Bone marrow fat quantification of osteoporotic vertebral compression fractures: comparison of multi-voxel proton MR spectroscopy and chemical-shift g…
2011
Background Only a few studies have used in/opposed phase method for a quantitative evaluation of fat fraction in the spine. Purpose To compare multivoxel proton MR spectroscopy and chemical-shift gradient-echo MR imaging for bone marrow fat quantification in vertebral compression fractures (VCF). Material and Methods Vertebral marrow fat quantification in fifteen patients was measured at 3.0-T. Multi-voxel proton spectroscopy (MRS) and in/opposed-phase MR imaging using a fat map build with a triple-echo gradient-echo sequence was used. All the patients had benign vertebral collapse. Bone marrow fat content was evaluated by both techniques in compressed (acute or chronic) and in non-compress…
Atlases with Arcuate Foramen Present Cortical Bone Thickening That May Contribute to Lower Fracture Risk.
2018
To date, no information about the cortical bone microstructural properties in atlas vertebrae with arcuate foramen has been reported. As a result, we aimed to test in an experimental model if there is a cortical bone thickening in an atlas vertebra which has an arcuate foramen that may play a protective role against bone fracture.We analyzed by means of micro-computed tomography the cortical bone thickness, the cortical volume, and the medullary volume (SkyScan 1172 Bruker micro-CT NV, Kontich, Belgium) in cadaveric dry atlas vertebrae with arcuate foramen and without arcuate foramen. We also reviewed a case series of 31 posterior atlas arch fractures to correlate the possible presence in t…
EMG-guided percutaneous placement of cement-augmented pedicle screws for osteoporotic thoracolumbar burst fractures
2017
Background: Percutaneous techniques have increasingly gained popularity in recent years. The application of technological innovation, including neuromonitoring techniques, has the potential to increase the safety and efficacy of these procedures. Methods: Thirty patients suffering from osteoporotic dorsolumbar burst fracture were prospectively enrolled in this study. The patients underwent percutaneous fenestrated pedicle screw fixation augmented with polymethylmethacrylate (PMMA) injection. A novel surgeon-dedicated neuromonitoring device was used in order to increase the safety and the accuracy of the screw insertion. A second group of 30 patients who did not undergo neuromonitoring durin…
High prevalence of fragility vertebral fractures in patients hospitalised in Internal Medicine Units. Results of the POINT (Prevalence of Osteoporosi…
2015
Abstract Background Osteoporotic vertebral fractures (VFs) often go unrecognised in both healthy individuals and in pathological conditions. Few data exist on VFs in patients hospitalised in Internal Medicine Units (IMUs), who often suffer from multiple concomitant chronic disorders. Aim of the study This multicentre cross-sectional study was aimed at assessing the prevalence of VFs in an unselected population of patients referring to IMUs. Correlations between VFs and the main coexisting diseases were also investigated. Methods Information on demographic, clinical and laboratory findings, and on the presence of known risk factors for osteoporosis was recorded. The Genant's semi-quantitativ…
Two-year results of vertebral body stenting for the treatment of traumatic incomplete burst fractures.
2014
Vertebral body stenting (VBS) was developed to prevent loss of reduction after balloon deflation during kyphoplasty. The aim of this study is the radiological and clinical mid-term evaluation of traumatic incomplete burst fractures treated by vertebral body stenting.This retrospective study included patients with traumatic thoracolumbar incomplete burst fractures treated with VBS between 2009 and 2010. The outcome was evaluated with the visual analogue pain scale (VAS), the Oswestry Disability Score (ODI), the SF-36 Health Survey and radiologically assessed.Eighteen patients with an average age of 74.8 years were treated with VBS. Twelve were female and six were male. Two years after the op…
The prevalence of vitamin D deficiency in patients with vertebral fragility fractures
2015
Hypovitaminosis D has been identified as a common risk factor for fragility fractures and poor fracture healing. Epidemiological data on vitamin D deficiency have been gathered in various populations, but the association between vertebral fragility fractures and hypovitaminosis D, especially in males, remains unclear. The purpose of this study was to evaluate serum levels of 25-hydroxyvitamin D (25-OH D) in patients presenting with vertebral fragility fractures and to determine whether patients with a vertebral fracture were at greater risk of hypovitaminosis D than a control population. Furthermore, we studied the seasonal variations in the serum vitamin D levels of tested patients in ord…
The incidence of hip, forearm, humeral, ankle, and vertebral fragility fractures in Italy: results from a 3-year multicenter study
2010
Introduction: We aimed to assess the incidence and hospitalization rate of hip and "minor" fragility fractures in the Italian population.Methods: We carried out a 3-year survey at 10 major Italian emergency departments to evaluate the hospitalization rate of hip, forearm, humeral, ankle, and vertebral fragility fractures in people 45 years or older between 2004 and 2006, both men and women. These data were compared with those recorded in the national hospitalizations database (SDO) to assess the overall incidence of fragility fractures occurring at hip and other sites, including also those events not resulting in hospital admissions.Results: We observed 29,017 fractures across 3 years, with…
Polymyalgia rheumatica and vertebral fractures: a 1-year pilot controlled study
2010
No data exist about the possibility that vertebral fracture in PMR patients could be independent of steroid therapy. For this reason, we aimed to investigate this topic by a case cohort study with a 1-year follow-up for each patient. We selected ten consecutive patients who experienced vertebral fractures (VF-group) during the first month of 1-year follow-up period and without any other significant associated condition. As a control group we studied ten control patients, without vertebral fractures and with a follow-up of 1 year, randomly selected among a larger group of patients affected by polymyalgia rheumatica. The following data were analysed: eritrosedimention rate (ESR), visual analo…
Difficulties in distinguishing between an atlas fracture and a congenital posterior atlas arch defect in postmortem analysis.
2013
We found one atlas from a sample of 148 skeletons (0.67%) that presented different anatomical variations which made it difficult to determine whether the vertebra had an atlas fracture, an unusual Type B posterior atlas arch defect, or a combination of both. We carried out a stereomicroscopy, radiographic, and computerized tomography scan study that revealed that the dry atlas we found presented a very uncommon congenital Type B posterior atlas arch defect, simulating a fracture. In short, the present paper has revealed that differentiating Type B posterior atlas arch defects from fractures in post-mortem dry vertebrae is more difficult than expected. Thus we believe that it can be easier t…
Management of Odontoid Cervical Fracture
2019
Fractures of the cervical odontoid process are the most common fractures of the cervical tract, accounting for one third of all cervical spine fractures. They are more frequent in elderly patients, and with the aging of the world population, their incidence and clinical and social relevance are expected to increase in the near future. The mechanisms underlying odontoid fractures differ according to patient age, with high-energy mechanisms being the causative factor frequently encountered in younger patients and low-energy trauma commonly occurring in elderly patients. Despite rising incidence and costs, there is considerable uncertainty regarding the optimal management for these fractures, …
