Three series of experiments performed in 18 puppies. Counter-directed transphyseal reinforcement of tibia performed in Series I,, transphyseal reinforcement combined with transverse osteotomy of leg bones — in Series II, transphyseal elastic osteosynthesis and subperiosteal positioning the titanium nickelide mesh with intervolved in it elastic rods during transverse leg bone osteotomy performed in Series III.</p><p><bold>Results:</bold> Transphyseal reinforcement resulted in growth retardation of the operated tibia. The loss of residual growth was 3.8 mm (p =0.078) in series I; 7.8 mm (p =0.032) — in series II; 7.7 mm (p =0.042) — in series III. Eccentric insertion of transphyseal rods formed an angular deformity (mean value 7°; p =0.023) of the distal tibial epiphysis in the process of residual growth. Periosteal and endosteal reactions contributed to enlargement of diaphyseal diameter of 3.9 mm (series II; p =0.037) and 3.8 mm (series III; p =0.041). Any difference of diameter between operated and intact tibia was not observed in series I.</p><p><bold>Conclusion:</bold> Intramedullary transphyseal reinforcement retards longitudinal bone growth. The positioning of the telescopic systems should be as close as possible to the center of growth plates in order to prevent angular deformities. Subperiosteal reinforcement doesn’t retard consolidation of fragments, and it can be combined with intramedullary transphyseal osteosynthesis</p></abstract><trans-abstract xml:lang="ru"><p>Интрамедуллярный трансфизарный эластичный остеосинтез применяется у детей при заболеваниях, сопровождающихся сниженными прочностными свойствами костной ткани, в первую очередь при несовершенном остеогенезе.</p><p><bold>Цель исследования:</bold> изучить рост большеберцовой кости в условиях трансфизарного встречного проведения эластичных стержней без нарушения целостности кости, при моделировании поперечного перелома, а также сочетании трансфизарного армирования и поднадкостничного расположения титановой сетки с вплетенными в нее эластичными стержнями.</p><p><bold>Методы:</bold> проведено нерандомизированное контролируемое исследование на 3 группах (сериях) щенков (по 6 животных в каждой серии). В серии I производили встречное трансфизарное армирование большеберцовой кости, в серии II — трансфизарное армирование в сочетании с поперечной остеотомией костей голени, в серии III трансфизарный эластичный остеосинтез выполнялся вместе с поднадкостничным введением сетки из никелида титана с вплетенными в нее эластичными стержнями при поперечной остеотомии костей голени.</p><p><bold>Результаты:</bold> трансфизарное армирование вызывало замедление роста оперированной большеберцовой кости с потерей длины на 3,8 мм (p =0,078) в I, на 7,8 мм (p =0,032) во II и на 7,7 мм (p =0,042) в III серии. Эксцентричное проведение трансфизарных стержней формировало угловую деформацию в процессе последующего роста, в среднем на 7° (p =0,023) на уровне дистального эпифиза во всех сериях. Пери- и эндостальные реакции способствовали увеличению диаметра диа- физа большеберцовой кости в серии II на 3,9 мм (p =0,037), в серии III — на 3,8 мм (p =0,041) по сравнению с контрольной конечностью. В первой серии разницы диаметров между оперированной и интактной большеберцовой костью не наблюдалось.</p><p><bold>Заключение:</bold> интрамедуллярное трансфизарное армирование замедляет рост кости в длину. Для предотвращения угловых деформаций расположение телескопических систем должно быть максимально близким к центру ростковых зон. Поднадкостничное армирование не замедляет консолидацию фрагментов и может сочетаться с интрамедуллярным трансфизарным остеосинтезом.</p></trans-abstract><kwd-group xml:lang="en"><kwd>transphyseal elastic osteosynthesis</kwd><kwd>osteogenesis imperfecta</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>трансфизарный эластичный остеосинтез</kwd><kwd>несовершенный остеогенез</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Н.В.Попкова</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
