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 ...
