Pathological focus was localized in the epiphysis and metaepiphysis of long bone predominantly. Clinical manifestations were pain syndrome, restriction of movement and development of contracture in the adjacent joint. Typical radiological signs included excentrically located osteolytic locus of destruction with speckled inclusions and clear contour. The locus was separated by sclerosis line and periostal stratums were present in the distance from the locus. CT, MRT and angiographic examination enabled to determine the destructive locus at early stages of its development and to differentiate with other tumors, inflammatory diseases and dystrophic processes. In all cases diagnosis was verified morphologically. All patients underwent surgery. In the majority of cases periarticular subchondral resection with cavity electrocoagulation and alloplasty of the defect was performed. In case of articular cartilage destruction intracapsular marginal or segmental resection followed by allo- or autoplasty of the defect was carried out. Recurrences were observed in 8,2%) of cases. In 8 patients shortening or deformity of limb developed as a result of growth zone damaged caused by pathological process and surgical intervention. Those problems were eliminated by additional surgery.</p> <p> </p></abstract><trans-abstract xml:lang="ru"><p>Впервые в отечественной литературе описаны клиника, диагностика и результаты хирургического лечения хондробластомы кости у детей (85 пациентов в возрасте от 8 до 16 лет). Патологический очаг локализовался преимущественно в эпифизе и метаэпифизе длинных костей. В клинической картине преобладали болевой синдром, ограничение движений и формирование контрактуры в близлежащем суставе. Характерными рентгенологическими признаками являлись эксцентрически расположенный остеолитический очаг деструкции с крапчатыми включениями и четкими контурами, отграниченный полоской склероза, наличие периостальных наслоений в отдалении от очага. Обследование с применением компьютерной, магнитно-резонансной томографии и ангиографии позволяло не только выявить очаг деструкции на ранних стадиях развития, но и достаточно эффективно провести дифференциальную диагностику с другими опухолями, воспалительными заболеваниями и дистрофическими процессами. Во всех случаях диагноз верифицирован морфологически. Всем больным проведено хирургическое лечение. В большинстве случаев выполнялась околосуставная субхондральная резекция с электрокоагуляцией полости и аллопластикой дефекта. При разрушении суставного хряща производилась внутрисуставная краевая или сегментарная резекция с последующей алло- или аутопластикой дефекта. В 8,2% случаев наблюдались рецидивы заболевания. У 8 пациентов в связи с разрушением ростковой зоны опухолевым процессом и самим хирургическим вмешательством развились укорочение, деформации конечностей, которые были устранены дополнительным хирургическим пособием.</p></trans-abstract><kwd-group xml:lang="en"><kwd>epiphyseal chondroblastoma</kwd><kwd>tumor of the bones of the skeleton</kwd><kwd>X-ray method of examination</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эпифизарная хондробластома</kwd><kwd>опухоль костей скелета</kwd><kwd>лучевой метод обследования</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Верченко Г.Н. //Актуальные вопросы детской травматологии и ортопедии: Материалы науч.-практ. конф, детских ортопедов-травматологов России. — СПб, 2000. — С. 214-215.</mixed-citation></ref><ref id="B2"><label>2.</label><mixed-citation>Виноградова Т.П.
