На примере группы из 141 пациента (от 21 до 88 лет) при тщательном соблюдении одинакового увеличения цифровых рентгенограмм было показано, что метрическая длина отрезка касательной к изображению нижнего контура тела позвонка CI – эталон óрел – не имеет возрастного тренда.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Выявлено, что соотношение размеров эталона óрел (отрезка orel) и отрезка касательной к изображению верхнего контура крестца (отрезка s) не зависит от возраста и в среднем равно 2,1, и может быть приблизительно вычислено по формуле orel = s/2,1. На примере группы 64 пациентов, взятых из той же когорты обследованных, (от 21 до 88 лет), разделенной на 4 возрастные подгруппы в соответствии с классификацией ВОЗ, показано, что относительный вертикальный размер позвоночника, уменьшается с возрастом. Разница средних относительных значений вертикального размера позвоночника в первой и в четвертой возрастной подгруппе составила 3,75 óрела. Также продемонстрирован относительный вклад каждого отдела позвоночника в это уменьшение.</p></sec><sec><title>Заключение</title><p>Заключение. Предлагаемая относительная единица измерения “óрел” может быть использована в качестве универсальной меры длины, независимой от масштаба и способа получения рентгеновского изображения для измерения и сравнения структур позвоночника у взрослых в любом возрасте.</p></sec></abstract><trans-abstract xml:lang="en"><p>The paper proposes a method for using the relative values of linear dimensions for spine structures, which are necessary to compare the results obtained from digital and conventional radiographs having different scales.</p><sec><title>The purpose of the study</title><p>The purpose of the study: to develop a method for quantifying the spine structures of adult patients in relative units of measurement.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Using digital spine radiographs of 141 patients (from 21 to 88 years old), with careful observance of the same magnification, it is shown that the metric length of the segment tangent to the image of the vertebral body CI lower contour – the órel standard – has no age trend.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The ratio of segment tangent to the image of sacrum upper contour (segment s) and órel standard dimension also does not depend on age and is on average equal to 2.1. So the segment can be approximately calculated as órel = s/2.1. A group of 64 patients, from 21 to 88 years old, taken from the general cohort is divided into four age subgroups according to the WHO classification. It is shown that relative vertical spine size decreases with age. The difference in average relative vertical spine size for the first and the fourth age subgroups was 3.75 órels. The relative contribution of each spine part to the decrease is also demonstrated.</p></sec><sec><title>Conclusion</title><p>Conclusion. The proposed relative unit of measurement “órel” can be used as a universal measure of length, independent of the scale and method of obtaining an X-ray image for measuring and comparing the structures of the spine in adults at any age.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>позвоночник</kwd><kwd>рентгенография</kwd><kwd>эталон óрел</kwd><kwd>уменьшение высоты позвоночника при старении</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spine</kwd><kwd>radiography</kwd><kwd>“órel” dimensional segment</kwd><kwd>spine reduction with aging</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">• O’Brien M.F., Kuklo T.R., Blanke K.M., Lenke L.G., Radiographic Measurement Manual Spinal Deformity Study Group, Medtronic Sofamor Danek, USA, Inc. 2008, 110 pp.</mixed-citation><mixed-citation xml:lang="en">• O’Brien M.F., Kuklo T.R., Blanke K.M., Lenke L.G., Radiographic Measurement Manual Spinal Deformity Study Group, Medtronic Sofamor Danek, USA, Inc. 2008, 110 pp.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">• Zdeblick A.T., Albert T.J.
