BACKGROUND CONTEXT: In today's healthcare climate, Magnetic Resonance Imaging (MRI) is often perceived as a commodity - a service where there are no meaningful differences in quality and thus an area in which patients can be advised to select a provider based on price and convenience alone. If this prevailing view is correct, then a patient should expect to receive the same radiological diagnosis regardless of which imaging center he or she visits or which radiologist reviews the examination...

BACKGROUND: Context : More than half of the perforations reported with usage of cervical pedicle screws (CPS), are lateral perforations, endangering the vertebral artery. The medial cortical pedicle screw technique (MCPS) with partial drilling of the medial cortex, shifts the trajectory of pedicle screws medially, decreasing the lateral perforations. PURPOSE: To evaluate the decrease in lateral perforations of CPS with use of MCPS technique, in relation to medial angulation...

BACKGROUND: Injectable, brushite-forming calcium phosphate cements (CPC) show potential for bone replacement, but they exhibit low mechanical strength. This study tested a CPC reinforced with poly (l-lactide-co-glycolide) acid (PLGA) fibers in a minimally-invasive, sheep lumbar vertebroplasty model. PURPOSE: To test the in vivo biocompatibility and osteogenic potential of a PLGA fiber-reinforced, brushite-forming CPC in a sheep large animal model. STUDY DESIGN/SETTING: Prospective experimental animal study METHODS: Bone defects (diameter 5 mm) were placed in aged, osteopenic female sheep and left empty (L2) or injected with pure CPC (L3) or PLGA-fiber-reinforced CPC (L4; fiber diameter 25 µm; length 1 mm; 10% (w/w))...

BACKGROUND CONTEXT: Adult spinal deformity correction sometimes involves long posterior pedicle screw constructs extending from the lumbosacral spine to the thoracic vertebra. As fusion obliterates motion and places supraphysiological stress on adjacent spinal segments, it is crucial to ascertain the ideal upper instrumented vertebra (UIV) to minimize risk of proximal junctional failure (PJF). The T10 vertebra is often chosen to allow bridging of the thoracolumbar junction into the immobile thoracic vertebrae on the basis that it is the lowest immobile thoracic vertebra strut by the rib cage...

BACKGROUND CONTEXT: Many radiological parameters have been reported to correlate with patient's disability including sagittal vertical axis (SVA), pelvic tilt (PT), and pelvic incidence minus lumbar lordosis (PI-LL). European literature reports other parameters such as lumbar lordosis index (LLI) and the global tilt (GT). If most parameters correlate with health-related quality of life scores (HRQLs), their impact on disability remains unclear. PURPOSE: This study aimed to validate these parameters by investigating their correlation with HRQLs...

BACKGROUND: Inconsistent associations between modifiable risk factors and chronic back pain (CBP) may be due to the inability of traditional epidemiologic study designs to properly account for an array of potential genetic and environmental confounding factors. The co-twin control research design, comparing modifiable risk factors in twins discordant for CBP, offers a unique way to remove numerous confounding factors. PURPOSE: The study aimed to examine the association of modifiable lifestyle and psychological factors with lifetime CBP...

BACKGROUND CONTEXT: Degenerative Cervical Myelopathy (DCM) represents the most common cause of non-traumatic spinal cord impairment in adults. Surgery has been shown to improve neurological symptoms and functional status, but it is costly. As sustainability concerns in the field of healthcare rise, the value of care has come to the forefront of policy decision-making. Evidence for both health related quality of life outcomes and financial expenditures are needed to inform resource allocation decisions...

BACKGROUND: Research suggests that people with lumbar spinal stenosis (LSS) would benefit from increased physical activity. Yet, to date we do not have disease specific activity guidelines for LSS, and the nature of free-living physical activity (performance) in LSS remains unknown. LSS care providers could endorse the 2008 United States Physical Activity Guidelines, however, we do not know if this is realistic. The goal of this study was to determine the proportion of individuals with LSS meeting the 2008 Guidelines...
