“…According to the Lenke classification, types 1 and 5 are optimal for anterior correction. 1 Namely, rigid anterior scoliosis correction has a number of significant advantages compared to posterior interventions: it allows to reduce the number of instrumented segments, 15 allows for correction comparable to posterior instrumentation, 16 , 17 , 18 , 19 diminishes the risks of neurological complications, 20 , 21 as well as the rate of complications associated with wound healing. 19 Additionally, female patients experience less difficulties during pregnancy and childbirth (pregnancy proceeds as in healthy individuals) 22 and the long-term outcomes have proven to be excellent (more than 15 years follow-up).…”

“…Деформация грудного отдела позвоночника -распространенное заболевание, встречающееся у 60 % пациентов с идиопатическим сколиозом [4,9,11]. В современной хирургии сколиоза традиционно используется дорсальный полисегментарный инструментарий третьего поколения, с помощью которого можно осуществлять коррекцию деформации во фронтальной, сагит-тальной и аксиальной плоскостях [5,6,[10][11][12]14].…”

Objective. Comparative analysis of treatment outcomes in patients with idiopathic scoliosis in the thoracic spine using anterior and posterior segmental instrumentation. Material and Methods. The study included 56 patients aged 12 to 18 years with Lenke type 1 scoliotic deformity in the thoracic spine. Correction with anterior instrumentation was performed in 36 cases and with posterior -in 20. Results. The mean value of deformity correction in patients with anterior instrumentation was 81.1 %. Physiological sagittal contour was formed in all patients after surgery. The mean value of deformity correction in patients with posterior instrumentation was 52.5 %. After surgery the magnitude of the primary curve was 32.2° (range, 30-42°), of the compensatory curve -12.4° and at long-term follow-up it comprised 13.3°. Conclusion.Efficacy of anterior correction is comparable with results of posterior segmental instrumentation. Correction of the thoracic scoliosis using anterior instrumentation is the equivalent method of choice for surgical treatment of idiopathic scoliosis.

Objective To compare the rotational stability of fusion constructs using bisegmental fixation of Th12-L2 vertebrae with anterior stabilization or pedicle screw fixation.Material and Methods The strength, rigidity and limit of elasticity in the “injured vertebral motion segments (VMS) – bisegmental anterior stabilization” system under dislocating rotational loads were estimated. The data obtained were compared with the similar characteristics of the “injured VMS – bisegmental 4-screw transpedicular metal construction” system and intact spine segments.Results Under rotational loads the limits of elasticity of injured spine segments of Th12-L2 with anterior stabilization and transpedicular screw fixation (TSF) is 45.5 and 41.7%, respectively, and the general strength is 66.4% and 80%, respectively, as compared with those intact VMS. Rigidity parameters of anterior-stabilized and pedicle screw fixated VMS with unstable damage of L1 are 60.2 and 93.9%, accordingly, in comparison with those intact VMS.Conclusion No significant differences were observed between bisegmental anterior stabilization and bisegmental pedicle screw fixation of thoracolumbar junction in terms of the key mechanical properties. When treating patients with unstable thoracolumbar spine injuries using bisegmental anterior stabilization or transpedicular fixation with 4-screw spinal system possible rotation motion amplitude of operated segments must not exceed 50% of maximum physiological limits.
