The major etiology of cubital tunnel syndrome is chronic injury with sustained compression of ulnar nerve around elbow joint.

结论］肘部的创伤及慢性劳损可以导致肘管弓状韧带出现肥厚增生，引起尺神经卡压磨损，这是肘管综合征最常见的病因；其他病因还包括慢性骨关节炎，占位病变和先天异常；尺神经可被机械性卡压和磨损，出现慢性缺血缺氧，导致肘管综合征的发生；详细的体格检查和术前的肌电图检查是诊断肘管综合征的主要手段，在诊断时应注意该病与其他部位迟发性尺神经麻痹的鉴别。

Abstract］ objective to explore the accuracy and safety of safety drillprepared for cervical pedicle screw trajectory.methods fourteen adult cadaver specimens of cervical spine（c3～c7）with intact structures including ligaments and perivertebral muscles were reserved and used.according to the radiographic measurements,safety drill was inserted into cervical pedicle individually.the evaluation of the drill's trajectory was carried out by ct scan and three-dimension reconstruction and autopsy.results one hundred and forty drill's trajectories were made.9 holes failed with a perforation rate of 6.4%.conclusion the safety drill prepared for cervical pedicle screw hole is safe and effective and can be applied and popularized clinically.

目的 探索安全钻头应用于颈椎弓根螺钉孔道钻探的安全性与准确性。方法随机取14具福尔马林浸泡的成人颈椎标本（c3～c7），保留完整的脊柱三柱结构及相关的韧带和椎旁肌，根据影像学测量的进钉点和进钉方向，模拟颈椎后路手术过程。选用安全钻头，进行实际的颈椎弓根螺钉孔道的钻探，将孔道行ct扫描，并斜位三维重建孔道形态，并以肉眼直视观察结果为金标准，评价孔道钻探的成败。结果钻探孔道准确率89.3%（125/140），穿孔率6.4%（9/140）。结论安全钻头应用于颈椎弓根螺钉孔道钻探的安全性与准确性均较高，可以在临床上推广使用。

objective to investigate the effect of radiography and method of operation on the surgical indication as well as the operation treatment of lumbar disc herniation and lumbar canal stenosis.methods the data of 300 cases with lumbar disc herniation and lumbar canal stenosis were reviewed from jan 1999 to dec 2004.all cases were treated by the method of minimal invasive open operation.the nucleus was resected through an 3.5～4.5cm in length.the sacrospinalis muscle between laminae was stripped partly and the part of upper lamina and the part of medial facet was resected.

目的 探讨影像学检查和手术方法对腰椎间盘突出症和椎管狭窄症手术方式和适应证的影响。方法自1999年1月～2004年12月，为300例腰椎间盘突出症和椎管狭窄症患者实施微创开放式手术，做3.5～4.5cm长的皮肤切口，剥离椎间的部分骶棘肌，咬除部分椎板上缘及小关节内侧缘后，摘除髓核，并根据需要做半椎板或全椎板手术或扩大神经根管和切除肥厚的黄韧带及神经管内的骨性增生。

The transversus abdominus is the deepest of the abdominal muscles and is responsible for supporting the lumbar spine and pelvic area at a time when ligaments are lax due to the natural hormone relaxin excreted by the body during the pregnancy and nursing stages.

腹直肌腹最深的是腹部的肌肉，负责支援腰椎及骨盆位于韧带松弛的时候，由于自然分泌的荷尔蒙松弛身体在怀孕和哺乳期。

The net effects of intrinsic muscle loss include the disturbance of precision and fine motor coordination, diminished muscle volume, severe impairment of power pinch and grasp, and creation of posture deformity to the index, middle, ring, and little fingers. We describe a 29-year-old man suffering low median-nerve and ulnar-nerve palsy with claw hand deformity.

我们报告一位29岁男性汽车修护工人，因为先前的正中及尺神经受伤而造成正中及尺神经控制的肌肉麻痹，甚至产生爪形手变形，由於他需要改善手部抓握功能来进行他的日常工作，於是我们采取使用桡侧伸腕短肌肌腱合并使用伸趾肌腱韧带移植来重建手部的抓握功能，并矫正手指的变形。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
