At the same time, a growing number of operations entail an increase in the number of reinterventions.</p> <p><bold>The aim of the study</bold> — to determine the causes and evaluate the outcomes of revision interventions for proximal interphalangeal joint arthroplasty based on the data from a federal center for trauma and orthopedics.</p> <p><bold>Methods<italic>. </italic></bold>We analyzed gender and age distribution of patients, the number of revisions, possible causes of implant failure, its localization and type, survival rate of the construct, surgical approaches. The study covers a 15-year period.</p> <p><bold>Results<italic>. </italic></bold>Among 95 performed primary PIPJ arthroplasties, 15 (15.8%) cases of failure were observed in 14 patients. There was 1 periprosthetic fracture; 2 cases of implant fracture; instability of implant components — 12 cases associated with injury, increased physical activity and other causative factors. The maximum failure rate was detected in the II finger (31.6% of the number of initially implanted prostheses). After primary arthroplasty, instability was most often observed in hinged implants (SBI D.G.T. PIP joint implant and the RM Finger Mathys). The option for reintervention in 2 (16.7%) cases was PIPJ arthrodesis, in 11 (83.3%) — revision arthroplasty.</p> <p><bold>Conclusions<italic>. </italic></bold>Despite the significant (15.8%) rate of adverse outcomes after proximal interphalangeal joint arthroplasty, most frequently caused by implant instability, the survival rate of the implants reaches up to 10 years in some cases and depends both on the type of prosthesis and the patient’s occupation. Overall, revision proximal interphalangeal joint arthroplasty allows for joint mobility preservation and statistically significantly reduces pain.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность<italic>. </italic></bold>В последние десятилетия в мире значительно возросло количество выполненных первичных операций эндопротезирования проксимального межфалангового сустава, что повлекло за собой увеличение числа ревизионных вмешательств.</p> <p><bold>Цель исследования</bold> — определить причины и оценить результаты ревизионных вмешательств после эндопротезирования проксимального межфалангового сустава кисти на примере федерального травматолого-ортопедического центра.</p> <p><bold>Материал и методы<italic>.</italic></bold> Проведен анализ половозрастного состава пациентов, количества ревизионных операций, возможных причин несостоятельности эндопротеза, его локализации и типа, срока службы конструкции, хирургических подходов. Глубина исследования — 15 лет.</p> <p><bold>Результаты<italic>. </italic></bold>Среди 95 выполненных операций первичного эндопротезирования проксимального межфалангового сустава выявлено 15 (15,8%) случаев неблагополучных исходов у 14 пациентов. Зарегистрированы один перипротезный перелом; 2 случая перелома имплантата; 12 случаев нестабильности компонентов, связанных с травмой, повышенной физической нагрузкой и другими причинными факторами. Максимальная частота неудач выявлена на II пальце (31,6% от числа первично установленных эндопротезов). После первичного эндопротезирования нестабильность чаще всего выявлялась после установки связанных эндопротезов (SBI D.G.T. PIP joint implant и RM Finger Mathys). Вариантом повторного вмешательства в двух (16,7%) случаях явился артродез проксимального межфалангового сустава, в 11 (83,3%) — ревизионное эндопротезирование.</p> <p><bold>Заключение<italic>.</italic></bold> Неблагополучные исходы составляют значительную долю (15,8%) первичного эндопротезирования проксимального межфалангового сустава. Наиболее частой причиной является нестабильность эндопротеза. В то же время срок службы конструкций достигает в ряде случаев 10 лет и зависит, вероятно, и от типа эндопротеза, и от рода занятий пациента. Ревизионное эндопротезирование проксимального межфалангового сустава позволяет сохранить подвижность сустава, статистически значимо уменьшая интенсивность болевого синдрома.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>proximal interphalangeal joint</kwd><kwd>implant failure</kwd><kwd>instability</kwd><kwd>revision arthroplasty</kwd><kwd>proximal interphalangeal joint arthrodesis</kwd><kwd>periprosthetic fracture</kwd><kwd>implant fracture</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>проксимальный межфаланговый сустав</kwd><kwd>несостоятельность эндопротеза</kwd><kwd>нестабильность</kwd><kwd>ревизионное эндопротезирование</kwd><kwd>артродез проксимального межфалангового сустава</kwd><kwd>перипротезный перелом</kwd><kwd>перелом имплантата</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Котельников Г.П., Колсанов А.В., Николаенко А.Н., Згирский Д.О., Дороганов С.О.
