Однако ограничение движений в суставе приводит к изменению биомеханики стопы, перегрузке смежных суставов и сопровождается снижением активности, что особенно актуально для молодых пациентов. Предлагаемые на рынке суставозамещающие импланты первого плюснефалангового сустава имеют ряд недостатков, что послужило причиной разработки оригинальной модели гемиэндопротеза первого плюснефалангового сустава.</p><p>Цель работы — демонстрация оригинальной модели гемиэндопротеза первого плюснефалангового сустава и способа его установки для лечения пациентов с hallux rigidus 3–4 стадии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Гемиэндопротез выполнен из циркониевой керамики. Головка гемиэндопротеза изготовлена с низким профилем. Ножка импланта в сечении имеет четырёхлопастную форму, что обеспечивает ротационную стабильность гемиэндопротеза. Установку гемиэндопротеза производят с  помощью специально разработанного инструментария. Представлен клинический случай лечения пациента 74 лет с диагнозом: «Остеоартрит первого плюснефалангового сустава 3 стадии».</p></sec><sec><title>Результаты</title><p>Результаты. Анкетирование пациента до и через 24 месяца после лечения: AOFAS Hallux — 28 и 95 баллов, ВАШ — 9 и 0 баллов, FFI — 112 и 6 баллов соответственно. Объём движений в суставе (разгибание/ сгибание) в предоперационном периоде составил 0°–0°–5°, через 24 мес. — 60°–0°–15°. Результаты динамической педобарографии позволяют сделать вывод о восстановлении физиологического распределения давления в стопе в послеоперационном периоде.</p></sec><sec><title>Обсуждение</title><p>Обсуждение. Первые предложенные варианты суставозамещающих имплантов первого плюснефалангового сустава представлены моделями тотальных эндопротезов из силикона и металлических сплавов. Однако при их установке возникает необходимость резекции значительного количества костной ткани, описаны случаи нестабильности компонентов эндопротеза. Более щадящим является метод гемиэндопротезирования данного сустава. Однако использование имплантов из металлических сплавов проявляется агрессивным воздействием на противоположную суставную поверхность. Гемиэндопротезирование первого плюснефалангового сустава имплантом из циркониевой керамики позволяет минимизировать риск возникновения этих осложнений.</p></sec><sec><title>Заключение</title><p>Заключение. Гемиэндопротезирование первого плюснефалангового сустава с использованием импланта из циркониевой керамики оригинальной модели показало эффективность при лечении пациентов с hallux rigidus 3–4 стадии. Продемонстрированная методика является хорошей альтернативой артродезу данного сустава.</p></sec></abstract><trans-abstract xml:lang="en"><p>Introduction Arthrodesis is the “gold standard” for the treatment of stage 3–4 osteoarthritis of  the  first metatarsophalangeal (MTP) joint. However, restricted movements in the joint can lead to changes in the biomechanics of the foot overloading the adjacent joints and are accompanied by decreased activity which is important for younger patients. The available implants of the first MTP joint have some disadvantages and an original hemiarthroplasty of the first MTP joint was developed.</p><p>The objective was to demonstrate an original technique of hemiarthroplasty of the first MTP joint and installation to treat stage 3–4 hallux rigidus.</p><p>Material and methods The hemiendoprosthesis is made of zirconium ceramics. The head of the hemiendoprosthesis is made with a low profile. The cross-section of the stem has a four-bladed shape to ensure rotational stability of the implant. The hemiendoprosthesis can be placed using specially designed instruments. A case of a 74-year-old patient diagnosed with stage 3 osteoarthritis of the first MTP joint is reported.</p><p>Results AOFAS Hallux scored 28 and 95, VAS scored 9 and 0 and FFI scored 112 and 6 preoperatively and at  24  months, respectively. The range of motion in the joint (extension/flexion) measured 0°–0°–5° preoperatively and 60°–0°–15° at 24 months. The dynamic pedobarography indicated to the physiological distribution of pressure in the foot being restored postoperatively.</p><p>Discussion The first implants offered to replace first MTP joint were made of silicone and metal alloys and total joint arthroplasty was associated with significant resection of bone tissue; cases of endoprosthetic instability were reported. Hemiarthroplasty appeared to be a sparing technique. However, implants made of metal alloys could have an aggressive effect on the opposite articular surface. Hemiarthroplasty of the first MTP joint using a zirconium ceramic implant could minimize the risk of the complications.</p><p>Conclusion Hemiarthroplasty of the first MTP joint using an original zirconium ceramic implant was shown to be effective for patients with stage 3–4 hallux rigidus. The technique reported can be a good alternative to arthrodesis of MTP joint.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>остеоартрит</kwd><kwd>hallux rigidus</kwd><kwd>гемиэндопротезирование</kwd><kwd>циркониевая керамика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>osteoarthritis</kwd><kwd>rigid finger</kwd><kwd>hemiarthroplasty</kwd><kwd>zirconium ceramics</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">Hoveidaei AH, Roshanshad A, Vosoughi AR.
