Comparison of thoracic pedicle screw to hook instrumentation for the treatment of adult spinal deformity.
STUDY DESIGN Retrospective, case-control, matched cohort. OBJECTIVE Compare the radiographic and clinical outcomes of adult spinal deformity patients treated with thoracic pedicle screw (TPS) or thoracic hook constructs. SUMMARY OF BACKGROUND DATA The efficacy of TPS instrumentation for pediatric spinal deformity correction has been established. Little is known about TPS use in adult spinal...
متن کاملSacral screw loads in lumbosacral fixation for spinal deformity.
Fixation to the sacrum and pelvis is a problem in the operative treatment of spinal deformity. Previous testing of pedicle screws address axial pull-out strength, yet how screws are loaded in vivo remains unknown. The goals of this study were to determine the loads experienced by sacral screws when loaded as part of Cotrel-Dubousset (CD) sacral instrumentation and whether different anterior gra...
متن کاملA biomechanical comparison of a novel thoracic screw fixation method: transarticular screw fixation vs traditional pedicle screw fixation.
BACKGROUND Transarticular screw fixation is used in the upper cervical and lumbar spine to achieve posterior spinal stability, and its biomechanical performance has been proven to be similar to that of pedicle screw fixation. However, few studies have reported the use of transarticular screw fixation in the upper thoracic spine. OBJECTIVE To biomechanically compare transarticular screws with ...
متن کاملPedicle screw surface coatings improve fixation in nonfusion spinal constructs.
STUDY DESIGN Biomechanical and histologic analysis. OBJECTIVE To compare the strength of the bone-screw interface of standard uncoated pedicle screws with screws treated with hydroxyapatite (HA), titanium plasma spray (TPS), and a composite HA-TPS coating. SUMMARY OF BACKGROUND DATA Transpedicular screw fixation has become the gold standard in the treatment of various thoracolumbar spinal c...
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...
