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。

Methods:Fifty adult cadaveric specimens(100 sides) fixed with formalin were dissected,analyzed,and the palmar neurovascular structures,the flexor retinaculum,and their distance to the distal wrist crease were measured.

在行腕管探查术及掌中间隙引流术时，尤其是在环指中轴线上进行的内窥镜腕管松解术时易损伤邻近腕横韧带的神经血管，如尺/正中神经交通支[1]，尺神经[2]和掌浅弓[3]。

Therefore, Dr. Ciechomska and her coinvestigators wanted to see if ultrasound would accurately identify the features of nerve compression in patients with CTS. They obtained ultrasound images of 126 wrists in 52 patients who had been diagnosed as having CTS by EMG. They also obtained ultrasound images of the wrists of 22 healthy people. They used the Aspen unit (Acuson, Aliso Viejo, California), which was equipped with a linear, wideband transducer at 6 to 11 MHz.

Ciechomska和她的研究同僚于是对超音波进行研究，确定超音波是否可以正确的侦测出腕隧道症候群患者受到压迫的神经；研究人员从52位患者处获取了126个手腕超音波造影，这些患者皆经肌电图证实患有腕隧道症候群；同时，研究人员也取得了22位健康者的腕部超音波造影以为对照；所使用的仪器为Aspen (Acuson公司，位于加州Aliso Viejo市)，配备一线性的宽频电能转换器，频率设定在6到11 MHz。

objectiveto explore the application of carpometacarpal superficial vein graft in the digital replantation.methodthirty cases hospitalized in our hospital from january 2004 to october 2008 were dealed with vessel defect in the digital replantation by carpometacarpal superficial vein graft.resultsthe replanted fingers all survived,the appearance and function were good.conclusionusing carpometacarpal superficial vein graft is a good way to deal with vessel defect in the digital replantation.

目的：探讨腕掌侧浅静脉移植在断指再植中的应用。方法：对30例患者采用腕掌侧浅静脉移植处理断指再植手术中的血管缺损。结果：再植手指均成活，外观和功能良好。结论：对于断指再植中血管缺损的处理采用腕掌侧浅静脉移植是一种很好的方法。

In this case, a 34 year-old female presented with a dorsal wrist mass. Axial T1 image reveals a smoothly marginated mass deep to the ECRL and ECRB tendons

在本例中，一个34岁的女性出现背侧的腕部肿块，轴外T1显示一个边缘光整的肿块，深入至桡侧腕长伸肌腱和桡侧腕短伸肌腱

This model may simulate the load transmission better and contact stress distribution of carpal tunnel and radiocarpal joint, as well as provide an operational plateform for further deeply studing on biomechanical behavior of carpal structure.

本模型可以较好地模拟腕管和桡腕关节载荷传递与接触应力的分布情况，为进一步探讨腕部结构的力学行为提供了一个可操作的平台。

ObjectiveThe objective of this study is to provide the basis for the clinical diagnosis of whether the dorsal radiocarpal ligament is injury and treatment by knowing its normal patterns in the MRI. The primary approaches are anatomizing the dorsal radiocarpal ligament, studying the best scan sequence, angle, scanning level of MRI, and measuring its length, width and thickness.

目的本实验通过对桡腕背侧韧带的解剖，研究桡腕背侧韧带MRI成像的最佳扫描序列、角度及扫描层面，并丈量其长度、宽度及厚度，了解其在MRI影像中的正常形态，为临床诊断桡腕背侧韧带有无损伤其及治疗提供依据。

Results The computational results of force and pressure transmission through normal carpus matched well with previous studies. The release of TCL resulted in radial and palmar displacement of the scaphoid, flexion and radial rotation of radiocarpal joint as well as a further radial deviation of the whole carpal tunnel.

结果 腕部载荷传递及关节接触应力分布情况与前人实验数据相当接近；腕横韧带的切除导致舟骨发生向桡侧和掌侧的偏移，以及掌向屈曲和向桡侧的转动，而整个腕管结构则产生更大的桡侧偏移。

Methods A 3-D finite element model of the wrist based on CT scan images was established. The load transmission of carpus and the distribution of contact stress on radiocarpal joint under axial compressive force on metacarpals as well as the effect of transverse carpal ligament release on the displacement of carpal bones were computed and analyzed.

通过CT扫描图像数据对腕部进行三维有限元建模，计算并分析掌骨受轴向压力作用下正常腕部载荷传递及接触应力的分布，以及腕横韧带切开前后腕骨运动的变化情况。

According to normal condition, injured condition, repaired condition, repaired plus fixed device, injured plus fixed device in turn, between the tendinous sheath of extensor hallucis longus and lister tubercular, with the velocity 10mm/min the load is applied on the specimen. The translation changes from 0cm to 2.5cm during the test.

SPSS13.0统计分析软件分析在相同的位移情况下(1.5cm、2.0cm、2.5cm)，比较腕掌侧关节囊韧带复合体在上述五种情况下的负荷差别，了解腕关节掌侧关节囊韧带复合体在正常、损伤、修复及外固定支架对腕背伸稳定性的重要作用。
