pedicle screw

Posterior segmental pedicle screw instrumentation, with its more powerful corrective force oer hooks, could offer significant advantages.

There was no pedicle screw loosening or broken and relieved vertebrae in this series.

Summary of Background Data. Pullout strength of a pedicle screw increases as the diameter of the screw gets larger.

Conclusion The operation of posterior pedicle screw and lumbar fusion is an effective way of treating severe lumbar instability. . .

Segmental pedicle screw instrumentation and intraoperative neurophysiologic monitoring was used in all patients.

Objective: It summarized operative coordination measures of patients undergoing thoracolumbar vertebral pedicle screw internal fixation.

Objective. To determine risk factors and outcomes for acute fractures at the proximal aspect of long pedicle screw constructs.

However, multiple reports confirm that pedicle screw placement in the thoracic spine can be performed with both accuracy and safety.

Objective. To determine the accuracy of pedicle screw hole placements before screw implantation in the lumbar spine.

RESULTS AND CONCLUSION: The focus on increasing stability of pedicle screw is to increase screw withdrawal resistance.

Objectives To analyze the reason and strategy for failure of posterior pedicle screw internal fixation on serious thoracolumbar fractures.

Objective To investigate the therapeutic results of the posterior pelvic ring with pedicle screw fixation system.

The most recent instrumentation innovation for the treatment of adolescent idiopathic scoliosis (AIS) is pedicle screw.

Study Design. Case report of pedicle screw fixation in an infant with non accidental spine trauma.

Objective To discuss the reasons and preventive measures for complications of thoracolumbar pedicle screw fixation.

Summary of Background Data. Safety concerns have driven specific interests in the accuracy and precision of pedicle screw placement.

Conclusion: The process for impacting the pedicle screw by synthetic location is a good moted for less complications and better effect.

Results. Ultrasonographic images of pedicle screw holes in postmortem human spine specimen were correctly interpreted in 99% of cases.

Objective To evaluate the accuracy and method of pedicle screw implantation in the thoracic and lumbar spine by funnel technique.

Objective: To discuss the use of pedicle screw system in thoracolumbar fracture and the prevention and treatment for the complications.

Methods 8 cases of failure thoracolumbar fractures treated with pedicle screw fixation were analyzed retrospectively.

Conclusion The method of pedicle screw implantation by funnel technique is scientific and feasible.

Abbreviations used in this paper: PS = pedicle screw.

Objective To analyze the pedicle screw fixation for thoracic and lumbar spine injury in effect.

The pedicle screw position was assessed with "C" arm fluoroscopy during operation.

The control group: the road of pedicle screw was ready with using an ordinary piercer.

Study Design. This is a diagnostic study in which cadavers were evaluated by imaging and dissection after pedicle screw placement.

A cannulated pedicle screw is placed over the guide wire.

Study Design. Pedicle screw pullout testing in osteoporotic and control human cadaveric ertebrae, comparing augmented and control ertebrae.

In addition, pedicle screw constructs appear to have a better ability to correct scoliosis in comparison with hooks and hybrid constructs.

Methods. Pedicle screw holes were placed in 24 pedicles of 2 postmortem human lumbar spine specimens.

Popular new surgical techniques, such as cervical pedicle screw or C1 lateral mass screw fixation, also entail the potential risk of VAI.
