We present four clinical cases of Schwartz–Jampel syndrome. Principles of diagnostic and results of surgical treatment of the lower limbs deformities are discussed. Importance of this study comprises unique description of rare cases. Surgical treatment for orthopaedic conditions is important and can lead to functional improvement, prevent progression of deformities and enhance daily activity.</p></abstract><trans-abstract xml:lang="ru"><p>Синдром Шварца–Джампела (хондродистрофическая миотония) – моногенное наследственное заболевание, характеризующееся уникальным сочетанием признаков скелетной дисплазии и нейромышечного заболевания. Представлены 4 клинических случая синдрома Шварца–Джампела. Рассмотрены принципы диагностики и опыт хирургического лечения деформаций нижних конечностей. Ввиду того, что в современной научной отечественной литературе имеются единичные описания клинических примеров данного синдрома, настоящие наблюдения имеют большую значимость. Хирургическое лечение деформаций опорно-двигательного аппарата патогенетически обоснованно, так как позволяет добиться функциональных улучшений и опороспособности, предотвратить прогрессирование деформаций и контрактур, увеличивая двигательную активность пациентов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>chondrodystrophic myotonia</kwd><kwd>Schwartz–Jampel syndrome comprehensive diagnostics</kwd><kwd>surgical treatment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хондродистрофическая миотония</kwd><kwd>синдром Шварца–Джампела</kwd><kwd>комплексная диагностика</kwd><kwd>хирургическое лечение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Gusev E.I., Konovalov A.N., Skvorcova V.I. et al.
