In children with arthrogryposis, a lack of elbow flexion with extensor elbow contractures limits the child’s self-care.</p> <p><bold>Aim.</bold> The aims of this study were to follow and analyze treatment results after posterior arthrolysis of the elbow joint with lengthening (Z-plasty, according to the V-Y technique) or without lengthening the triceps of the shoulder in children with arthrogryposis in different age groups.</p> <p><bold>Materials and methods.</bold> Data from 109 patients with arthrogryposis with extensor contractures in the elbow joints (158 joints) who underwent posterior arthrolysis of the elbow joint to increase passive flexion in the elbow joint from 2005 to 2018 were included in this study. Clinical, and X-ray examination of patients was carried out.</p> <p><bold>Results.</bold> The children were divided into nine groups depending on their age at the time of the operation and the method of surgical correction (with or without lengthening of the triceps muscle). The follow-up period in the postoperative period in the main group of patients (67.1% of cases) was 4.5 years. Good treatment results were observed in 95.83% of children younger than 3 years who did not lengthen the triceps compared with 85.56% of children of the same age who extended the triceps tendon. The amplitude of passive movements after surgery was greatest in children younger than 1 year and was greater with lengthening (104.00° ± 16.24°) than without lengthening (91.38° ± 10.27°) of the triceps tendon (<italic>p</italic> &lt; 0.001). However, in cases where lengthening of the triceps tendon was not performed, extension was less limited. Over 3 years, <italic>m. triceps br.</italic> showed satisfactory results with Z-extension and V-Y extension, increasing to 19.44% and 36.51%, respectively. Results of treatment in children older 7 than years were comparable with those of children 3–7 years old.</p> <p><bold>Conclusions.</bold> In children with arthrogryposis after posterior arthrolysis of the elbow joint, receiving a passive range of motion in the elbow joint allowed the child to use adaptive mechanisms for self-care. The results of treatment with extensor elbow contracture after posterior artrolysis depended not on the elongation technique (V-Y or Z-plasty) but on the angle at which the triceps tendon was sewed, the patient’s age at the time the operation was performed, and the postsurgery rehabilitation of the child.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Отсутствие сгибания в локтевом суставе у детей с артрогрипозом при разгибательных контрактурах значительно ограничивает самообслуживание ребенка.</p> <p><bold>Цель</bold> — оценить результаты лечения разгибательных контрактур локтевых суставов после заднего артролиза локтевого сустава с удлинением (Z-образно, по V-Y-технике) и без удлинения трехглавой мышцы плеча у детей в разных возрастных группах.</p> <p><bold>Материалы и методы.</bold> С 2005 по 2018 г. в ФБГУ «НИДОИ им. Г.И. Турнера» Минздрава России для увеличения пассивного сгибания в локтевом суставе у 109 пациентов с артрогрипозом с разгибательными контрактурами в локтевых суставах (158 суставов) был выполнен задний артролиз. Проводили клиническое и рентгенологическое обследование пациентов.</p> <p><bold>Результаты.</bold> Все дети были разделены на девять групп в зависимости от возраста, в котором была проведена операция, и метода оперативной коррекции (с удлинением и без удлинения трехглавой мышцы плеча). Срок наблюдения большинства пациентов составил 4,5 года. У детей до 3 лет, которым не проводили удлинения трехглавой мышцы, наблюдались хорошие результаты лечения в 95,83 % случаев. У детей того же возраста, которым удлиняли сухожилие трехглавой мышцы, хорошие результаты зафиксированы в 85,56 % случаев. Амплитуда пассивных движений после операции больше всего увеличивалась у детей до 1 года, однако при удлинении сухожилия трехглавой мышцы плеча больше, чем без удлинения (без удлинения <italic>m. triceps br.</italic> — 91,88 ± 10,27°, с Z-образным удлинением <italic>m. triceps br.</italic> — 104,00 ± 16,24°, <italic>p</italic> &lt; 0,001). Разгибание в меньшей степени было ограничено у детей, которым не выполняли удлинения трехглавой мышцы плеча. У детей старше 3 лет при Z-образном удлинении <italic>m. triceps br. </italic>удовлетворительные результаты зарегистрированы в 19,4 % случаев, при V-Y-удлинении <italic>m. triceps br.</italic> — в 36,5 %. Результаты лечения у детей старше 7 лет были сопоставимы с данными детей 3–7 лет.</p> <p><bold>Заключение.</bold> Получение пассивного объема движений в локтевом суставе у детей с артрогрипозом после заднего артролиза позволяло ребенку пользоваться приспособительными механизмами при самообслуживании. При выполнении заднего артролиза локтевого сустава с удлинением трехглавой мышцы результат лечения зависел от угла, при котором сшивали сухожилие трехглавой мышцы плеча (при угле сшивания 150° разгибание было ограничено меньше, чем при угле 100°), возраста пациента, в котором была проведена операция, и реабилитации ребенка после операции.</p></trans-abstract><trans-abstract xml:lang="zh"><p><bold>背景：</bold>关节挛缩患儿缺乏肘部屈曲能力，伴随肘部伸肌挛缩，因此自理能力受限。</p> <p><bold>目的：</bold>本研究旨在分析不同年龄组关节挛缩患儿接受肘关节后侧松解术联合或不联合肱三头肌延长术（Z形或V-Y技术）的治疗效果。</p> <p><bold>材料和方法：</bold>本研究包含了109例关节挛缩伴肘关节（158例关节）伸肌挛缩的患者，这些患者在2005年至2018年接受了膝关节后侧松解术，以增强膝关节的被动屈曲能力。行临床检查、超声检查和X线检查。</p> <p><bold>结果：</bold>根据手术年龄和手术矫正方法（联合或不联合肱三头肌延长术），将患儿分为九组。主要研究组（67.1%）术后随访期为4.5年。3岁以下的患儿中，与接受肱三头肌肌腱延长术的患儿（85.56%）相比，95.83%未肱三头肌延长术的患儿取得了良好疗效。1岁以下患儿在术后的被动运动幅度最大，而肱三头肌肌腱延长（104.00°± 16.24°）病例的术后被动运动幅度超过未行肱三头肌肌腱延长术的病例（91.38°± 10.27°）（p &lt; 0.001）。但未行肱三头肌肌腱延长术的患儿伸展能力受限。3年间，肱三头肌Z形伸展和V-Y伸展疗效尚可，分别增加至19.44%和36.51%。7岁以上患儿的治疗效果与3~7岁患儿相当。</p> <p><bold>结论：</bold>接受肘关节后侧松解术后，膝关节被动活动度使关节挛缩患儿能够通过适应性机制照顾自己。后侧关节松解术后膝关节伸肌挛缩的治疗效果不是取决于延长技术（V-Y或Z形），而是取决于肱三头肌肌腱的缝合角度、手术时间和术后康复情况。</p></trans-abstract><kwd-group xml:lang="en"><kwd>arthrogryposis</kwd><kwd>contracture</kwd><kwd>elbow</kwd><kwd>posterior сapsulotomy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>артрогрипоз</kwd><kwd>контрактура</kwd><kwd>локтевой сустав</kwd><kwd>задняя капсулотомия</kwd></kwd-group><kwd-group xml:lang="zh"><kwd>关节挛缩</kwd><kwd>挛缩</kwd><kwd>肘部</kwd><kwd>后侧关节囊切开术。</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="en">State task</institution></institution-wrap><institution-wrap><institution xml:lang="ru">Государственное задание</institution></institution-wrap></funding-source><award-id></award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Агранович О.E., Баиндурашвили А.Г., Петрова Е.В., и др.
