Одной из причин отсутствия унифицированных подходов к лечению травматических повреждений позвоночника на уровне поясничного отдела и переходной грудопоясничной зоны является недостаток информации о вкладе различных факторов в стабильность транспедикулярной фиксации.</p></sec><sec><title>Цель</title><p>Цель. Оценить факторы, влияющие на стабильность транспедикулярной фиксации у пациентов с нестабильными травматическими повреждениями поясничного отдела позвоночника и грудопоясничного перехода.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Исследование является ретроспективным, изучены результаты хирургического лечения 192 пациентов с травматическими повреждениями типа А3, А4, В1, В2 и С на уровне поясничного отдела позвоночника и грудопоясничного перехода. Транспедикулярная фиксация использовалась или изолированно, или в сочетании с реконструкцией передней колонны. По показаниям выполнялась передняя или задняя декомпрессия спинного мозга или его корешков. Регистрировались случаи с нарушением стабильности транспедикулярного фиксатора. Использовался логистический регрессионный анализ для оценки прогностической значимости предполагаемых факторов риска.</p></sec><sec><title>Результаты</title><p>Результаты. Частота осложнения увеличивалась при снижении радиоденсивности костной ткани, при экстенсивной резекции костных структур и связок задней опорной колонны, люмбосакральной фиксации и остаточной кифотической деформации. При реконструкции передней колонны и промежуточной фиксации частота осложнения уменьшалась, в то время как передняя декомпрессия и протяженность фиксации не влияли на частоту осложнения.</p></sec><sec><title>Заключение</title><p>Заключение. Дестабилизацию транспедикулярных систем чаще всего связывают с нарушением качества костной ткани, однако хирургическая тактика также может существенно влиять на частоту осложнения, что необходимо учитывать при планировании оперативного вмешательства. Промежуточная фиксация и реконструкция передней колонны в равной степени снижают частоту осложнений. При рисках развития нестабильности фиксатора передняя декомпрессия предпочтительна, поскольку она не влияет на стабильность транспедикулярного фиксатора.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. One of the reasons for the lack of standardized approaches to treating lumbar and thoracolumbar spine traumatic injuries is inconclusive information on relative contribution of various factors to pedicle screw fixation stability.</p></sec><sec><title>Objective</title><p>Objective. To determine risk factors that influence pedicle screw fixation stability in patients with unstable traumatic injuries of a lumbar spine and thoracolumbar junction.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. This was a retrospective evaluation of 192 spinal instrumentations. Patients with type А3, A4, B1, B2 and C injuries of lumbar and thoracolumbar spine were enrolled. Pedicle screw fixation was used either as a stand-alone technique or in combination with anterior column reconstruction. If required, decompression of nerve roots and spinal cord was performed. Cases with pedicle screw fixation failure were registered. Logistic regression analysis was used to assess predictive significance of potential risk factors. </p></sec><sec><title>Results</title><p>Results. Complication rate growth was associated with a decrease in bone radiodensity, posterior decompression extensiveness, lumbosacral fixation and residual kyphotic deformity. Anterior column reconstruction and additional pedicle screw installation led to a decline in complication rate while anterior decompression and fixation length did not influence fixation stability. </p></sec><sec><title>Conclusion</title><p>Conclusion. In most cases, pedicle screw fixation system failure is associated with altered bone quality; however, surgical approach may also impact complication rate and should be taken into account when planning surgical intervention. Anterior column reconstruction and additional pedicle screw installation are associated with the decline in complication rate; the influence of those options is comparable. Anterior decompression does not influence pedicle screw fixation stability; consequently, it is preferable in cases with considerable risk of pedicle screw fixation failure.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>транспедикулярная фиксация</kwd><kwd>реконструкция передней колонны</kwd><kwd>передняя декомпрессия</kwd><kwd>ламинэктомия</kwd><kwd>радиоденсивность</kwd><kwd>травма поясничного отдела позвоночника и грудопоясничного перехода</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pedicle screw fixation</kwd><kwd>anterior column reconstruction</kwd><kwd>anterior decompression</kwd><kwd>laminectomy</kwd><kwd>radiodensity</kwd><kwd>lumbar and thoracolumbar spine injury</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">Melton LJ, Kallmes DF.
