The model had good duplicability and stability through the method of establishing the animal model in which the simple operative method,small wound and convenient nurse was obtained so easilyis that the animal model was spread easily.The study of the change of short and long period was made to provide the experimental base and reason through the animal model.

结论通过自制冲击器冲击兔右侧髋臼软骨，模拟冲击伤机制，初步建立髋臼软骨冲击伤实验动物模型并量化冲击能，通过统计学分析，大体和组织病理学检查，并与国外动物模型相比，本模型重复性和稳定性好，术式操作简单，创伤小，护理方便，易于推广，为研究活体动物髋臼软骨冲击后的短期和长期变化提供实验基础和依据。

Ten adult mixed breed dogs without significant individual difference were made transverse fracture at bilateral iliopectineal crest 1.5cm above the dome of acetabulum, which were fixed with ATMF'S or steel plate respectively. The animals were sacrificed and specimens were procured at 2, 4, 6, 8 and 12 weeks after operation. Samples from the fracture gaps were investigated by histology of HE and Masson staining, image pattern analysis of new bone formation.

方法］ 选用10只成年杂种家犬，双侧髋臼臼顶上方1.5cm处横形截骨，分别采用ATMFS（骨盆髋臼三维记忆内固定系统）前柱固定器和5孔重建钢板内固定，于术后2、4、6、8、12周处死动物取材，行HE染色、Masson三色法染色组织学检查，图像分析新骨形成积分光密度值，研究不同应力作用模式下的骨盆骨折愈合情况。

探讨持续顺应生理力线的压应力对犬骨盆弓状线部骨折愈合的影响［方法］选用10只成年杂家犬，双侧髋臼臼顶上方1.5 cm处横形截骨，分别采用ATMFS(骨盆髋臼三维记忆内固定系统)柱固定器和5孔重建钢板内固定，于术后2、4、6、8、12周处死动物取材，行HE染色、Masson三色法染色组织学检查，图像分析新骨形成积分光密度值，研究不同应力作用模式下的骨盆骨折愈合情况。

The different features of the osteolysis were compared radiographically.

方法对8例髋臼松动患者通过术前X线的评估，比较骨水泥臼和非骨水泥臼骨溶解的不同特点。

The hip images made with MPR showed that the minimum thickness of the medial wall of acetabula ranged from 2.0 mm to 10.9 mm.

MPR 冠状面和轴面成像示髋臼内侧壁最薄处的厚度为2.0 ～ 10.9 mm.15 例单侧脱位患者患侧与健侧髋臼比较，髋臼开口相差2.7 ～ 19.1 mm，深度相差2.3 ～ 13.1 mm。

Methods Acetabular index,CE angle,acetabuar head index and acetabular depth were carefully measured on roentgenograms of 120 developmental dysplasia of the hip cases over 5 years post-operation and 120 normal children whose age were similar to sick children as control group during following-up.

方法对比120例术后5年以上的双髋X光片和随机选择的与随访时年龄相近的120例正常的双髋正位X光片，仔细测量髋臼指数、CE角、臼头指数和髋臼深度，对单侧者还进行双侧对比测量。

Methods The osteotomy was performed along margin of acetabulum with acetabular wholism rotary to improve acetabulum to cover head of femur.

沿髋臼缘截骨，通过髋臼的整体旋转来加大髋臼对股骨头的包容。

Failures of cementless cups include accelerated polyethylene wear, malfunction of the locking mechanism of the polyethylene liner in the metal-backed shell,59–62 and extensive periacetabular osteolysis.63 Screw holes in the shell enable debris to access the periacetabular cancellous bone, a further extension of the effective joint space.

非骨水泥型髋臼杯的失败原因包括聚乙烯磨损加速，金属杯中聚乙烯内衬锁定机制失效和广泛的髋臼周边骨溶解。金属杯中的螺钉孔为碎屑进入髋臼周围松质骨提供了通道和更广的有效关节容积。
