BACKGROUND AND PURPOSE The diagnosis of traumatic spinal dural tears is difficult to establish. The purpose of this study was to determine the reliable MR imaging findings suggesting dural tears in spinal burst fractures. MATERIALS AND METHODS We retrospectively reviewed spine MR images of 21 patients with dural tears (study group) and 33 patients without dural tears (control group), all of w...

STUDY DESIGN A systematic quantitative review of the literature. OBJECTIVE To compare combined anterior-posterior surgery versus posterior surgery for thoracolumbar fractures in order to identify better treatments. SUMMARY OF BACKGROUND DATA Axial load of the anterior and middle column of the spine can lead to a burst fracture in the vertebral body. The management of thoracolumbar burst fra...

PURPOSE Surgical treatment in the case of thoracolumbar burst fractures is very controversial. Posterior instrumentation is most frequently used, however, but the number of levels to be instrumented still remains a matter of debate. MATERIALS AND METHODS A total of 94 patients who had a single burst fracture between T11 and L2 were selected and were managed using posterior instrumentation wit...

OBJECTIVE A thoracolumbar burst fracture is usually unstable and can cause neurological deficits and angular deformity. Patients with unstable thoracolumbar burst fracture usually need surgery for decompression of the spinal canal, correction of the angular deformity, and stabilization of the spinal column. We compared two struts, titanium mesh cages (TMCs) and expandable cages. METHODS 33 pa...

A finite element model of the T12-L1 motion segment was subjected to dynamic vertical impact to investigate vertebral burst fracture mechanism at the thoracolumbar junction. A rigid ball was directed vertically towards a rigid plate fixed on top of the T12 vertebral body to simulate the axial impact. The results show that upon impact, the T12 vertebra exhibited a vibratory motion. At its maximu...

OBJECTIVE Evaluate incidence of Magerl's A and B group in thoracolumbar burst fracture (Denis) according to independent examiners. METHOD According to the posterior spinous process split on the anterior posterior radiography, three independent examiners have analyzed the patients admitted from 2000 to 2009 with thoracolumbar burst fractures (according to Denis) to differentiate between Magerl...

BACKGROUND Currently, Posterior Short Segment Pedicle Screw Fixation is a popular procedure for treating unstable thoracolumbar/lumbar burst fracture. But progressive kyphosis and a high rate of hardware failure because of lack of the anterior column support remains a concern. The efficacy of different methods remains debatable and each technique has its advantages and disadvantages. METHODS ...

BACKGROUND Posterior pedicle screw fixation has become a popular method for treating thoracolumbar burst fractures. However, it remains unclear whether additional fusion could improve clinical and radiological outcomes. This meta-analysis was performed to evaluate the effectiveness of fusion as a supplement to pedicle screw fixation for thoracolumbar burst fractures. METHODOLOGY/PRINCIPAL FIN...

OBJECTIVE Posterior longitudinal ligament reduction (PLLR) has been widely used for treatment of thoracolumbar burst fractures. However, there are no systemic studies assessing the influence of position parameters of intra-canal fracture fragment (IFF) itself on outcome of reduction. The aim of this study was to analyze the relationship between position parameters of IFF and the reduction effic...
