OBJECTIVE To quantify changes in the diameter of the vertebral canal with flexion and extension in the cervical vertebral column. STUDY DESIGN Cadaveric biomechanical study. SAMPLE POPULATION Cadaveric canine cervical vertebral column (n = 16 dogs). METHODS All vertebral columns were evaluated with MRI. Group 1 consisted of 8 normal vertebral columns. Group 2 included 8 vertebral columns ...
There is little data on the diagnostic reliability of the ultrasonic Doppler technique for vertebral arterial occlusive lesions. Percutaneous vertebral Doppler examination and the vertebral angiograms were compared to determine the diagnostic reliability of this technique in 64 vertebral arteries of 53 patients with cerebrovascular disease. The percutaneous vertebral Doppler findings were quant...
complex vertebral malformation(cvm) isanautosomal recessivehereditarydisorder caused bya point mutation in position 559 inexon 4 of the slc35a3 gene on chromosome 3 inholstein dairy cattle.this mutationchanges the function of uridine 5-diphosphate-n-acetylglucosamine transporter protein bythe substitution of valine for phenylalanine at position 180 of this protein. the disease causes premature ...
Total and regional allometric growth rates and termination sites of the spinal cord related to the respective vertebra were studied in 36 goat fetuses, from the Ahvaz slaughterhouse. These specimens were assigned to 3 groups, group 1 (CRL 10-20 cm), group 2 (CRL 21-30 cm), and group 3 (CRL 31-40 cm), each consisting of 6 male and 6 female fetuses. Observations in all 3 groups revealed that alth...
This study aimed to investigate the clinical effect of percutaneous kyphoplasty and the precautions against adjacent vertebral refractures in the treatment of multiple osteoporotic vertebral compression fractures. 54 cases (128 vertebrae) with multiple osteoporotic vertebral compression fractures from July 2007 to December 2013 treated with percutaneous kyphoplasty were retrospectively reviewed...
PURPOSE To assess the association between vertebral fractures and mortality. METHODS 419 women and 210 men aged 60 to 98 (mean, 73) years participated in an osteoporosis screening exercise. Patient age, gender, comorbidity, lumbar pain, smoking, and alcohol consumption were recorded, as were the number of vertebral fractures and bone mineral density. Vertebral fractures were evaluated using l...
PURPOSE Vertebral fractures due to osteoporosis are a potential complication of childhood acute lymphoblastic leukemia (ALL). To date, the incidence of vertebral fractures during ALL treatment has not been reported. PATIENT AND METHODS We prospectively evaluated 155 children with ALL during the first 12 months of leukemia therapy. Lateral thoracolumbar spine radiographs were obtained at basel...
It has been our sincerest honor to have guest-edited this focus issue on “Disk Degeneration and Pain” for the Global Spine Journal. Of particular importance is that this issue commemorates the “first” focus issue of our newly developed journal, which we hope will be one of many more to come. In a recent publication by Vos et al,1 published by The Lancet, low back pain was identified as “the lea...
A 3-manifold with marked boundary is a pair (M, X), where M is a compact 3-manifold whose (possibly empty) boundary is made up of tori and Klein bottles, and X is a trivalent graph that is a spine of ∂M . A standard skeleton of a 3-manifold with marked boundary (M, X) is a standard sub-polyhedron P of M such that P ∩∂M coincides with X and with ∂P , and such that P ∪ ∂M is a spine of M \ B (whe...
The repeatability of instrumented assessments of postero-anterior (PA) movements has been reported previously for lumbar and thoracic spines, but only in relation to limited parameters of the movement. This study describes a device for measuring PA movements of the cervical spine and reports on repeatability of the entire force/displacement (FD) curves. Repeatability was assessed using coeffici...
