【摘要】：背景:研究报道股骨头前外侧柱的完整性和稳定性与股骨头坏死预后和保髋疗效呈正相关,中日友好医院分型强调前外侧柱的存留对维持股骨头不塌陷极其重要,目前此分型的三维数字化模型建立研究不多。目的:探讨基于中日友好医院分型的股骨头坏死高度仿真三维模型的获取方法。方法:基于正常股骨头患者的CT图像和股骨头坏死患者的MRI图像,采用三维重建技术对正常股骨头及坏死股骨头逆向重建。选择1名健康成年男性志愿者获取CT图像,并选择L1、L2、L3三型的右侧股骨头坏死患者各1例获取MRI图像,采用Mimics 15.0、Geomagic Studio 13、Geomagic Design X、Solidworks 2014、Abauqus6.14软件基于CT和MRI图像建立三维实体模型。结果与结论:建立了基于中日友好医院分型中L型的股骨头坏死高度仿真三维模型,包括髂骨和股骨近端的皮质骨和松质骨、关节软骨、股骨头坏死区、肌肉、关节囊及韧带等部分,可很好重建L型股骨头坏死的结构,可为治疗L型股骨头坏死提供虚拟手术方案,分析应用不同手术方案的生物力学比较,进而选择合适手术措施及方案,提高保髋的成功率。该高度仿真模型的建立,为生物力学分析和手术模拟提供了理想的研究基础。
[Abstract]:Background: it is reported that the integrity and stability of anterolateral column of femoral head are positively correlated with the prognosis of femoral head necrosis and the curative effect of hip preservation.At present, there are few researches on the establishment of three-dimensional digital model of this classification.Objective: to study the method of obtaining three-dimensional simulation model of femoral head necrosis based on the classification of Sino-Japanese friendly hospital.Methods: based on CT images of normal femoral head patients and MRI images of patients with avascular necrosis of femoral head, three dimensional reconstruction technique was used to reconstruct normal femoral head and necrotic femoral head.Ct images were obtained from a healthy adult male volunteer, and MRI images were obtained from 1 patient with right femoral head necrosis of L1T / L2OL3 type. The 3D solid model was established by Mimics 15.0 Studio Geomagic Studio 13 Geomagic Design XSolidworks 2014 (Abauqus 6.14) based on CT and MRI images.Results and conclusion: a highly simulated 3D model of femoral head necrosis based on L-type in Sino-Japanese Friendship Hospital was established, including cortical and cancellous bone of iliac bone and proximal femur, articular cartilage, necrotic zone of femoral head, muscle.The articular capsule and ligaments can reconstruct the structure of L-type femoral head necrosis, provide virtual surgical scheme for the treatment of L-type femoral head necrosis, and analyze the biomechanical comparison of different surgical schemes.Then appropriate operative measures and schemes were selected to improve the success rate of hip preservation.The establishment of the height simulation model provides an ideal basis for biomechanical analysis and surgical simulation.
