Diagnostic value of MSCT in tibial plateau fracture with meniscus injury before operation
Objective To evaluate the diagnostic value of preoperative multi-slice computed tomography(MSCT)in tibial plateau fracture with meniscus injury.Methods The clinical data of 83 patients admitted to Liaocheng Second People's Hospital from January 2017 to December 2022 who were proposed to be treated with internal fixation of tibial plateau fractures were reviewed.All patients un-derwent preoperative MSCT and were divided into meniscus injury group and no meniscus injury group based on the gold standard of whether meniscal injury occurred as seen arthroscopically immediately after intraoperative fracture reduction and internal fixation.Baseline data and MSCT parameters were compared between the two groups.Subject work characteristic curve(ROC curve)was plotted to analyse the diagnostic value of MSCT parameters in complex tibial plateau fracture with meniscus injury.Results Meniscus injury occurred in 39(46.99%)cases of 83 patients with tibial plateau fractures,and the incidence of meniscus injury in type Ⅳ was 18.75%(3/16),which was lower than that in type Ⅱ(59.52%(25/42)(P<0.05).The percentage of Schatzker type Ⅱ was higher in the meniscus injury group than that in the no meniscus injury group,and the percentage of Schatzker type Ⅳ,the distance from the fracture tangent line to the lowest point of collapse,the distance from the lateral condyle tangent line to the distal end of the fracture block,and the rela-tive area of collapse detected by preoperative MSCT were higher than those in the no meniscus injury group(P<0.05).ROC curve analy-sis showed that the area under ROC curve(AUC)(95%CI)for fracture tangent line to nadir of collapse distance,lateral condyle tangent line to distal fracture block distance,and relative area of collapse alone and in combination for diagnosing meniscal injury of tibial pla-teau fractures was 0.64(0.56,0.72),0.70(0.62,0.78),0.76(0.67,0.83),and 0.89(0.83,0.94),with the diagnostic value of the combined application being higher than that single application(P<0.05).Conclusion Preoperative MSCT measurements of the lateral condyle tangential line to the distal end of the fracture block and the relative area of collapse are valuable for the diagnosis of meniscus injury.
