尸体解剖的

Methods A wet hip joint's sample from corpse was scaned by CT and all images of every cross-section hip joint's layer was obtained, and an hip joint's model was contructed with Unigraphics NX 2.0 and Solid Works 2006 SP 0.0 software. The models were assembled when simulated total hip arthroplasty after total hip joint prosthetic and ischiofemoral ligament model had been constructured. Analysis was done on von Mises stress distribution and amount of total hip component when simulated seated leg-crossing manuver. The bone and metal components were meshed as rigid bodies, composed of three-dimensional, all-quadrilateral rigid body elements, and hip joint capsule ligament was fully three-dimensional, hexahedral continuum elements representations. Results The current form of this ischiofemoral ligament's reconstruction finite element model provided for multi-body contact, large displacement interfacial sliding, large deformation capsule ligament representation, and clearly reflected the real ischiofemoral ligansent's anatomy and biomechanical behavior. The maximum on Mises stresses at the joint interface was more than that fur an otherwise identical hardware-only construct.

选择成人尸体髋关节行CT成像得到髋关节每层横截面图像，提取边界坐标，利用有限元分析软件Unigraphics NX 2.0和Solid-Works 2006 SP0.0构建出髋关节三维有限元模型及人工髋关节假体，并模拟全髋置换术进行装配，将坐股韧带按其术中重建位置进行构建骨骼与金属模型采用三维十节点四面体实体单元进行网格划分，关节囊六面体连接单元划分，模拟坐位腿交叉动作载荷获取假体撞击过程的角活动度和相应的von Mises应力分布情况结果所构建的多体连接、大界面划移、大变形的坐股韧带重建有限元模型，客观反映坐股韧带真实解剖形态及生物力学行为，增加坐股韧带重建的模型其关节面的最大主应力值大于仅有金属的模型。

To systematicallyinvestigate this landmark, we conducted a study in four phases:1 Two blindfolded examiners determined the distance betweenthe tuberosity's medial border and the clavicle's lateral endin 100 dried clavicles and then 2 performed subclavian veincannulation in 20 fresh human cadavers using the tuberosityand the suprasternal notch as landmarks. 3 Three-dimensionalreconstructions of the subclavian artery and vein and surroundingstructures were derived from computed tomography datasets of10 patients. The length of the path of a virtual subclavianvein cannulation with the deltoid tuberosity landmark was measuredbilaterally. 4 In a prospective, randomized trial, subclavianvein cannulation was performed in 60 patients with a standardapproach or with the deltoid tuberosity as landmark.

为系统地研究这个解剖标志，作者将本研究分为四个阶段：1 双盲检查100个干燥的锁骨测量其三角肌粗隆内侧缘至锁骨侧面末端的距离；2 在20具新鲜的尸体上以三角肌粗隆和胸骨上切迹为标志进行锁骨下静脉穿刺；3 利用 CT 所获取的数据资料对10个病人的锁骨下动脉和静脉以及周围结构进行三维重建，测量两侧以三角肌粗隆为标志的虚拟锁骨下静脉置管路径的长度；4 选择60例病人以标准路径或三角肌粗隆为标志进行锁骨下静脉穿刺的前瞻性随机试验研究。
