髋

Keene and Parker37 conducted a prospective study of 531 patients who underwent hemiarthroplasty with either an anterior or a posterior approach.

Keene 和Parker对531例患者进行了一项前瞻性研究，他们以前入路或者后入路进以半髋置换治疗。

The stude announces that their changeable regular of the center of gravity level speed in supporting phase is falling in tne first cushioning phase. When their center of gravity's vertical lines pass their heels and their knee joints go on extended contraction ,their center of gravity level speed has extended .the reason is that their angles have passed the heels and their swinging legs' kenn joints have swinging the front of their bodies. Its power originates the swinging leg's forward active swinging and the decurtation contraction of hip joints 、ankles of the supporting legs.the swinging leg shows "the calf's active backward swinging"before its landing impact,the skill affects the loss of center of gravity level speed when the swinging leg lands.they enlarge their trunks' forward-landing impact phase ,it can decrease the center of gravity level speed's loss after landing and impel the center of gravity level speed to pass the supporting spot quickly.

两人缓冲阶段身体重心水平速度变化规律是在体前缓冲阶段呈下降趋势；当身体重心垂线超过脚后跟后，在膝关节继续缓冲做退让收缩的情况下身体重心水平速度开始加大，原因是踝关节在最大缓冲时身体重心已移过支撑面及摆动腿膝关节已做体前摆动，主要动力来源于摆动腿的积极前摆和支撑腿髋、踝关节的克制性收缩；在摆动腿下压着地前期是大腿积极下压小腿随大腿的积极下压顺势向前下滑摆，在摆动腿下压着地后期表现出"小腿积极回摆"技术，对减小着地时的水平速度损失、加大向前用力都有积极影响；适当加大摆动下压着地阶段躯干的前倾角度，有利于减少着地时相的速度损失和有利于身体重心较快的移过支撑点；缩小后蹬结束后的后伸动作幅度，有利于减小腾空时间。

Methods 80 osteoporosis patients were grouped in two. Group A-40 people, after taking "Leli" calcium one hour, were treated by PEMFs on L1-S1 and coxa one hour a day, 30 times in total during fifty days while went on healthy diet and the Kinesiatrics for six months. Group B-40 people were treated by "Leli" calcium one piece a day, 30 times in total, and the healthy diet and the Kinesiatrics for six months.

原发性骨质疏松症患者80例，随机分为A、B两组，A组40例在饮食调护和运动疗法基础上，每天在服用1粒"乐力"钙片1h后，L1-S1部及髋部接受"磁振热"机器治疗1h，共计30次，历时约50d，饮食调护和运动疗法持续6个月。B组40例每天服用1粒"乐力"钙片，共30天，同时进行饮食调护和运动疗法6个月。

All patients have received bone healing. 12 cases showed bone healing 18-month later after X-ray inspection, the nail has been taken out and no fracture recur. the hip, knee extension and ankle brace, plantar flexion functions are good and normal walking is possible.

未发现主钉弯曲、锁钉脱出及断钉病例，开始负重时间为8～12周，平均9.1周，全部病例均获得骨性愈合。12例术后18月X线复查示骨性愈合，已取钉，无再发骨折，髋、膝关节伸屈及踝关节背伸、跖屈功能均好，行走正常。

Objective The purpose of this study was to describe the MR appearance of the acetabular labrum by using non-trauma technology.

目的 研究髋臼唇无创伤性MR的检查方法和最佳扫描序列。

Western-Blot method was used to detect the COLlal and COL3al in the ligamentum teres at protein level.

方法］选取性别相同年龄相近的6对发育性髋脱位患者及正常儿配对比较。

Anteroposterior view of right hip shows loosening of acetabular prosthesis with peri-prosthetic lucency,thought initially to represent particle disease.

右髋关节前后位图像显示髋臼假体松动，假体周围透亮，最初认识是粒子病。

Results The hip department ache accounts for 63%, the lumbago accounts for 40%.

结果 髋部疼痛者占63%，腰痛者占40%。

The observation of macrography and histology (stained by HE, safarnin O and toluidine blue) were made for the experimental group which were killed postinjuriously at 6 hour,4 week and 24 week.

通过对兔髋臼软骨模型分别在伤后6小时、4周和24周MRI扫描后，立即分别给予收集标本行大体观察和组织病理学检查。

Steels operation could correct internal rotation deformity of the hip and preserve abduction function of gluteus medius and minimus.

认为必须严格选择病例，掌握手术要点，该术式既矫正了髋内旋畸形，又保持了臀中小肌外展功能，以此获得满意疗效。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
