摘要:
目的：对脊柱侧弯患者全脊柱进行数字化信息提取，研究矫形角度与矫形力的关系，并基于CT断层扫描数据信息对患者侧弯脊柱进行三维重建，验证矫形方案的可靠性，从而为患者提供最优的个体化脊柱侧弯矫形方案。方法：根据患者CT断层扫描数据，在Matlab软件中对患者侧弯脊柱进行数字化建模，以力学原理推导矫形力与矫形角度的关系式，从而确定脊柱侧弯矫形方案。利用Mimics19.0、3-Matic等医学三维软件，对患者脊柱侧弯部分进行完整三维重建并在AnsysWorkbench中进行有限元仿真，验证矫形方案效果。结果：重建出的脊柱三维模型能够准确反映患者实际脊柱侧弯情况，Matlab软件计算得到的最优化矫形方案能够在有限元仿真中得到验证。结论：基于数字化三维重建的脊柱侧弯矫形能够针对患者个体情况提供最优化的矫形方案，辅助临床医生选择满足患者实际需求的治疗方案。
Abstract:
Abstract: Objective To study the relationship between orthopedic angle and orthopedic load after extracting the digital information from the entire spine of patients with scoliosis, and to perform three-dimensional reconstruction of the scoliosis spine based on the CT data for verifying the reliability of the correction scheme, thereby providing patients with the optimal individualized scoliosis correction scheme. Methods According to the CT data, the scoliosis spine was digitally modeled in MATLAB software, and the relationship between orthopedic angle and orthopedic load was derived based on the principles of mechanics, so as to determine the optimal scoliosis correction scheme. Mimics19.0, 3-Matic and other medical three-dimensional software were used to complete the three-dimensional reconstruction of the scoliosis, and the efficacy of the scoliosis correction scheme was verified using a finite element simulation based on AnsysWorkbench. Results The reconstructed three-dimensional model of the spine could accurately reflect the actual scoliosis, and the optimal correction scheme calculated by MATLAB software could be verified by finite element simulation. Conclusion Scoliosis correction based on digital three-dimensional reconstruction can provide the optimal scoliosis correction scheme for the patients individual situation, and assist the clinicians to choose a treatment plan that meets the actual needs of the patients.
