CT三维重建对踝关节骨折分型及手术效果评估价值分析

Value of CT Three-dimensional Reconstruction in the Classification of Ankle Fracture and Evaluating of Surgical Effect

目的分析CT三维重建对踝关节骨折分型及手术效果评估价值。方法回顾分析本院2015年6月至2019年7月收治的85例踝关节骨折患者的临床资料。将DR及CT的诊断结果进行讨论和分析;根据Lauge-Hansen分型,对比经DR及CT检查三维重建对踝关节骨折分型的准确性。比较术后DR及CT三维重建对各分型解剖复位率和内固定适宜率。结果 CT三维重建诊断踝关节骨折分型的准确率显著高于DR的诊断准确率(P<0.05);术后CT三维重建与DR检查对SER型、PA型、PER型复位质量比较差异具有统计学意义(P<0.05);CT三维重建与DR检查对SER型,PER型内固定置入质量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踝关节骨折的影像学特点,对踝关节骨折分型及术后复位治疗、内固定置入质量评估的诊断准确性高,为临床上治疗踝关节骨折和康复计划的制定提供可靠的信息,具有较高的应用价值。

Objective To analyze the value of CT three-dimensional reconstruction in the classification of ankle fracture and evaluating of surgical effect.Methods The clinical data of 85 patients with ankle fractures admitted to our hospital from June 2015 to July 2019 were retrospectively analyzed.The diagnosis results of DR and CT were discussed and analyzed.According to the Lauge-Hansen classification,the accuracy of three-dimensional reconstruction of DR and CT for the ankle fracture was compared.The rate of anatomical reduction and proper rate of internal fixation of postoperative DR and CT threedimensional reconstruction for each classification were compared.Results The accuracy of CT three-dimensional reconstruction in the diagnosis of classification of ankle fracture was significantly higher than that of DR(P<0.05).The difference in reduction outcome in SER type,PA type and PER type between postoperative CT three-dimensional reconstruction and DR examination was statistically significant(P<0.05).The difference in implant quality of internal fixation in SER type,PER type between postoperative CT three-dimensional reconstruction and DR examination was statistically significant(P<0.05).Conclusion CT three-dimensional reconstruction can effectively show the imaging features of ankle fractures,and has high diagnostic accuracy for the classification of ankle fractures and evaluating of postoperative reduction and implant quality of internal fixation,and provides reliable information for the clinical treatment of ankle fractures and rehabilitation programs,and has high application value.
