showed free small bone fragments at the broken ends.The results of multi-slice spiral CT post-processing technology showed that 38 cases,accounting for 63.33%,had fractures with a distal rotation of about 30°,and 22 cases,accounting for 36.67%,had fractures with a distal rotation of 10°~15°.Conclusion The use of multi-slice spiral CT post-processing technology had a significant advantage in diagnosing supracondylar fractures of the humerus in children.It could more accurately and from multiple angles display the situation of supracondylar fractures of the humerus,significantly improve the diagnostic accuracy rate of fractures in children,which had higher clinical application value.
