The Mechanical Effect of Rod Contouring on Rod-Screw System Strength in Spine Fixation
OBJECTIVE Rod-screw fixation systems are widely used for spinal instrumentation. Although many biomechanical studies on rod-screw systems have been carried out, but the effects of rod contouring on the construct strength is still not very well defined in the literature. This work examines the mechanical impact of straight, 20° kyphotic, and 20° lordotic rod contouring on rod-screw fixation syst...
متن کاملUse of screw-rod system in occipitocervical fixation.
BACKGROUND This study retrospectively reviewed 9 patients who underwent occipitocervical fixation with a newly developed screw-rod fixation system between April 2004 and November 2005. The objective was to evaluate the clinical result of occipitocervical fixation with the screw-rod fixation system, including symptom relief, fusion rate and complications. METHODS All 9 patients received occipi...
متن کاملPosterior atlantal lateral mass fixation technique with polyaxial screw and rod fixation system.
OBJECTIVE Atlantoaxial instability may result from various pathologic conditions and operative treatment may be required to correct the deformity, provide stability and prevent neurological deficits. We presented our clinic's experience using C1-C2 fusion with polyaxial screw and rod fixation for C1 and C2 instability for various reasons. METHODS AND MATERIAL Four patients with atlantoaxial i...
متن کاملDesign and performance of spinal fixation pedicle screw system.
Pedicle screw-rod bilateral constructions are extensively used in spinal fixation. In this study, the common cause for failure of bilateral constructions has been determined to be the high stress concentration at the rod-setscrew interface. In order to overcome this problem, a design modification has been made by using a supplementary part (shoe) between rod and setscrew. Performance comparison...
متن کاملBiomechanical comparison of two stabilization techniques of the atlantoaxial joints: transarticular screw fixation versus screw and rod fixation.
OBJECTIVE To compare the biomechanical stability imparted to the C1 and C2 vertebrae by either transarticular screw fixation (TSF) or screw and rod fixation (SRF) techniques in a cadaver model. METHODS Ten fresh ligamentous human cervical spine specimens were harvested from cadavers. The specimens were tested sequentially in the intact state, after injury and stabilization (unilateral left si...
