Three-dimensional computed tomography assisted cervical pedicle screw fixation;

Biomechanics of the effects of bone cement on strengthening and revising of pedicle screw in osteoporotic vertebra;

Computed tomography study of the anatomic feasibility of C_2 pedicle screw placement;

Complications associated with pedicle screws;

Purpose To evaluate the accuracy of computer-assisted fluoroscopy for the placement of thoracic and lumbosacral pedicle screws in cadaver specimens.

Objective To investigate the surgical strategy for degenerative scoliosis and evaluate the clinical effect of pedicle screws in correction based on related clinical review.

Treatment of lower lumbar fracture with vertebral pedicle screw;

Surgical treament of thoracolumbar burst fracture with extension reduction and short-segment pedicle screw system fixation;

Aim:Assessment of the clinical result of different ways of bone autografting in spine with RF and TRFIX pedicle screw system.

Conclusions: The technique of pedicle screw system has the advantages of saving time and medical materials,increasing the efficiency of treatment,and relieving the syptoms of the patients.
