Cervical Spine in Scheuermann’s Disease: Review

Background. The state of the cervical spine in patients with Scheuermanns disease has still not been studied enough. This concerns magnitude lordosis norm and juvenile kyphosis both pre- postoperative periods, as well relationship these changes spinopelvic parameters. There is almost no information on correlation between development proximal transitional kyphosis.
 Aim study. To determine features periods by analyzing literature data.
 Results. data do allow us to clearly define limits normal quantitative assessment lordosis. only thing all researchers agree that should be considered discretely, namely at C1-C2 C2-C7 levels. most commonly used parameters cervical-thoracic junction are T1 slope, thoracic inlet angle (TIA) position sagittal vertical axis (SVA).
 varies from 4 35, i.e., increase always accompanied compensatory hyperlordosis. In deformities (the apex level T10 cranial), significantly greater than thoracolumbar T11 caudal). first case, (C2-C7) 19.4-26.2, while second one 4.7-8.5.
 Very few demonstrate terms dynamics, represent a homogeneous group. pattern increases slightly longterm period. differ little ones change after corrective interventions. We could find any publications attempting relate risk PJK (T1, TIA, SVA).
 Conclusion. severe forms disease, subject surgical correction, lordosis, its dynamics period, parameters, kyphoses. Further studies this problem needed.
