“…Весьма немногочисленные данные литературы демонстрируют, что в аспекте динамики шейного лордоза пациенты с болезнью Шойермана -это не гомогенная группа, и единственная закономерность (если о таковой вообще можно говорить) заключается в том, что в отдаленном послеоперационном периоде шейный лордоз незначительно увеличивается. При этом данные некоторых авторов свидетельствуют о том, что позвоноч-нотазовые параметры у пациентов с болезнью Шойермана мало отличаются от нормальных показателей и практически не меняются после корригирующих вмешательств [13,14,15,31,32,33,34,35]. Нам не удалось найти работы, авторы которых предприняли попытку увязать риск развития PJK с параметрами шейно-грудного перехода (наклон Th1, TIA, SVA), что вызывает удивление, учитывая актуальность проблемы переходных кифозов.…”

The purpose of the publication. Analysis of literature data concerning the state of the cervical spine in patients with Sheuerman's disease in the pre- and postoperative periods. Literature data. The literature data do not make it possible to clearly delineate the boundaries of the norm when quantifying cervical lordosis. The only thing that all researchers agree on is that cervical lordosis should be considered discretely, namely, at levels C1-2 and C2-7. The most commonly used parameters of the cervical-thoracic junction are the slope of the Th1 vertebra, the thoracic inlet angle (TIA) and the position of the sagittal vertical axis (SVA). The magnitude of cervical lordosis in Sheuermann's disease varies from 4 to 35 , i.e., an increase in thoracic kyphosis 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 significantly exceeds that of thoracolumbar deformities (the apex is at the level of T11 and caudal). In the first case, cervical lordosis (C2-7) is 19.4-26.2, in the second 4.7-8.5. Conclusion. The condition of the cervical spine in patients with severe forms of Sheuermann's disease, subject to surgical correction, has not been studied enough. This concerns the magnitude of cervical lordosis, its dynamics in the postoperative period, the relationship with the vertebral-pelvic parameters, as well as the interdependence of the parameters of the transitional cervical-thoracic region with the development of proximal transitional kyphoses. New research is needed.

ObjectiveThe aim of this study was to investigate the effect of distal fusion level selection on the distal junctional kyphosis (DJK) in Scheuermann kyphosis (SK) patients who underwent posterior fusion.MethodsThirty-nine SK patients who underwent posterior fusion with a minimum follow-up of 3 years were retrospectively evaluated. According to the distal fusion level, patients were divided into 3 groups. Group S; lowest instrumented vertebra (LIV) was the sagittal stable vertebra (SSV), Group F; LIV was the first lordotic vertebra (FLV) and, Group L; LIV was the lower end vertebra (LEV). DJK was evaluated according to distal level selection.ResultsThoracic kyphosis (TK) decreased from 73.3° (SD ± 7.9°) to 39° (SD ± 8.7°) postoperatively, with a mean correction rate of 46% (SD ± 13) (p < 0.0001). In 11 patients, FLV and SSV was the same vertebra. In remaining 28 patients, 10 patients were in Group S, 15 patients were in Group F and 3 patients were in Group L. In Group S, none of them developed DJK, however, DJK was observed 9 of 15 patients in Group F. DJK was developed in all cases in Group L. There is a statistically higher risk for developing DJK when FLV or LEV was selected as LIV (p < 0.05).ConclusionSelecting SSV for the distal fusion level has been found to be effective for preventing DJK. Selecting distal fusion level proximal to SSV will increase the risk of DJK which may become symptomatic and require revision surgery.Level of evidenceLevel IV, therapeutic study.
