Clinical Accuracy of Three-Dimensional Fluoroscopy (IsoC-3D)-Assisted Upper Thoracic Pedicle Screw Insertion [PDF]

, 2010
Correct screw placement is especially difficult in the upper thoracic vertebrae. At the cervicothoracic junction (C7-T2), problems can arise because of the narrowness of the pedicle and the difficulty of using a lateral image intensifier there.

Biomechanical comparison of cervical transfacet pedicle screws versus pedicle screws

Chinese Medical Journal, 2008
Transfacet pedicle screws provide another alternative for standard pedicle screw placement for plate fixation in the lumbar spine. However, few studies looking at transfacet pedicle screw fixation in the cervical spine are available. Therefore, cervical transfacet pedicle screw fixation and standard pedicle screw fixation techniques were ...

Review of currently used classifications for pedicle screw position grading in cervical, thoracic and lumbar spine [PDF]

Chirurgia Narządów Ruchu i Ortopedia Polska, 2023
Pedicle screw fixation technique has been established as the safe standard for instrumentations in all spinal regions. However, the screw position is sometimes suboptimal. Cortical breaches may occur in different regions of the vertebrae.
