置换

Although there is fair evidence that articial disc replacement is similarly effective compared to fusion for single level degenerative disc disease and that an interspinous spacer device is superior to nonsurgical therapy for 1- or 2-level spinal stenosis with symptoms relieved with forward exion, insufcient evidence exists to judge longterm benets or harms.

尽管已有相当的证据证明人工椎间盘置换治疗单节段脊柱退变疾病具有和融合手术类似的疗效，也有相当的证据证明棘突间支架治疗1～2个节段伴间歇性跛行的椎管狭窄的疗效优于非手术治疗，但以上都缺乏长期随访的证据。

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。

Recent research shows hip arthroscopy can provide early diagnosis and treatment hip unexplained pain, such as femoroacetabular impingement,labral tears, chondral lesions, furthmore hip arthroscopy shows good prospects in the treatment avascular necrosis of femoral head, synovial abnormalities, post hip arthroplasty discomfort.

研究表明，髋关节镜对于既往不明原因的髋痛如髋关节撞击征、髋臼盂唇、髋臼软骨损伤可以早期诊断和治疗。此外，髋关节镜在股骨头坏死、股骨头圆韧带损伤、髋关节置换后的应用也展现出极大的应用前景。

研究表明，镜关节镜对于既往不明原因的髋痛如髋关节撞击征、髋臼盂唇、髓臼软骨损伤可以早期诊断和治疗。此外，髋关节镜在股骨头坏死、股骨头圆韧带损伤、髋关节置换后的应用也展现出极大的应用前景。

The femoral head arthrop lasty group had the least operation injury but had relative higher reversion rate and worse joint function compared to the total hip joint rep lacement group.

全髋置换术卧床时间短，并发症和手术翻修率低，术后髋关节功能最好，但手术创伤较大，对患者身体一般状况要求较高。
