旋转关节

Methods: The sign object was put at each acromial end and clavicle end of normal acromioclavicular joint. And then acromioclavicular joint was tested the locations in abducetion+superduct 、 endoduction 、 anteflexion 、 post-extention 、 external and interior rotation by using 3D- laser scanning camera .Computer calculate the rotation of the two sign objects in x 、 y 、 z axis(x delegate clavicle axis,y delegate coronal section ,z delegate sagittal axis).

通过在正常活体肩锁关节的锁骨端及肩峰端分别安装一个激光照相扫描仪的探测端子，3D-激光扫描相机扫描肩关节在做前屈+上举，后伸，外展，内收，外旋及内旋等不同位置下两端子的位置，通过计算机计算出两端子在X、Y、Z轴（X轴代表锁骨的长轴，Y轴为冠状面与X轴垂直轴，Z轴为矢状轴）上的旋转情况。

The electric shoulder exerciser was designed for the elderly to do passive shoulder exercises by electric rotary table.

电动肩关节练习器采用电动助力的旋转轮盘式设计，适用于老年患者做被动肩关节训练。

The front suture width of axis and atlas joints and the shift degree of dens were also measured.results: 13 cases with 19 bone broken points,the positions are at dens ,side plank of atlas,occipital,plank of axis,processus spinosus etc.23 cases with axis and atlas half dislocation.of which,16 cases were with pure dislocation,7 cases with rotating dislocation,11 cases were with swollen at the side of vertebra,2 cases with depressing of vertebral artery,5 cases with continued narrowing of vertebral canal.conclusions: ct has the advantage of quickness,safety and high density discerning,it can reveal details of acute axis and atlas damages,so it has great importance to treatment scheme making and to the prognosticate.

结果：13例共见19处骨折，部位分别为齿状突、寰椎侧块、枕骨、枢椎椎板、棘突等，寰枢关节脱位23例，其中单纯性脱位16例，旋转性半脱位7例，11例合并椎旁血肿，2例见椎动脉受压，5例继发性椎管狭窄。结论：ct具有快捷、安全、密度分辨率高等优点，可明确急性寰枢关节损伤细节，对制定治疗方案及估价预后具有重要作用。

However, for multistory and multibay frames in which there are a large number of members and joints, and which will, in general, involve translation as well as rotation of these joints, the effort required to solve the correspondingly large number of simultaneous equations is prohibitive.

然而，对于多层和框架的MultiBay，其中有一个成员和大量关节，并会在一般情况下，涉及翻译，以及这些关节旋转，这种努力要解决相应的方程组的大量过高。

Current application for hip arthroscopy include management of labral tears, osteoplasty for femoroacetabular impingement, thermal capsulorrhaphy and capsular plication for subtle rotational instability and capsular laxity, lateral impact injury and chondral lesions, osteochondritis dissecans, ligamentum teres injuries, internal and external snapping hip, removal of loose bodies, synovial biopsy, subtotal synovectomy, synovial chondromatosis, infection, and certain cases of mild to moderate osteoarthritis with associated mechanical symptoms.

目前髋关节镜主要应用于盂唇撕裂的处理、股骨髋臼的撞击症的骨成形、隐匿性髋关节旋转不稳的热关节囊紧缩或关节囊皱折术，治疗软骨损伤、剥脱性骨软骨炎、圆韧带损伤、内源性或外源性弹响髋，清除游离体、滑膜活检、滑膜次全切、滑膜软骨瘤病、感染和某些伴有机械症状的轻度至中度骨性关节炎。

Pivot joint A joint in which a bone rotates around another; ajoint permitting only rotating movement.

枢轴关节一根骨头得以绕着另一根转的关节；仅允许旋转运动的关节

There are more than two dozen reported cases of lumbar facet dislocation after rapid deceleration injuries (e.g., traffic accidents), most involving L5 S1.61,112 115 The mechanism of injury in these cases is purported to be a combination of hyperflexion, distraction, and rotation.61,112,116 In a posthumous study conducted in 31 lumbar spines of subjects who died of traumatic injuries,Twomey et al.117 found occult bony fractures in the superior articular process or subchondral bone plate in 35% of victims, and z-joint capsular and/or articular cartilage damage in 77% of cases.

多项研究报道了急性减速伤后发生腰椎小关节分离，多数发生于L5-S1，其机制可能为过度屈曲，分离和旋转。在一项对死亡病例的研究中，Twomey 等发现，31例因交通事故死亡的人中有35%的腰椎上关节突或软骨下骨性终板存在隐匿骨折，77%存在小关节囊和/或关节软骨损伤。

Isolated rotatory dislocation is very rare in adults.11–13 Few cases of AARFs have been reported in adults, perhaps because the cause may often be a severe trauma associated with lethal injuries.3,4,12,14 –19 The mechanisms underlying persistent displacement in traumatic AARF include infolding of the synovial folds into the C1–C2 joints, muscle spasm, subsequent ligamentous contracture, articular cartilage damage, or facet fracture.1,11

离体旋转脱位在成人也很少见[11-13]。关于成人AARF病例的报道甚少，可能与严重创伤通常与高致死性损害相关[3，4，12，14 –19]。创伤性AARF持续移位的主要原因包括滑膜襞内折入C1-C2关节、肌肉痉挛、继发韧带孪缩、关节软件损伤或关节突骨折[1，11]。

Radiologic studies conducted in LBP patients and asymptomatic controls have shown a positive correlation between sagittally oriented facet joints and degenerative spondylolisthesis.48,49 In these patients, recurrent rotational strains result in myriad changes to the discs and paired l-z joints, including loss of disc height, osteophyte formation, and degenerative hypertrophy of the facets.90,91

放射学研究表明，下腰痛患者及无症状的对照组中，小关节矢状面方向及退行性滑脱之间存在正相关。在这些患者中，反复的旋转性应力导致椎间盘和小关节的多种改变，包括椎间盘高度丢失，骨赘形成和退变性关节面增生等。

After discectomy, partial laminectomy and bilateral medial 1/3 facetectomy, the ROM of L4-L5 segment was significantly increased in flexion, extension, left and right lateral bendings as well as left and right axial rotations (relative ROM 1. 34, 1. 94, 1. 19, 1. 34, 2. 23, 1. 52 seperatively).

随着双侧小关节逐级切除，各组运动的运动范围明显呈逐渐增加趋势，双侧小关节内侧1/3切除和双侧小关节全切除状态之间在前屈、左右侧弯、左右轴向旋转运动方面有显著性差异。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
