Objective To evaluate the clinical curative effect of the treatment of intertrochanteric fractures with internal fixation by DHS.

目的 评价动力加压髋螺钉内固定治疗股骨粗隆间骨折的临床疗效。

Objective To study the results of intertrochanteric fractures treated with internal fixation of dynamic hip screw.

目的 探讨动力加压髋螺钉内固定治疗股骨转子间骨折的效果。

Objective: Intertrochanteric fractures occur in approximately 50 percent of all hip fractures.

目的：股骨转子间骨折约占所有髋部骨折的50％。

Thus, we cannot make a definitive evidence-based judgment across all age groups and all circumstances as to the best treatment of displaced intracapsular hip fractures.

因此， 基于循证医学，我们并不能得出在所有年龄组和所有条件下，移位的关节囊内髋部骨折最佳的治疗方法。

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。

No color signal of blood flow was demonstrated in 90.5%(19/21) of the entrapped labral plicaes.

结论髋臼内下缘的滑膜唇皱襞是LPEH发病的解剖学基础。

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。

After 1 year closed reduction treatment, the crest-time of lesional acetabular development is during the 1 to 3 months and 10 to 12 months.

闭合复位治疗 DDH 1年期间患侧髋臼的发育高峰期在复位后1～3月和10～12月。

After 1 year closed reduction treatment, rate of lesional acetabular development is obviously faster than rate of normal side physiological development.

闭合复位治疗 DDH 1年期间患侧髋臼发育速度明显快于健侧生理发育速度。
