OBJECTIVE: The purpose of this meta-analysis was to compare the efficacy and safety between patients with thoracolumbar burst fracture who underwent posterior fixation alone (non-fusion) and supplemented with fusion. METHODS: A comprehensive search of related literature was performed in PubMed, Embase and the Cochrane library. Clinical outcomes (LBOS and VAS), surgical outcomes (operation time, blood loss, hospital stay and perioperative complications), and radiographic outcomes (kyphotic angle, decreased vertebral body height and segmental motion) were assessed in the meta-analysis...

The purpose of this study was to investigate cement leakage (CL) in osteoporotic vertebral compression fractures (OVCFs) with cortical defect using high-viscosity bone cement during unilateral percutaneous kyphoplasty (PKP) surgery.This study included a series of 77 patients (23 males, 54 females) with single level osteoporotic vertebral body fracture (OVCF) who underwent unilateral PKP in our hospital. Preoperative x-ray, computed tomography (CT) scan, and 3-dimensional reconstructions were studied. During the PKP procedure, needle was carefully put to avoid too near to the cortical defect according to CT image...

OBJECTIVE: Radiologists interpreting body CT scans may be the first to identify osteoporosis and associated vertebral fractures. This study correlates L1 trabecular attenuation measurements with prevalent vertebral body fractures in older adults undergoing routine CT. MATERIALS AND METHODS: Mean L1 trabecular attenuation was measured at thoracoabdominal CT in 1966 consecutive adults (983 men and 983 women) 65 years and older (mean age, 74.1 ± 6.6 [SD] years). Sagittal reconstructions and lateral scouts were analyzed for moderate or severe thoracolumbar vertebral compression fractures according to the Genant semiquantitative assessment method...

BACKGROUND: Traditional one-above and one-below four-screw posterior short-segment instrumentation is used for unstable thoracolumbar burst fractures. However, this method has a high rate of implant failure and early loss of reduction. The purpose of this study was to use finite element (FE) analysis to determine the effect of treating thoracolumbar burst fractures by short-segment pedicle screw fixation using a combination of two additional pedicle screws and vertebroplasty at the level of the fracture...

OBJECTIVE Percutaneous instrumentation in thoracolumbar fractures is intended to decrease paravertebral muscle damage by avoiding dissection. The aim of this study was to compare muscles at instrumented levels in patients who were treated by open or percutaneous surgery. METHODS Twenty-seven patients underwent open instrumentation, and 65 were treated percutaneously. A standardized MRI protocol using axial T1-weighted sequences was performed at a minimum 1-year follow-up after implant removal. Two independent observers measured cross-sectional areas (CSAs, in cm(2)) and region of interest (ROI) signal intensity (in pixels) of paravertebral muscles by using OsiriX at the fracture level, and at cranial and caudal instrumented pedicle levels...

PURPOSE: This retrospective study determined the rate of osteoarthritis and spontaneous facet joint fusion and analyzed risk factors related to patient characteristics, fracture type or surgical technique on pre- and postoperative CT after percutaneous instrumentation in thoracolumbar fractures. METHODS: 1050 facet joints adjacent to screws in 148 patients (15-85 years) with thoracolumbar fractures were analyzed with an average time between CTs of 12.3 months...

STUDY DESIGN: Reliability study of radiographic measures of proximal junctional kyphosis in adult spinal deformity patients. OBJECTIVE: Assess impacts of level of proximal endpoint and vertebral fracture on reliability of measurement of junctional kyphosis. SUMMARY OF BACKGROUND DATA: Radiographic assessment is important in determining management of patients with Proximal Junctional Kyphosis (PJK) or Proximal Junctional Failure (PJF). No study to date has evaluated the reliability of radiographic measurement of the junctional kyphotic angle after surgery for Adult Spinal Deformity (ASD)...

