Backgrоund. In most cases, haematogenic osteomyelitis affects the long bones of the skeleton. Predominantly, the centers of destruction are located in the lower extremities. The orthopedic complications of haematogenic osteomyelitis were observed (according to different data) in 22%71.2% of childhood cases. In 16.2%53.7% of cases, the complications can lead to childhood (nascent) disability. Aim. The purpose of the research is to conduct a retrospective analysis of femoral deformity correction results in children with haematogenic osteomyelitis consequences by applying both an Ortho-SUV Frame (based on passive computer navigation) and following the Ilizarov method. Materials and methods. The study examined 76 patients of both genders aged between 8 and 17 years old who were experiencing the consequences of haematogenic osteomyelitis in the long bones of the lower extremities. A comparative assessment of the parameters reflecting the effectiveness of circular external fixation in combination with an Ortho-SUV Frame and the Ilizarov method was conducted. Reference lines and angles before and after surgery, elongation size, distraction time, deformity correction period, external fixation index, number of complications, and the functional result were all considered. Results. All the children underwent deformity correction surgery, and the length of the afflicted lower extremity segment was reconstructed (restored). The use of the repositioning unit enabled a higher correction accuracy (94.45%) of the femur in comparison with the Ilizarov frame (30%). The frequency of excellent functional results in the first group of patients was more than 1.5 times higher than in the second group, whereas the satisfactory results turned out to be almost twice as low. Fewer complications were observed while using the Ortho-SUV hexapod. Conclusions. The application of the Ortho-SUV Frame at the long-bone-deformity-correction stage facilitates an increase in the efficiency of the circular external fixation method.
Введение. Врожденная контрактура подвздошно-большеберцового тракта -достаточно редкая патология, вызывающая трудности диагностики и планирования лечебных мероприятий. Отсутствие четкого представ-ления о причинах заболевания вызывает разногласия в трактовке диагноза у пациентов с данной патологией. В русскоязычной литературе это заболевание обозначается как идиопатическая разгибательно-отводящая кон-трактура тазобедренного сустава или идиопатическая контрактура большой ягодичной мышцы, врожденная контрактура сухожилий больших ягодичных мышц. В англоязычной литературе чаще говорится о врожденной или идиопатической контрактуре больших ягодичных мышц. Клиническое наблюдение. Представлен результат лечения ребенка 6 лет с врожденной контрактурой под-вздошно-большеберцового тракта. На хромоту было обращено внимание с началом его ходьбы, но правиль-ный диагноз не был установлен. В клинической картине, наряду с ограничением приведения и разгибания в тазобедренном суставе, уплотнением мягких тканей по наружной поверхности правого бедра в виде лампаса, имелись перекос таза, укорочение правой нижней конечности и вальгусная деформация диафиза правой бе-дренной кости. Ультрасонография и магнитно-резонансная томография показали наличие фиброзного тяжа по наружной поверхности правого бедра. Фиброзный тяж иссечен на протяжении 15 см, выполнен временный гемиэпифизеодез медиальной порции дистальной зоны роста правой бедренной кости. Результаты и обсуждение. При контрольном обследовании через 1 год пациент жалоб не предъявлял. Реци-дива контрактуры не отмечено. По данным рентгенологического исследования достигнута коррекция валь-гусной деформации правой бедренной кости, металлические конструкции из которой удалены. Несмотря на чаще встречающуюся разгибательно-отводящую направленность контрактуры подвздошно-большеберцового тракта, на что указывают большинство авторов, направленность и выраженность ее, по-видимому, может за-висеть от преобладающей зоны фиброзного перерождения мышечных групп. И при преобладающем пораже-нии большой ягодичной мышцы можно ожидать более выраженный разгибательный компонент, в то время как при преобладающем поражении мышцы, напрягающей широкую фасцию бедра, -сгибательный. Что мы и наблюдали у нашего пациента.Ключевые слова: дети; врожденный; контрактура; подвздошно-большеберцовый тракт.
Background. Мeningococcal infection with damage to various organs and systems, including the musculoskeletal system, causes growth plate dysfunction, which usually leads to the formation of orthopedic consequences, including axis deviation and/or limb length discrepancy. Aim. This study aimed to analyze the features of limb deformities and methods for their correction in children with consequences of meningococcemia. Materials and methods. The retrospective analysis was performed on patients with consequences of meningococcemia who were examined and surgically treated in the clinic between 2012 and 2018. A total of 12 patients (six boys and six girls) were included, with an age range of 215 years. The examination included clinical, X-ray, and physiological methods. Treatment methods consisted of a combination of angular deformity correction and limb lengthening. Results. In 12 patients, 76 growth plate arrests of long bones were found. Most frequently (17.1%), growth plate arrests of the distal femur and proximal tibia were observed, which resulted in limb shortening and/or axis deviation. For restoration of limb alignment in 10 (83.3%) patients, transosseous compression-distraction osteosynthesis was performed. For limb deformity correction, guided growth technique was applied by using eight-plate for temporary epiphysiodesis of active functioning part of the growth plate in four (33.3%) patients, whereas partial growth plate arrest resection with following epiphysiodesis was achieved in two (16.6%). Conclusions. Meningococcal septicemia leads to long bone growth plate dysfunction. The main complaints in this patient are limb shortening and their deformity. Along with the transosseous compression-distraction osteosynthesis technique, using the guided growth method by carrying out temporary epiphysiodesis of the remaining functioning part of the growth plate of damaged bone was appropriate.
