前屈的

The patients were treated with routine manipulation(group A,30 cases) and PMWL(group B,30 cases) respectively.The difference pain,function,range of active anteflexion,anteflexion strength and satisfaction degree of patient were analyzed according to UCLA scoring system after one period of treatment score.

MAIN OUTCOME MEASURES: Stress images and peak stress of pedicle screws under lumbar axial compression, anteflexion, extension, lateral bending and rotation.

主要观察指标：椎弓根螺钉在轴向压缩、前屈、后伸、侧屈和旋转等各种生理载荷下的应力云图和峰值。

The difference pain,function,range of active anteflexion,anteflexion strength and satisfaction degree of patient were analyzed according to UCLA scoring system after one period of treatment score.Results:The pain,function and satisfaction degree of patient after treatment got better than those before treatment in group A(P.05);the active range and anteflexion strength had no improvement.

分为2组，分别采用常规治疗和杠杆扳法治疗，每组30例，在治疗1个疗程(10次)后利用UCLA进行功能评分，比较两种治疗方法在疼痛、功能、主动前屈活动、前屈肌力及患者满意度方面的差异。

RESULTS:In vertebral pulp extirpation group, the stress was proved to be the highest at superior edge, posterior middle part, lower edge and anterior middle part of small joints under anteflexion, backward extension, compression, lateroflexion and revolving states, moreover, small joint stress in artificial lumbar intervertebral disk was higher than that in normal intervertebral disk, but obviously lower than that in vertebral pulp extirpation group;however, the small joint of the middle part of artificial lumbar intervertebral disk bore the highest stress under revolving states.

结果：髓核摘除组小关节的上边缘部、后中部、下边缘部和前中部在前屈、后伸、压缩、侧屈、旋转状态应力最大，人工腰椎间盘组的小关节的应力比正常椎间盘高，但明显小于髓核摘除组，但正中部在旋转状态下，人工腰椎间盘小关节的中心部位承受的应力最大。

Methods Seven cadaveric spinal specimens were measured of neutrol zoneand range of motionin 6 movements including anteflexion,retroflexion,left and right lateral flexion,left and right axial rotation.

测试前屈、后伸、左侧弯、右侧弯、左旋转、右旋转的中性区(neutral zone，NZ)和运动范围(range of motion，ROM)。程序：完整状态；②骨折后状态；③椎体成形后；④3000次循环疲劳后。结果骨折后中性区和运动范围均明显增大。椎体成形后屈伸、侧弯、旋转在NZ及ROM均明显减少。

Results The axial length of eyeball was gradually decreased during the adult years of life accompanying with the increases of corneal and lens refractive powers and a decrease of anterior chamber depth fur maintaining a emmetropia status, and the steepness and thickness of lens, shallowness of anterior chamber contributed to emmetropia by decreasing the refractive index of lens.

结果 随着年龄增大，眼轴逐渐变短，但同时伴有角膜、晶状体屈光力的增大及前房深度的变浅以维持正视状态，晶状体的增厚、曲率的变大及前房的变浅可能通过屈光指数的减小同样维持了正视状态。

The splenius capitis muscle was found to be significantly different for flexion, left anterolateral flexion, and left lateral flexion.

头颈夹肌在前屈、左前侧屈、左侧屈时具有显著的差异。

The parameter of mechanics was analyzed with the finite element system in three anteflexed levels:6°, 9° and 12°. Results The stress and displacement of the right side of lumbar disc were increased gradually during the manipulation.

结果 ①对于正常腰椎，椎间盘左侧后缘的应力随着腰椎前屈角度增大而增大，前屈角度的变化对位移的影响相对较小，椎间盘无明显向后突出。

In all flexion activities, symmetrical or asymmetrical sternocleidomastoids were the major flexor muscles, and they had to balance the mechanics of the neck as agonists, synergists, or antagonists.

在所有的前屈肌中，对称性的和不对称的胸锁乳突肌是主要的前屈肌，并且，他们在颈椎的运动中，承担着主动肌、平衡肌和拮抗肌的作用。

Results:The anterior bundle of the UCL starts from anterior inferior part of the medial condyle,and ends on the sublimis tubercle in front of the coronoid process of ulna,locating in the deep layer of the flexor carpal ulnar muscle.The distance between ulnar nerve and UCL is (0.9±0.1)cm in the center of cubital tunnel,and (0.6±0.3)cm in the distal foramen of cubital tunnel.The distance from the point of ulnar nerve entering the flexor carpi ulnar muscle to the medial epicondyle is (3.7±0.8)cm.The distance between the closest branch innervated flexor muscle of the median nerve and the approach is (1.6±0.5)cm at the level of medial epicondyle,and (0.9±0.4)cm at the level of ulnar tubercle.

结果：UCL前束起于肱骨内侧髁的前下方，止于尺骨冠突内侧的小结节，UCL前束位于尺侧腕屈肌肱头、尺头之间的深层；尺神经在肘管中部与尺侧副韧带前束的平均距离为(0.9±0.1)cm，在肘管的远侧出口，距尺侧副韧带的尺骨止点(0.6±0.3)cm；尺神经至尺侧腕屈肌尺头肌支的入肌点距肱骨内侧髁的距离为(3.7±0.8)cm；正中神经最靠近切口的分支距切口的距离，在肱骨内侧髁和尺骨结节水平分别为(1.6±0.5)cm和(0.9±0.4)cm。
