Results. Cement augmentation of pedicle screws resulted in significantly higher failure loads (54%) and failure strength (69%) for both shaped indentors when compared with uncemented pedicle screws.

结果：经骨水泥增强的椎弓根螺钉组比无骨水泥组在负荷失败率和强度失败率方面两种形状的压配中均有显著差异。

Methods: 7 calf lumbar spine specimens (T13~S2) were biomechanically tested under pure moment of 10Nm loading with Tenor pedicle screw system as the fixation device. Range of motion and intradiscal pressure were measured in all unfused segments and compared among the control group, the single-segment-fixed group (L45) and the double-segment-fixed group (L3~L5), and the correlation analysis and comparison between the increments of kinematic index and intradiscal pressure were performed.

取7具小牛腰段脊柱标本(T13~S2)，以Tenor椎弓根螺钉系统作为固定器械，在10Nm纯力矩加载下进行生物力学测定，测定各活动节段的运动范围和椎间盘内压，比较完整对照组、L45单间隙固定组和L3~L5双间隙固定组间上述指标的变化，并对运动学指标和椎间盘内压增量进行相关分析和比较。

Methods Seven calf lumar spine specimens(T13~S2) were biomechanically tested under pure moment of 10Nm loading with Tenor pedicle screw system as the fixation device. Range of motion and intradiscal pressure were measured in all unfused segments and compared among the control group, the single-segment-fixed group (L4/5) and the double-segment-fixed group (L3~L5), and the correlation analysis was performed.

取7具小牛腰段脊柱标本(T13-S2)，以Tenor椎弓根螺钉系统作为固定器械，在10Nm纯力矩加载下进行生物力学测定，测定各活动节段的运动范围和间盘内压，比较完整对照组、L4／5单节段固定组和L3～L5双节段固定组间上述指标的变化，并进行相关分析。

The tumor did not transfer to the kidney. Rejection reaction, infection, bone unconnect, bone unhealing, bone absorption, and screw loosening were not observed in allograft region or even all over the body.

所有患者未见肺部转移，异体骨植骨区及全身无排异反应，术后无感染、骨不连、不愈合、骨质明显吸收及钢板螺钉断裂松动等并发症。

The reasons of internal fixation failure were nonanatomically reduction of fractures, unrigid interal fixation , over early weight bearing and poor placement of lag screw.

内固定失败原因是术中骨折未解剖复位、内固定不坚强、过早完全负重以及拉力螺钉位置不良。

Michael 开始旋开马桶的螺钉， Sucre 用镜子给他望风。

5 Except as noted in 20.6, a screw-shell lampholder for an infrared lamp shall be of the unswitched, medium-base type, and used with a 300-W or smaller lamp.

20.5除了20.6中提及的，红外线灯的螺钉壳固定器用不变的中等型号，并配用 300-W或更小的灯。

None of fracture ununited, infection, redislocation, screw loosen, plate broken were found. Functions of the shoulder joint were excellent.

无钢板断裂、螺钉松动、感染及再脱位，无骨折不愈合病例，肩关节功能均恢复良好。

Abstract］ Goal: Canada bundles with the power hip bolt Ties upbelt treats II ～IV thighbone Rotor bone fracture, discusses its clinical practice effect.

目的：用动力型髋螺钉加捆绑带治疗Ⅱ～Ⅳ型股骨转子间骨折，探讨其临床应用效果。

power hip bolt Canada bundles Ties upbelt treats the II~IV thighbone ExtensionSub bone fracture, through bundles Ties upbelt fixed which is apart from to the small rotor and the thighbone, coordinates DHC to thighbone ExtensionSub bone fracture fixed, can form a stable portal frame construction, after restores in the thick prosperous area the side BoneNature the strut and the bone structure integrity, is advantageous after the coxa technique the function restoration

动力型髋螺钉加捆绑带治疗II～IV型股骨转子间骨折，通过捆绑带对小转子及股骨距的固定，配合DHC对股骨转子间骨折的固定，能形成一稳定的框架结构，恢复粗隆区内后侧的骨性支撑及骨结构的完整性，有利于髋关节的术后功能恢复
