Study on diagnosis of multi-slice spiral CT post-processing for supracondylar fracture of humerus in children
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 postprocessing.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(x2=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.
