Comparison of superior-level facet joint violations during open and percutaneous pedicle screw placement.
BACKGROUND Superior-level facet joint violation by pedicle screws may result in increased stress to the level above the instrumentation and may contribute to adjacent segment disease. Previous studies have evaluated facet joint violations in open or percutaneous screw cases, but there are no reports describing a direct institutional comparison. OBJECTIVE To compare the incidence of superior-l...
متن کاملComparison of Cranial Facet Joint Violation Rate Between Percutaneous and Open Pedicle Screw Placement
Percutaneous and open pedicle screw placements have been widely used in lumbar fusion surgery. However, there are conflicting reports of cranial facet joint violation rate for the 2 techniques. To better determine the rate of cranial facet joint violation, a systematic review and meta-analysis was performed in the present study. We searched the established electronic literature databases includ...
متن کاملPedicle screw placement accuracy impact and comparison between grading systems
BACKGROUND Pedicle screw instrumentation is widely used for spinal stabilization. However, the accuracy for free-hand screw placement ranges from 69% to 94%. This study assesses the value of the existing classification systems, and investigates their impact on the ability to assess the accuracy of free-hand screw placement. METHODS Data were collected retrospectively from the medical records ...
متن کاملThoracic pedicle screw placement: free-hand technique.
Thoracic pedicle screws provide a number of advantages over other methods of spinal fixation in treating a variety of conditions including: better pull-out strength and greater control in the sagittal, coronal and rotational planes due to increased stability to axial, bending and rotational forces by three-column fixation, fewer vertebral motion segments arthrodesed, no or lessened need for pos...
متن کاملPedicle screw placement in patients with variant atlas pedicle
OBJECTIVE To investigate how the anatomy of variant atlas vertebra impacts on the strategy used to place pedicle screws used to treat atlantoaxial instability. METHODS The study enrolled patients with cervical instability who had a posterior arch pedicle height <3.5 mm at the anchor point, a vertebral artery groove height <3.5 mm, or both. Pedicle screws were fitted according to the anatomy o...
