【摘要】：目的探讨3D数字骨科技术在髋臼骨折治疗中的应用价值及其疗效。方法回顾分析2009年1月~2013年12月采用3D数字骨科技术进行辅助治疗的50例髋臼骨折患者资料,术前行薄层CT扫描获取骨盆二维数据,导入Mimics软件重建三维模型,计算机辅助分析髋臼骨折情况并进行模拟复位,快速成型技术制出与实体1∶1大小的骨盆模型。根据模型对髋臼骨折做出明确的诊断、分型,指导手术治疗。结果术中所见骨折及移位情况与术前三维重建图像及快速成型模型非常相似,术前模拟缩短了手术时间,减少了术中出血量。所有患者随访6~24个月,骨折复位情况根据Matta影像学评分标准:解剖复位41例,复位满意9例;髋关节功能按照Harris评分标准,优32例,良12例,可6例,优良率88%。结论 CT扫描三维重建、计算机辅助分析和模拟骨折复位,快速成型技术能直观、精确地显示髋臼骨折的立体形态和各解剖结构的空间关系,对髋臼骨折的诊断、分型及治疗具有良好的指导作用。
[Abstract]:Objective to evaluate the value and effect of 3 D digital orthopedic technique in the treatment of acetabular fractures.Methods the data of 50 patients with acetabular fracture treated with 3D digital orthopedic technique from January 2009 to December 2013 were retrospectively analyzed. The two-dimensional data of pelvis were obtained by thin slice CT scan before operation, and the 3D model was reconstructed with Mimics software.Computer aided analysis of acetabular fracture and simulated reduction, rapid prototyping technique to produce a pelvis model with the size of 1:1.According to the model of acetabular fracture to make a clear diagnosis, classification, guiding surgical treatment.Results the intraoperative fracture and displacement were similar to those of 3D reconstruction and rapid prototyping. The preoperative simulation shortened the operation time and reduced the amount of intraoperative bleeding.All the patients were followed up for 6 ~ 24 months. According to Matta imaging score, 41 cases had anatomic reduction and 9 cases had satisfactory reduction. According to the Harris score, the hip joint function was excellent in 32 cases, good in 12 cases, fair in 6 cases. The excellent and good rate was 88%.Conclusion CT scan 3D reconstruction, computer aided analysis and simulated fracture reduction, rapid prototyping technique can visualize and accurately display the three-dimensional shape of acetabular fracture and the spatial relationship of each anatomical structure, and diagnose acetabular fracture.Classification and treatment have a good guiding role.
