This concerns the magnitude of cervical lordosis in the norm and in juvenile kyphosis in both pre- and postoperative periods, as well as the relationship of these changes with the spinopelvic parameters. There is almost no information on the correlation between the state of cervical lordosis and the development of proximal transitional kyphosis.</p> <p><bold><italic>Aim of the study.</italic></bold> To determine the features of the cervical spine in patients with Scheuermann’s disease in the pre- and postoperative periods by analyzing the literature data.</p> <p><bold><italic>Results. </italic></bold>The literature data do not allow us to clearly define the limits of normal in the quantitative assessment of cervical lordosis. The only thing all researchers agree on is that the cervical lordosis should be considered discretely, namely at the C1-C2 and C2-C7 levels. The most commonly used parameters of the cervical-thoracic junction are T1 slope, thoracic inlet angle (TIA) and position of the sagittal vertical axis (SVA).</p> <p>The magnitude of cervical lordosis in Scheuermann’s disease varies from 4° to 35°, i.e., thoracic kyphosis increase is not always accompanied by the development of compensatory cervical hyperlordosis. In thoracic deformities (the apex is at the level of T10 and cranial), the magnitude of cervical lordosis is significantly greater than that in thoracolumbar deformities (the apex is at the level of T11 and caudal). In the first case, the cervical lordosis (C2-C7) is 19.4-26.2°, while in the second one — 4.7-8.5°.</p> <p>Very few literature data demonstrate that in terms of cervical lordosis dynamics, patients with Scheuermann’s disease do not represent a homogeneous group. The only pattern is that the cervical lordosis increases slightly in the long–term postoperative period. The spinopelvic parameters in patients with Scheuermann’s disease differ little from the normal ones and almost do not change after corrective interventions. We could not find any publications attempting to relate the risk of PJK to cervical-thoracic junction parameters (T1, TIA, SVA).</p> <p><bold><italic>Conclusion.</italic></bold> The state of the cervical spine in patients with severe forms of Scheuermann’s disease, subject to surgical correction, has not been studied enough. This concerns the magnitude of cervical lordosis, its dynamics in the postoperative period, its relationship with spinopelvic parameters, as well as the correlation between parameters of transitional cervical-thoracic spine and development of proximal transitional kyphoses. Further studies of this problem are needed.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Актуальность.</italic></bold> Состояние шейного отдела позвоночника у пациентов с болезнью Шойермана на настоящий момент изучено недостаточно. Это касается величины шейного лордоза в норме и при ювенильных кифозах как в до-, так и в послеоперационном периодах, а также связи этих изменений с позвоночно-тазовыми параметрами, Практически нет информации о корреляции состояния шейного лордоза с развитием проксимальных переходных кифозов.</p> <p><bold><italic>Цель публикации </italic></bold>— на основании анализа литературы определить особенности состояния шейного отдела позвоночника у пациентов с болезнью Шойермана в до- и послеоперационном периодах.</p> <p><bold><italic>Результаты.</italic></bold> Данные литературы не позволяют четко очертить границы нормы при количественной оценке шейного лордоза. Единственное, в чем сходятся все исследователи, — шейный лордоз следует рассматривать дискретно, а именно — на уровнях С1–С2 и С2–С7. Наиболее часто используемыми параметрами шейно-грудного перехода являются наклон Th1 позвонка, наклон входа в грудную клетку (TIA) и положение сагиттальной вертикальной оси (SVA). Величина шейного лордоза при болезни Шойермана варьирует от 4° до 35°, т.е. увеличение грудного кифоза далеко не всегда сопровождается развитием компенсаторного шейного гиперлордоза. При грудных деформациях (вершина на уровне Т10 и краниальнее) величина шейного лордоза значительно превышает таковую при грудо-поясничных деформациях (вершина на уровне Т11 и каудальнее). В первом случае шейный лордоз (С2–С7) составляет 19,4–26,2°, во втором — 4,7–8,5°. Весьма немногочисленные литературные данные демонстрируют, что в аспекте динамики шейного лордоза пациенты с болезнью Шойермана — это не гомогенная группа, и единственная закономерность заключается в том, что в отдаленном послеоперационном периоде шейный лордоз незначительно увеличивается. Позвоночно-тазовые параметры у пациентов с болезнью Шойермана мало отличаются от нормальных показателей и практически не меняются после корригирующих вмешательств. Не удалось найти работ, в которых предпринята попытка увязать риск развития проксимального переходного кифоза с параметрами шейно-грудного перехода (Th1, TIA, SVA).</p> <p><bold><italic>Заключение</italic></bold>. Состояние шейного отдела позвоночника у пациентов с тяжелыми формами болезни Шойермана, подлежащими оперативной коррекции, изучено недостаточно. Это касается величины шейного лордоза, его динамики в послеоперационном периоде, связи с позвоночно-тазовыми параметрами, а также взаимозависимости параметров переходного шейно-грудного отдела с развитием проксимальных переходных кифозов. Необходимы новые исследования в этом направлении.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>Scheuermann’s disease</kwd><kwd>cervical spine</kwd><kwd>cervical lordosis</kwd><kwd>juvenile kyphosis</kwd><kwd>surgical treatment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>болезнь Шойермана</kwd><kwd>шейный отдел позвоночника</kwd><kwd>шейный лордоз</kwd><kwd>ювенильный кифоз</kwd><kwd>хирургическое лечение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Scheuermann H.W.
