动关节

With the method of psycholosical measuring, the indexes about kinesthesia accuracy of more joints of continuous moving of upper limbs, sensibility of wrist joint, 2-point discrimination threshold of skin, muscle forcibly sense and shoot exactness were measured in the state of different degree of fatigue.

摘 要：采用心理测量方法，对运动员在安静、中度疲劳、重度疲劳三种状态时的上肢多关节联动动觉准确性、腕关节敏感度、肤觉两点阈、肌肉用力感、投篮命中率5项指标进行测试，结果表明：四项感觉指标和投篮准确性在中度疲劳状态时较安静状态和重度疲劳状态有所提高；不同指标的变化差异不同，投篮准确性、肤觉两点阈、腕关节敏感度的变化达到显著或非常显著水平；而肌肉用力感和上肢多关节联动动觉准确性的变化差异未达到显著性水平；在三个不同疲劳状况下肤觉两点阈、腕关节敏感度与投篮准确性的变化相一致。

Joint friction and micromotion should inevitably form the biofilm and debris around the prosthesis, which will provide a breeding ground for the propagation of pathogenic microorganisms. On the contrary, the destruction of bone around the joint caused by infection is one of the reasons of joint sinking.

在一定条件下，术后关节感染与假体松动又是相互促进的，关节的摩擦和微动，必然会在假体周围形成界膜和微粒，这就为病原微生物的繁殖提供了条件；反之，关节周围的感染所造成的骨破坏，也是关节松动下沉的一个原因。

Chapters 4, 5, and 6 that together describe a chronological adance in our understanding of such.

接着章节是关于关节润滑作用和当今影像技术在这独一无二的生物动关节性解剖系统的应用。

Abstract］ Objective To provide the experience on treatment with the internal fixation to the fractures combined with/without dislocation on peripheral amphiarthrodial joint.

目的 通过对微动关节周围骨折和合并关节脱位的内固定治疗后的疗效分析，进而为临床治疗提供经验。

Abstract］ objective to provide the experience on treatment with the internal fixation to the fractures combined with/without dislocation on peripheral amphiarthrodial joint.methods from january 2000 to january 2005,62 cases were follow-up visited and evaluated on imageology,imaging,joint function and complication,et al.results serveral problems were observed on these cases.first,when the internal fixation were pulled out,some of the patients were observed the disturbance,even loss on joint function,and their quality of life were limmited.second,some internal fixations had been broken before they were pull out.conclusion we should sufficiently allow for not only the stabilization and the union of the fracture,but also degrade the complication to minimum limit and maximally recover the joint function.

目的 通过对微动关节周围骨折和合并关节脱位的内固定治疗后的疗效分析，进而为临床治疗提供经验。方法对2000年1月～2005年1月期间62例患者进行随访，并从影像学及关节功能、并发症等方面进行评估。结果治疗该类创伤病例存在着以下几个问题：（1）部分患者的关节功能在内固定解除术后，存在着不同程度的功能障碍，甚至丧失而影响到患者的生活质量。（2）并发内固定断裂情况时有发生。结论治疗微动关节周围骨折尤其在合并有关节脱位时，应充分考虑到既要修复因创伤引起的骨折使其愈合并使该关节稳定，又应该最大限度地恢复关节功能，并将并发症降低到最小限度。

Numerical analysis methods for articular cartilage of biphasic porous medium model are very important for the research of articular cartilage as well as entire diarthrodial joints.

关节软骨两相多孔介质模型数值分析方法是研究关节软骨和整个动关节力学行为的重要手段。

Articular cartilage is a layer of low-friction, load-bearing soft hydrated tissue covering articulating bony ends in diarthrodial joint.

关节软骨是覆盖在动关节骨端表面的一层低摩擦、可承载负荷的水合软组织，其力学性能通过软骨细胞的新陈代谢来维持。

To investigate the the body shape strength and kinematics thateffects sprint expert performance 17 healthy male sprinters weremeasured using SongxiaM9000 high speed vidicon in the field; body shape of sprint athlete were tested by steel rule; Meanwhile shoulder were tested at 60, 240and360 deg/sec velocities ; lower limb were tested at 60, 240 deg/sec velocitues using Biodex-II tesing and rehabilitation system in the laboratory This research provide theoretical basement to scientifically make reasonable exercise prescription and perfect sprint theoryThe result show that (1) The results of correlation indicate that 100M performance related to the shoulder fast flexion torque and hip flexion/extension torque^ ankle fast dorsiflexion torque ;(2) The upper arm relaxing enclose and lower limbs length effect 100Mperformance;(3) The biggest shoulder extension joint, swing rage of shoulder and the biggest elbow joint extension effect 100M performance.
