Atlantoaxial Transpedicular Screw Fixation for the Management of Traumatic Upper Cervical Spine Instability
Objective: The morbidity and mortality are high for traumatic upper cervical spine instability with cervico-medullary compression. In a clinical retrospective study, the clinical and radiographic results of occipitocervical (OC) fusion using posterior atlantoaxial transpedicular screw fixation in 12 patients with traumatic upper cervical spine instability was reviewed. Methods: Twelve patients ...
متن کاملA Novel Anterior Transpedicular Screw Artificial Vertebral Body System for Lower Cervical Spine Fixation: A Finite Element Study.
A finite element model was used to compare the biomechanical properties of a novel anterior transpedicular screw artificial vertebral body system (AVBS) with a conventional anterior screw plate system (ASPS) for fixation in the lower cervical spine. A model of the intact cervical spine (C3-C7) was established. AVBS or ASPS constructs were implanted between C4 and C6. The models were loaded in t...
متن کاملBiomechanical analysis of transpedicular screw fixation in the subaxial cervical spine.
STUDY DESIGN An in vitro biomechanical study to compare 2 different dorsal screw fixation techniques in the cervical spine with respect to primary stability and stability after cyclic loading. OBJECTIVES To investigate if the biomechanical stability is better in pedicle screw or in lateral mass fixation. SUMMARY OF BACKGROUND DATA In patients with poor bone quality who require multisegmenta...
متن کاملAnterior Transpedicular Screw-Plate System Fixation in the Lower Cervical Spine Fracture Complicated by Spinal Cord Injury: A Case Report
A multilevel contiguous fracture of the subaxial cervical spine represents the severe trauma, and anterior plate fixation with anterior transpedicular screw fixation is a new and reliable fixation pattern for the treat-ment of acute spinal cord injury (ASCI). We present a case of multilevel contiguous fractures in the lower cervical spine without obvious posterior ligamentous complex injury, bu...
متن کاملTranspedicle screw fixation of the cervical spine.
The use of posterior cervical spine fixation has become increasingly popular in recent years. Dissatisfaction with lateral mass fixation, especially at the cervicothoracic junction, has led spine surgeons to use cervical pedicle screw fixation for reconstruction in numerous cervical spine disorders. The biomechanical advantage of a three-column fixation device implanted to secure an unstable ce...
