髋关节置换

The rate of excellent and good functional recovery of hip was 94.0%. Postoperative internal-fixation-related complications occurred in 31 cases, including hip varus in 14 cases who had posterior intertrochanteric fragments, delayed union of fracture in 12 cases who had fractured calcar and lesser trochanter and massive dissection of soft tissues, and cutting-out of lag screws in five cases, three of whom had to receive prosthetic replacement.

术后髋关节功能恢复良好率达94.0%。215例患者中31例出现内固定相关术后并发症，其中髋内翻14例，主要发生于股骨转子内后方存在明显骨折碎裂的患者；骨折延迟愈合12例，为骨折累及股骨距及小转子，术中做软组织广泛剥离、骨折复位固定的患者；内固定物股骨头颈内切割并螺钉穿入髋关节腔5例，其中3例再行人工关节置换，关节功能Harris评分为82分。

Because hip replacement purpose is to eliminate pain and restore the function of the hip joint, improve the quality of life of patients.

因为髋关节的置换目的就是为了消除疼痛，和恢复髋关节的功能，提高患者的生活质量。

MAIN OUTCOME MEASURES: The pre and postoperative Harris scores for the hip, range of motion, periprosthetic radiolucency, leg-length inequality and complications were recorded and compared.

主要观察指标：记录并比较两组置换前/置换后髋关节Harris评分，髋关节活动范围，X射线假体周围透亮带，双下肢不等长及置换后并发症等指标。

Results from the present study show that compared with collum femoris preserving and stemless hip prosthesis, resurfacing arthroplasty may be the more effective treatment for avascular necrosis of femoral head with less complications and lower rate of revision.

提示与保留股骨颈全髋置换及无柄关节置换相比，表面置换对于恢复患者髋关节功能有着明显的优势，并发症少，翻修率低，对于年轻患者是一个较好的选择。

Methods Thirty eight patients with loosening of hip prosthesis were divided into three group: total hip arthoplasty, double hip arthuplasty and integrated arthoplasty. The inflammative reaction was analyzed with light microscopic observation arrording to the half-ration standard of Joseph, and the content of TNF in samples of interface membranes was determined.

方法］根据假体的类型及假体中是否含有聚乙烯将38例人工髋关节翻修病例分为3组：全髋置换组、双动头组和一体式单动头组，对各组术中松动假体周围界膜组织进行光镜下炎性细胞计数的半定量分析和肿瘤坏死因子的测定，分析人工髋关节无菌性松动与聚乙烯微粒、细胞因子之间的相关关系。

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.
