基于计算机辅助系统对三维CT重建成像的股骨转子间骨折分型的临床研究

Clinical Study on the Classification of Femoral Intertrochanteric Fractures Based on 3D CT Reconstruction Imaging Based on Computer-Aided System

目的探讨计算机辅助系统对三维CT重建成像的股骨转子间骨折分型的临床研究。方法选取2016年1月至2018年12月我院收治的股骨转子间骨折128例患者,以手术治疗结果为"金标准",术前均进行三维CT扫描并重建成像,然后采用计算机辅助系统分析骨折分型情况。结果计算机辅助系统联合医师共同诊断股骨转子间骨折分型符合率为99.22%;计算机辅助系统诊断股骨转子间骨折分型符合率为89.06%;医师诊断股骨转子间骨折分型符合率为97.66%;医师独立诊断,诊断符合率为97.66%,计算机辅助系统诊断符合率为89.06%,两者差异具有统计学意义(P<0.05);医师独立诊断,诊断符合率为97.66%,计算机辅助系统联合医师诊断符合率99.22%,两者差异无统计学意义(P>0.05)。结论基于计算机辅助系统对三维CT重建成像的股骨转子间骨折分型具有良好的鉴别效果,同时配合医生临床应用具有较高的准确率。

Objective To explore the clinical research of computer aided system in the classification of femoral intertrochanteric fractures with 3D CT reconstruction imaging.Methods A total of 128 patients with intertrochanteric fractures treated in our hospital from January 2016 to December 2018 were selected.The surgical treatment was used as the"gold standard".Three-dimensional CT scans and reconstruction imaging were performed before surgery,and the fractures were analyzed using a computer-assisted system.Typing situation.Results The computer-assisted system and physicians jointly diagnosed the femoral intertrochanteric fracture classification rate was 99.22%;The computer-assisted system diagnosed the femoral intertrochanteric fracture classification coincidence rate was 89.06%;The doctor diagnosed the femoral intertrochanteric fracture classification coincidence rate was 97.66%The coincidence rate of independent diagnosis and diagnosis of residents was 97.66%,and the coincidence rate of computer-assisted system diagnosis was 89.06%,the difference was statistically significant(P<0.05);The coincidence rate of independent diagnosis and diagnosis of residents was 97.66%,and the combination of computer-aided systems Physician diagnosis coincidence rate was 99.22%,and there was no significant difference between the two(P>0.05).Conclusion The computer-aided system based on 3D CT reconstruction imaging of femoral intertrochanteric fractures has a good identification effect,and has a high accuracy rate in conjunction with the clinical application of doctors.
