Short Segment versus Long Segment Pedicle Screws Fixation in Management of Thoracolumbar Burst Fractures: Meta-Analysis
Posterior pedicle screw fixation has become a popular method for treating thoracolumbar burst fractures. However, it remains unclear whether additional fixation of more segments could improve clinical and radiological outcomes. This meta-analysis was performed to evaluate the effectiveness of fixation levels with pedicle screw fixation for thoracolumbar burst fractures. MEDLINE, EMBASE, the Coc...
متن کاملBiomechanical 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 کاملSurgical outcomes of short-segment fixation for thoracolumbar fracture dislocation.
BACKGROUND Currently long-segment pedicle instrumentation for a thoracolumbar (T-L) fracture-dislocation is gaining in popularity. Otherwise, short-segment fixation may be chosen as an another treatment method. This article evaluates the efficacy and complications of short-segment fixation for the treatment of thoracic or lumbar spine fracture-dislocation. METHODS Twenty patients with thoraci...
متن کاملComparison of short-segment versus long-segment fixation for the treatment of thoracolumbar burst fracture: a meta-analysis
Background: Thoracolumbar burst fracture is one of the most common spinal traumas. It was still indeterminate whether short-segment (SS) fixation was more effective and preferable than long-segment (LS) fixation. We therefore conducted this meta-analysis to assess the comparative safety and efficacy of SS and LS fixation for the treatment of thoracolumbar burst fracture. Methods: A literature s...
متن کاملFactors predicting long-term outcome after short-segment posterior fixation for traumatic thoracolumbar fractures
BACKGROUND The "gold standard" for instrumentation of unstable thoracolumbar fracture-dislocations is pedicle screw and rod fixation. Although traditional treatment supports long-segment posterior fixation (LSPF), more recent studies show short-segment posterior fixation (SSPF) may be effective, but incur higher failure rates. Here, we evaluated the effectiveness of SSPF in the management of un...
