脊柱侧凸的数字化三维重建及临床应用

目的:建立精确的脊柱侧凸病人的脊柱数字化模型,探讨其在临床诊断及治疗中的应用。方法:随机选择6例脊柱侧凸病例,进行脊柱CT连续断层扫描,扫描结果导入Mimics软件中进行三维重建。利用三维重建模型指导临床。结果:全部病例均进行脊柱数字化三维重建,得到病变脊柱的三维立体图像。可以方便地从任意角度和方向观察脊柱畸形情况,测量有关的数据;还可以在数字化模型上进行手术设计,模拟内固定器械植入操作等。术中发现数字化模型与脊柱实际畸形情况完全一致。所有病人均接受手术治疗,手术过程顺利,术后效果满意。结论:脊柱的数字化三维模型能够更直观、更准确地反映了脊柱病变的三维立体结构。对临床医生的诊断、手术计划、内固定选择等有较大帮助。

Digital three-dimensional reconstruction of scoliosis and its clinical applications

Objective: To develop an accurate digital spinal model of scoliosis and explore its clinical applications. Methods: Six patients with scoliosis were chosen randomly and accepted CT scanning of spine before operations. Three- dimensional digital reconstruction based on these cross-section images were made in Mimics software and used to instruct operation procedures. Results: All patients were taken CT scanning and made three-dimensional construction of spine. Using the digital models, we can analyze abnormal spines from any angles or any orientations, as well measure data, design operation or imitate the process of implanting the internal fixation devices. The model can represent spines very well. All 6 patients were undertaken operations successfully and effectively. Conclusions: The digital three-dimensional model of spine could reflect the detailed information of the abnormal spine exactly and directly, which is helpful for diagnosing, planning of operations and choosing internal fixation.
