文题释义:
股骨头坏死的中日友好医院分型:中日友好医院的李子荣教授等以股骨头三柱结构为基础,以坏死灶占据的三柱结构情况,并吸取了JIC法与Koo法的优点,选用MRI或CT扫描冠状位正中层面进行分型,分为:M型(内侧型)、C型(中央型)、L型(外侧型)三大型,其中L型分3个亚型:L1型(次外侧型)、L2型(极外侧型)、L3型(全头型)。
股骨头坏死三维模型的建立:利用CT和MRI影像资料,运用三维重建技术,建立基于中日友好医院分型的股骨头坏死髋关节三维立体模型,高度仿真模拟髋关节各种结构关系,为生物力学有限元分析及手术模拟提供基础。
 
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: Anterior and lateral columns of the femoral head integrity and stability have been reported to present a positive correlation with the prognosis of the osteonecrosis of the femoral head (ONFH) and efficacy of hip preserving. China-Japan Friendship Hospital Classification stressed that the retention of the anterior and lateral columns of the femoral head was of great importance to avoid the femoral head collapse, but there is little reported on its three-dimensional (3D) digital model.

OBJECTIVE: To explore the method of establishing highly-simulated 3D model of China-Japan Friendship Hospital Classification for ONFH.
METHODS: 3D reconstruction of normal and necrotic femoral head was established according to the CT and MRI of individuals with normal femoral head. A healthy adult male volunteer was selected and his CT image was collected; three adult male patients with types L1, L2 and L3 ONFH were selected, whose MRI images were obtained, respectively. 3D solid models were established based on CT and MRI data on Mimics 15.0, Geomagic Studio 13, Geomagic Design X, Solidworks2014 and Abauqus6.14 software.
RESULTS AND CONCLUSION: A highly-simulated 3D model of L type ONFH was established, including the cortical and cancellous bones of ilium and proximal femur, articular cartilage, necrotic articular cartilage, muscles, joint capsule and ligaments. It clearly showed the spatial structures of L type ONFH, by which different surgical programs could be compared in a virtual environment for selecting an appropriate treatment strategy to improve the success rate of hip preserving. The highly-simulated 3D model paves ways for surgical simulation and biomechanical analysis.
