Biomechanical Analysis of Pedicle Screw Fixation for Thoracolumbar Burst Fractures.
Treatment of unstable thoracolumbar burst fractures remains controversial. Long-segment pedicle screw constructs may be stiffer and impart greater forces on adjacent segments compared with short-segment constructs, which may affect clinical performance and long-term out come. The purpose of this study was to biomechanically evaluate long-segment posterior pedicle screw fixation (LSPF) vs short-...
متن کاملAccuracy of pedicle screw placement in thoracolumbar spine with conventional open technique.
AIM To demonstrate the incidence of screw misplacement and revision rates in a group of 72 patients that underwent pedicle screw fixation for spinal pathologies using the conventional, fluoroscopy-guided open technique. MATERIAL AND METHODS Data from 72 consecutive patients with spinal instability that received 472 screws between April 2011 and May 2013 were reviewed and pedicle wall breach w...
متن کاملaccuracy and complications of pedicle screw insertion for lumbar and thoracolumbar fractures
background: the accuracy of pedicle screw placement is essential for lumbar and thoracolumbar spine fracture fixation. purpose: the aim of the present study was to assess the accuracy of the pedicle screw placement with conventional c-arm fuoroscopy-guided in these patients. methods: a retrospective review identified patients who underwent operative management with thoracolumbar instruments at ...
متن کاملPedicle screw fixation combined with intermediate screw at the fracture level for treatment of thoracolumbar fractures
BACKGROUND Use of a pedicle screw at the level of fracture, also known as an intermediate screw, has been shown to improve clinical results in managing thoracolumbar(TL) fractures, but there is a paucity of powerful evidence to support the claim. The aim of this study was to compare outcomes between pedicle screw fixation combined with intermediate screw at the fracture level and conventional p...
متن کاملCT Assessment of accuracy of lumbar pedicle screw insertion
Methods: Data were collected from the Department of neurosurgery, Kasr Al-Ainy, Cairo University Hospital. The valid patient sample was collected (n0=103). In addition to the standard study protocol evaluation, patients were evaluated for the presence or absence of pedicle breach generally comparing both techniques (hypothesis 1), and comparing the degree of deviation between both techniques (h...
