Study Design. Retrospective evaluation of complications in 180 consecutive patients with cervical disorders who had been treated by using pedicle screw fixation systems. Objectives. To determine the risks associated with pedicle screw fixation in the cervical spine and to emphasize the importance of preoperative planning and surgical techniques in reducing the risks of this procedure. Summary of Background Data. Generally, pedicle screw fixation in the cervical spine has been considered too… 

Reconstruction of the Subaxial Cervical Spine Using Pedicle Screw Instrumentation

Pedicle screw provides excellent 3-dimensional fixations and is a useful procedure for reconstruction of the cervical spine in various kinds of disorders and can be minimized by sufficient preoperative imaging studies and strict control of screw placement during surgery.

Minimally Invasive Cervical Pedicle Screw Fixation by a Posterolateral Approach for Acute Cervical Injury

In this study, incidence of screw perforation was significantly lower in the MICEPS fixation group than in the conventional cervical pedicle screw group, and neither of the misplaced screws was laterally deviated in theMICEPS group.

Spinal Reconstruction Using a Cervical Pedicle Screw System

Clinical results of the cervical pedicle screw system were excellent with few complications, but there is the possibility of screw perforation, which could cause neurovascular complications, so increased accuracy of screw insertion is needed to make this instrumentation safer.

Placement and complications of cervical pedicle screws in 144 cervical trauma patients using pedicle axis view techniques by fluoroscope

The placement of cervical pedicle screws using a fluoroscopy-assisted pedicle axis view technique provided good clinical results and a few complications for unstable cervical injuries, but a careful surgical procedure was needed to safely insert the screws and more improvement in imaging and navigation system is expected.

Cervical Pedicle Screws: Conventional Versus Computer-Assisted Placement of Cannulated Screws

Transpedicular screws in the cervical spine and cervicothoracic junction can be applied safely and with high accuracy in a conventional technique and the use of a CAS system seems to be beneficial, especially for pedicle instrumentation C3–C6.

Surgical Outcomes and Complications of Pedicle Screw Fixation in 200 Cases of unstable Cervical Spinal Injuries-Comparison between Plate Systems and Rod Systems -

Cervical pedicle screw fixation using a fluoroscopy assisted pedicle axis view technique provided good clinical result in both plate and rod systems, comparing plate systems.

Complications of cervical pedicle screw fixation for nontraumatic lesions: a multicenter study of 84 patients.

Surgeons should use PS fixation for nontraumatic cervical lesions only after thorough preoperative evaluation of each patient's cervical anatomy and after considering the risk factors specified in the present study, which occurred more often than in previous studies.

Management of fracture-dislocation of the lower cervical spine with the cervical pedicle screw system.

The cervical pedicle screw system is an effective and reliable method for the restoration of cervical stability and pre-operative imaging studies of the pedicles and strict screw insertion technique should be emphasised.



Pedicle Screw Fixation for Nontraumatic Lesions of the Cervical Spine

Pedicle screw fixation is a useful procedure for posterior reconstruction of the cervical spine, and should be especially valuable for simultaneous posterior decompression and fusion.

Complications of Posterior Articular Mass Plate Fixation of the Subaxial Cervical Spine in 43 Consecutive Patients

Lateral mass plate fixation is safe and effective with the authors' surgical technique, and Posterior cervical plate stabilization is a viable alternative to more traditional wiring techniques.

Posterior Cervical Arthrodesis and Stabilization With a Lateral Mass Plate: Clinical and Computed Tomographic Evaluation of Lateral Mass Screw Placement and Associated Complications

Lateral mass plating was associated with no vertebral artery or spinal cord injury and there was a 1.8%-per-screw risk of radiculopathy, which corresponds with published cadaveric studies.

Posterior occipitocervical reconstruction using cervical pedicle screws and plate-rod systems.

Results of this study showed the effectiveness of cervical pedicle screw as a fixation anchor for occipitocervical reconstruction, which provided the high fusion rate and sufficient correction of malalignment in the occipitoatlantoaxial region.

Complications of Posterior Cervical Plating

Cadaveric work has predicted certain anatomic complications rates associated with lateral mass screw insertion, but this study finds the risk of lateralmass screw insertion to be considerably less than predicted in vitro.

Cervical Pedicle Screws Versus Lateral Mass Screws: Anatomic Feasibility and Biomechanical Comparison

Cervical pedicle screws demonstrated a significantly higher resistance to pull-out forces than did lateral mass screws, and the variability in pedicle morphometry and orientation requires careful preoperative assessment to determine the suitability of pedicle screw insertion.

Anatomical and morphometric studies in posterior cervical spinal screw-plate systems.

Radiographic analysis of the specimens and cryoplaning after implant removal and casting of the screw-plate cavities showed significant differences of the four systems with respect to effective screw length, possible and desirable screw trajectories, and risk for injuries of the facet joints, foraminal neurovascular elements, and vertebral artery.

Rigid internal fixation with lateral mass plates in multilevel anterior and posterior reconstruction of the cervical spine.

Segmental posterior fixation with lateral mass plating provides more rigid immobilization than traditional techniques, allows restoration and maintenance of spinal alignment, obviates the need for halo immobilization, and is associated with a low incidence of neurovascular injury.

Biomechanical Analysis of Cervical Stabilization Systems: An Assessment of Transpedicular Screw Fixation in the Cervical Spine

Front and back approaches, employing the anterior plate and posterior triple-wiring, and transpedicular screw fixation demonstrated clear biomechanical advantages when the extent of instability increased to three-column or multilevel.

Morphometric Evaluation of Lower Cervical Pedicle and Its Projection

Taking into consideration some variations between individuals, this information, combined with evaluation of results of preoperative axial computed tomography and conventional radiography, may enhance the safety of transpedicular screw fixation in the lower cervical spine.