OBJECTIVE: This study mainly aimed to evaluate complications of cement leakage for osteoporotic thoracolumbar vertebral compression fractures by PVP using HVC, and access the clinical efficacy. METHODS: Between May 2013 and June 2015, 66 patients with osteoporotic thoracolumbar vertebral compression fractures, who underwent PVP (36 HVC and 30 LVC) in our hospital, were enrolled. Cement leakage, Visual Analog Scale (VAS), Oswestry Disability Index (ODI), refracture of the cemented vertebrae, and adjacent vertebral fractures were evaluated...

OBJECTIVE: To analyse the radiological outcomes in the long term of unstable thoraco-lumbar fractures. MATERIAL AND METHODS: Retrospective review of 100 patients with unstable thoracolumbar fractures treated with posterolateral fusion and short screw fixation for compression and flexion-distraction type fractures, and long segment posterior fixation for fractures-dislocations or more than one vertebra fractured, between 2000 and 2010 at three different hospital centers...

INTRODUCTION: Burst fractures of the spine account for 14% of all spinal injuries and more than 50% of all thoracolumbar trauma. However, there is ambiguity while choosing the right treatment plan. Short Segment Pedicle screw Fixation (SSPF) has become an increasingly popular method of treatment of thoracolumbar burst fractures, providing the advantage of incorporating fewer motion segments in the fixation. Various biomechanical studies showed that the use of pedicle screws could achieve stable construct within short-segment fixation...

BACKGROUND: This study attempts to prove a cause and effect relationship between spine immobilization following posterior fixation for unstable burst fractures and degeneration observed following hardware removal. METHODS: We enrolled 57 patients (259 intervertebral discs [IVDs]) who underwent only posterior instrumentation without fusion for thoracolumbar and lumbar unstable burst fractures. We arbitrarily named the IVD that has an endplate fracture after immobilization using pedicle screws as the fractured endplate and immobilized disc (FEID), the IVD that has no endplate fracture after immobilization using pedicle screws as the nonfractured endplate and immobilized disc (NFEID), and the IVD that has no endplate fracture and no immobilization instrumentation as the normal disc (ND)...

In a random sample of postmenopausal Chinese women, the prevalence of radiographic vertebral fractures increased from 13% between ages 50 and 59 to over 50% after age 80 years. A model with seven clinical risk factors predicted the probability of vertebral fractures as well with as without BMD and better than a model with only three risk factors. More than half an hour of outdoor activity per day might correlate with lower risk of vertebral fracture in this population. INTRODUCTION: We aimed to describe the prevalence and develop a model for prediction of radiographic vertebral fractures in a large random sample of postmenopausal Chinese women...

STUDY DESIGN: A randomized clinical trial. OBJECTIVE: To compare the functional recovery between early kyphoplasty and conservative care in paratroopers with stable thoracolumbar fractures. SUMMARY OF BACKGROUND DATA: Treatment of traumatic stable thoracolumbar fractures in young individuals is still a debate. Conservative management and kyphoplasty are options of therapy. But enough data are not available for supporting each. METHODS: We included 70 paratroopers with stable thoracolumbar fractures (A1 and A2 classification according to AOSpine thoracolumbar spine injury classification system) presenting <60 days after trauma and hyperintensity in T2-weighted magnetic resonance imaging...

OBJECTIVE: To describe a new technique for the efficient use of preoperative planning based on preoperative CT-based 3-Dimensional model design for percutaneous vertebroplasty (PVP) in a patient with osteoporotic vertebral compression fracture (OVCF). METHODS: A 76-year-old woman with acute OVCF (L1 level) accepted a novel precise PVP. A 3D model of thoracolumbar vertebrae (T12-L2) based on preoperative CT scanning data and a simulative PVP (via bilateral transpedicular approach) were built in Materiaise's interactive medical image control system (MIMICS) software...

STUDY DESIGN: Retrospective chart review. OBJECTIVE: The study purpose was to examine the feasibility of acute (<24 hours) and hyper-acute (<8 hours) treatment of thoracolumbar burst fractures to maintain or improve spinal injury scores. SUMMARY OF BACKGROUND DATA: Historically, treatment of spinal burst fractures within 24 hours from injury was considered an "acute" treatment timeframe. Patient polytrauma triage, multiple surgical specialty and hospital resource coordination affect time to treatment...
