Понимание биомеханики движений в позвоночно-тазовом сегменте играет важную роль в успешном лечении пациентов с hip-spine синдромом. Анализ биомеханических процессов, происходящих в биокинематической цепи позвоночник–таз–бедро, возникающих при переходе из положения стоя в положение сидя, позволяет сделать вывод, что ацетабулярная ось вращения таза в пространстве не является единственной. Классические способы измерения показателей PI, PT, overhang S1 применимы для положения пациентов стоя и используют в качестве отправной точки тазобедренный сустав, так как он является точкой вращения таза в пространстве в стоячем положении. Ранее мы посредством математического моделирования описали пространственные изменения таза при данной смене положения тела и показали наличие второй точки вращения таза в пространстве, появляющейся в положении сидя. Мы предположили, что в положении сидя при расчете показателей позвоночно-тазовых взаимоотношений необходимо использовать другие методы их определения.</p><p>Цель работы — оценить параметры сагиттального баланса предложенным альтернативным способом у пациентов в положении стоя и сидя.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проанализирована медицинская документация и результаты рентгенологического обследования 20 пациентов с односторонним идиопатическим коксартрозом, которым выполнена операция тотального эндопротезирования тазобедренного сустава. Рассчитаны рентгенологические параметры: PI, PT, Overhang S1 в положении стоя и сидя, антенаклон ацетабулярного компонента эндопротеза, предложены и рассчитаны параметры PI седалищный, PT седалищный, отклонение седалищных бугров в положении стоя и сидя.</p></sec><sec><title>Результаты</title><p>Результаты. В исследовании показано отсутствие статистической разницы значений углов PI стандартный для положения стоя и PI седалищный для положения сидя, что соответствуют объективным данным и является общепринятым. Также приведены примеры изменения рентгенологических параметров наклона крестца и отклонения седалищных бугров, отражающих вращение таза в пространстве через вторую, седалищную, ось, что является подтверждением наличия двух осей вращения таза в зависимости от положения тела.</p></sec><sec><title>Обсуждение</title><p>Обсуждение. Проведенные расчёты продемонстрировали возможности использования альтернативных показателей позвоночно-тазовых взаимоотношений (PT седалищный, расстояние нависания крестца (overhang S1), отклонение седалищных бугров), позволяющие оценить пространственную трансформацию таза и возможность прогнозирования пространственного положения ацетабулярной впадины, что является важным фактором, влияющим на успех лечения пациентов с сочетанной патологией тазобедренного сустава и позвоночника.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные нами данные дополняют версию о двухосевой концепции вращения таза. Предложен альтернативный способ измерения параметров сагиттального баланса в положении сидя. Для оценки практической значимости данного метода требуются дальнейшие исследования.</p></sec></abstract><trans-abstract xml:lang="en"><p>Introduction The understanding of the biomechanics of movements in the spinopelvic segment plays an important role in the successful treatment of patients with hip-spine syndrome. Analysis of the biomechanical processes occurring in the biokinematic chain of the spine–pelvis–hip during the transition from standing position to sitting position allows us to conclude that the acetabular axis of rotation of the pelvis in space is not the only one. Classical methods for measuring PI, PT, overhang S1 are applicable for patients in a standing position and use the hip joint as a starting point, since it is the point of rotation of the pelvis in space in a standing position. Previously, using mathematical modeling, we described spatial changes in the pelvis during a given change in the body position and showed the presence of a second point of pelvis rotation in space, which appears in a sitting position. We assumed that in a sitting position, it is necessary to use other methods for calculating indicators of spinopelvic relationships for their determination.</p><p>Purpose of the study was to evaluate the parameters of patients’ sagittal balance using the proposed alternative method in standing and sitting positions.</p><p>Materials and methods Medical documentation and the results of X-ray examination of 20 patients with unilateral idiopathic coxarthrosis who underwent total hip replacement surgery were analyzed. The radiographic parameters were calculated: PI, PT, overhang S1 in standing and sitting positions, anterior inclination of the acetabular component; parameters PI ischial, PT ischial, deviation of the ischial tuberosities in standing and sitting positions were proposed and calculated.</p><p>Results The study shows that there is no statistical difference in the values of the angles PI standard for a standing position and PI ischial for a sitting position. It corresponds to objective data and is generally accepted. Examples of changes in radiographic parameters of the sacral slope and the deviation of the ischial tuberosities were shown reflecting the rotation of the pelvis in space through the second, ischial axis, that confirm the biaxial concept of pelvic rotation.</p><p>Discussion The calculations demonstrated the possibility of using alternative indicators of spinopelvic relationships (PT, distance of overhang of the sacrum (overhang S1), deviation of the ischial tuberosities). They enabled assessment of the spatial transformation of the pelvis and the ability to predict the spatial position of the acetabulum, which is an important factor for successful treatment of patients with combined pathology of the hip joint and spine.</p><p>Conclusion Our findings complement the biaxial concept of pelvic rotation. An alternative method for measuring sagittal balance parameters in a sitting position has been proposed. Further research is required to assess the practical significance of this method.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>позвоночник</kwd><kwd>суставы нижних конечностей</kwd><kwd>позвоночно-тазовые взаимоотношения</kwd><kwd>ориентация</kwd><kwd>параметры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spine</kwd><kwd>hip joint</kwd><kwd>lower extremity</kwd><kwd>spinopelvic relationship</kwd><kwd>orientation</kwd><kwd>parameters</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">Молодов М.А., Даниляк В.В., Ключевский В.В. и др.
