查询词典 pedicle

Each of eight adult fresh cadaver specimen of lumbarsacral segmcnts was analyzed in four states: intact, L5S1 ALIF, L5S1 ALIF fixed with pedicle screw or fixed with translaminar facets screw, test and compare its range of motion in flexion, extension, lateral bending and axial rotation.

方法］ 采用新鲜腰椎标本8具，分别于完整状态、L5S1，前路植以Cage、L5S1，前路Cage分别行椎弓根钉固定及经椎板关节突螺钉固定下，测定前屈、后伸、侧弯及扭转运动下运动范围并进行比较。

Imaging-based measurements of introversion angle, declination angle, entry point and distance of spinous process at the horizontal plane are important data for percutaneous vertebroplasty. According to pedicle shape features at different stages, included angle, puncture point, path and depth, the vertebroplasty could be performed accurately and safely with reduced damage. Moreover, reliable data are provided for the design of a three-dimensional puncture-oriented device.

提示基于影像学所测量的内倾角、下倾角度、进针点与棘突在水平面上的距离等数据是进行经皮穿刺椎体成形术操作时的重要依据，根据不同阶段椎弓根形态学特点、夹角及确定穿刺点、穿刺路径和穿刺深度可以准确、安全进行操作，减少了损伤，也为设计一种三维立体穿刺导向器提供了可靠数据。

M moments was loaded to simulate lumbar axial compression, anteflexion, extension, lateral bending and rotation. The stress of the pedicle screws was recorded.

m的力矩模拟腰椎前屈、后伸、侧屈和旋转等各种生理载荷，观察不同载荷下螺钉的应力分布。

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。

ObjectiveTo explore the application of the flap in front of the ear supported by superficial muscle aponeurosis system pedicle for the repair of soft tissue defects around the eye.

目的：探讨颞部及耳前表浅肌肉筋膜蒂皮瓣在眼周皮肤软组织缺损修复中的应用。

Methods. A 60-year-old man with athetoid cerebral palsy and a history of posterior occipitocerical fusion presented with quadriparesis. Salage surgery for cerical myelopathy and pseudarthrosis was performed with laminectomy and rearthrodesis using the pedicle screw system. An intraspinal cyst was identified as the main cause of the paraparesis.

一位60岁的手足徐动症样大脑麻痹患者，既往曾行后路枕颈融合术，临床表现为四肢轻瘫，影像学检查示脊髓型颈椎病和假关节形成，采用椎板切除和椎弓根钉系统关节成形术后，发现椎管内存在的囊肿是导致四肢轻瘫的主要原因。

It can be used as auxiliary surgical instruments on the operation of traditional pedicle screw fixation.

在体外实验中，预警螺锥在胸腰椎(T8~L5)椎弓根螺钉钉道准备过程中，具有良好的报警效应，可作为传统椎弓根系统手术中的辅助器械。

Morphology of PMMA around the screws was related to the viscosity of PMMA during injection. No PMMA was found in vertebral canal or surface of pedicle.

PMMA在螺钉周围的分布与其注入时的粘稠度有关，未见椎管内或椎弓根外有PMMA分布。

［Objective］ To explore the method and cure effect of internal fixation of intervetebral crasis of posterior pedicle on lumbar surge syndrome.

［目的］探讨后路椎弓根内固定椎间融合术治疗腰椎滑脱症的方法和疗效。

Conclusion］ It is a mature and effective method to treat lumbar surge syndrome with internal fixation of intervetebral bone planting and crasis of posterior pedicle.

结论］后路椎弓根内固定椎间植骨融合治疗腰椎滑脱症是一种成熟有效方法。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
