An Analysis of Failure Factors and Its Measures in Treatment of Femoral Neck Fracture with Close Reduction and Compressed Cannulate Screw Fixation

AO螺钉经皮内固定治疗股骨颈骨折失败原因分析及对策

Reduction of the middle column with screw insertion along the direction of the Lisfranc ligament is the key to reestablishment of the stability of the tarsometatarsal joint complex.

中间柱复位并沿Lisfranc韧带方向插入螺钉内固定是重建跖跗关节复合体稳定性的关键。

[ Method] A total of 86 cases of non-Chance fractures were instrumented with pedicel screw system generally. The positive and negative threaded sleeve were installed and circumrotated to obtain the compressed posterior column and reduction, then the screw cap was installed.

[方法]对86例非Chance骨折常规置入椎弓根螺钉后，安装并旋转正反螺纹套筒，使后柱加压，促使骨折复位，复位后安装螺帽及横连杆。

Independently designed the organization, which use the direct current machine to make gear reduction, and with the screw rod and the nut organization, the electrical machinery the positive and negative circumvolved motion changes into the straight line translational motion of the control accelerator tension bar.

自行设计了利用直流电机带动齿轮减速机构并通过螺杆与螺母机构把电机的正负旋转运动转化为控制油门拉杆的直线位移运动的执行机构。

Methods After reduction, the fragment was fixed by absorbable screw and wire to form tension band for olecranon and medial malleolus fracture.

方法将尺骨鹰嘴或内踝骨折复位，以1枚可吸收螺钉将尺骨鹰嘴与尺骨干或内踝与胫骨固定，骨干与螺钉尾部以可吸收线作张力带固定。

Methods Open reduction and internal fixation of the medial, lateral and the posterior malleolar fracture were used. The separation of the tibiofibular joint was fixed with a long screw or a bolt to keep the stability of the ankle mortise.

方法手术复位，内固定外踝、内踝或后踝骨折，有胫腓关节分离者用长螺钉或骨栓固定，以维持踝穴的稳定。
