髋臼

The shortest time to operation was 8 months;the longest time was 56 months,averaging 24 months. The high risk factors of HJD included bad acetabular ecstrophy angle,and anteversion angle.The etiological factor and tendency of dislocation in operation are also risk factors.

结果：平均随访24个月(8~ 56个月)，分析其中期疗效，髋臼外翻角和前倾角的异常是造成人工全髋关节置换术后脱位的高危因素，术前病因、术中脱位倾向是危险因素。

A modular femoral neck system of hip prosthesis is one method that can be used to obtain ideal femoral neck anteversion, offset, leg length and alignment.

摘要 全人工髋关节股骨柄上，股骨颈与股骨柄之模组化设计有利於手术过程中提供医师在完成股骨柄元件植入后，还能对於股骨颈与髋臼元件之间对位的调整，只要搭配选取不同的股骨颈元件弯曲角度或长度便可有效地重建髋关节的力学环境。

Age、gender、dislocation level、h/b rate、the wide rate of femoral head and femoral neck anteversion exerted obviously influence on lesional AI and AI, age、dislocation level and FNA were positive correlation of AI and negative correlation of AI, the wide rate of femoral head and h/b rate were netative correlation of AI and positive correlation of AI, the acetabular development of female was faster than male.

年龄、性别、脱位程度、 h/b 比率、股骨头宽度比和复位前患侧 FNA 对 AI 、 AI有明显影响，年龄、脱位程度和复位前患侧 FNA 与 AI 成正相关、 AI成负相关，股骨头宽度比和 h/b 比率与 AI 成负相关、 AI成正相关，女性较男性髋臼发育快。

1 Age use jiaopidou, 1-3 age use plasticity aluminium plank The patient is older who has heavy pathological changes use the three unite operation, The Chinese medicine is used by interior and external , push to take and to do exercises , observe the structural variety of the hip by measuring the femoral neck angle of anteversion and the index acetabulum, CE angle, the femoral head overlay rate.

年龄大、病变重的患者可行三联术，并结合中药内服、外敷、推拿练功治疗；0～3岁通过功能评定，而3岁以上才采用测量治疗前后股骨颈前倾角的变化、髋臼指数的变化、 CE角的变化、股骨头覆盖率的变化及功能评定，从而观察髋关节功能及结构的变化。

These were ealuated forCobb angle, end ertebrae selection, Ferguson angle, apex of the cure, C7 balance, pelic obliquity, Risser sign,status of the triradiate cartilage, kyphosis Cobb angle, endplate selection for kyphosis, and kyphotic index.

分别从Cobb角，终椎的选择，Ferguson角，顶椎的选择， C7平衡，骨盆倾斜， Risser征，髋臼"Y"软骨的情况，脊柱后凸Cobb角，脊柱后凸的终板选择，脊柱后凸指数进行测量。

Constrained acetabular liners are a very powerful weapon in the armamentarium to treat THA instability.

限制性髋臼衬垫是非常强有力的治疗髋关节置换不稳的医疗器具。

Objective:To explore the treatment of obesity by laparoscopic gastric banding.

目的：探讨髋臼后壁骨折临床特点和手术治疗方法及疗效的关系。

Methods: We retrospectiely analyzed twenty-four hips in twenty patients who underwent a Bernese periacetabular osteotomy, which was done with a proximal femoral algus-producing osteotomy in thirteen hips, for the treatment of acetabular dysplasia associated with proximal femoral structural abnormalities.

我们回顾性分析20位患者中的24例髋关节，他们都进行过Bernese periacetabular截骨术，对于髋臼发育不良合并股骨近段的结构异常分别在13例髋关节完成了股骨近段外翻截骨成型术。

Conclusion］1? It showes a higher stress dodge in the calcar femorale after using various kinds of prosthesis implantation? After using CFR/PSF of lower elastic modulus as handle, the stress dodge rate is lower in femur, but the interface stress is higher, and this is the main factor and reason for the prosthesis loosening? 2? The stress force rule meets the design principle that the stress force decreases gradually in the bone interface from proximal to distal? The stress value in different combination of same prosthesis handle has no significant difference, that showes mechanical factor is not the main standard for selecting prosthesis combination?

［结论］ 1、各种假体植入后均在股骨距处形成较高的应力遮挡，而用弹性模量较低的CFR/PSF作为柄，其股骨相应区域的应力遮挡率较低，但股骨相应界面应力较大，而界面应力过大是产生假体微动主要因素。2、股骨界面从近端至远端呈逐渐增高趋势的应力规律符合该假体的设计原理；相同假体柄的不同组合其股骨和髋臼相应界面应力值无明显差别，实验表明力学因素并不是选择假体组合的主要标准。

Objective To study the measurement method and significance of acetabular index in different CT coronal section in children.

目的 探讨儿童不同冠状面水平髋臼指数的测量方法及意义。
