Therefore, they are more susceptible to the development of pathological conditions of joints, which often present a specific clinical picture.</p> <p><bold>The aim<italic> </italic></bold>is to demonstrate a rare structural damage to the hip joint capsule and iliofemoral ligament in a ballet dancer.</p> <p><bold>Case description<italic>.</italic></bold> The patient is a 32-year-old professional ballet dancer. She noted pain and limited range of motion in the right hip joint during her dance classes. Radiologic examination methods identified minimal anatomical features characteristic of femoroacetabular impingement, and damages to the acetabular labrum and structures of the anterior joint capsule. Pain and functional status were assessed using the VAS, HOOS, iHOT-12 questionnaires before surgery and at 6, 12, 18, 24, 36 and 48 months postoperatively. During the surgery, correction of bone deformity of the hip joint and all identified soft-tissue damages was successfully carried out. After 5 months, the patient returned to her professional activities. According to the VAS score, pain decreased from 6 points to 0 at the follow-up time points. At the same time a periodic slight aching pain after physical activities remained. During the follow-up, the functional status was assessed as excellent according to the HOOS and iHOT-12 questionnaires. However, the patient noted slight limitations in the range of motion when performing some professional exercises.</p> <p><bold>Conclusions<italic>.</italic></bold> The presented clinical case demonstrates that patients with hip pain whose professional activity is associated with extreme hip range of motion require special attention during clinical provocative tests and critical evaluation of effective measurements when compared with the reference values of radiologic examination methods. In the present case, arthroscopic correction of structural damages made it possible to achieve excellent functional results through the planning and performance of surgical intervention taking into account the concept of microinstability.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность<italic>. </italic></bold>Артисты балета обладают морфологическими особенностями строения тазобедренных суставов, что обусловлено их профессиональной деятельностью. Ввиду этого они более подвержены развитию патологических состояний суставов, и нередко им присуща специфическая клиническая картина.</p> <p><bold>Цель</bold> — демонстрация редкого повреждения суставной капсулы тазобедренного сустава и подвздошно-бедренной связки на примере клинического наблюдения артиста балета.</p> <p><bold>Описание случая<italic>.</italic></bold> Пациентка — профессиональная балерина 32 лет. Во время занятий танцами отмечала боль и ограничение амплитуды движения в правом тазобедренном суставе. Лучевыми методами исследований были выявлены минимальные анатомические особенности, характерные для фемороацетабулярного импинджмента, а также повреждения суставной губы вертлужной впадины и структур передней суставной капсулы. Оценка боли и функционального состояния оценивались с помощью шкал-опросников ВАШ, HOOS, iHOT-12 до операции и через 6, 12, 18, 24, 36, 48 мес. Во время операции была успешно проведена коррекция костных основ тазобедренного сустава и всех выявленных мягкотканных повреждений. Уже через 5 мес. пациентка возобновила профессиональную деятельность. Болевой синдром по ВАШ снизился с 6 баллов до 0 в контрольных точках, но периодически возникала легкая ноющая боль после физических нагрузок. В течение всего периода наблюдения функциональное состояние по HOOS и iHOT-12 оценивали как отличное, однако при выполнении некоторых профессиональных упражнений присутствуют небольшие ограничения в амплитуде движения.</p> <p><bold>Заключение<italic>.</italic></bold> Представленный клинический случай демонстрирует, что пациенты, имеющие боль в области тазобедренного сустава, чья деятельность сопряжена с экстремально высокой амплитудой движений бедра, требуют особого внимания при проведении провоцирующих тестов клинического обследования и критической оценки результативных измерений при сопоставлении с референтными значениями лучевых методов диагностики. Артроскопическая коррекция структурных повреждений в описываемом случае позволила достигнуть высоких функциональных результатов благодаря планированию и реализации хирургического вмешательства с учетом концепции микронестабильности.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>hip arthroscopy</kwd><kwd>microinstability</kwd><kwd>joint capsule</kwd><kwd>acetabular labrum tears</kwd><kwd>femoroacetabular impingement</kwd><kwd>ballet dancers</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>артроскопия тазобедренного сустава</kwd><kwd>микронестабильность</kwd><kwd>суставная капсула</kwd><kwd>повреждение губы вертлужной впадины</kwd><kwd>фемороацетабулярный импинджмент</kwd><kwd>артисты балета</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Singh Y., Pettit M., El-Hakeem O., Elwood R., Norrish A., Audenaert A. et al.
