The authors retrospectively reviewed RNIITO Arthroplasty Registry data of revision total hip arthroplasties performed in RNIITO in 3 year period (2011-2013). Part of early revisions within 5 years after the index procedure in general revision structure was 33% . Two hundred seventy three (64%) procedures had infection reason, 79 (19%) - aseptic loosening, 35 (8%) - dislocation and 27 (6%) - periprosthetic fractures in reasons of revision, respectively. More than half of revisions were performed within the first year after the index procedure. Early primary revisions after index total hip arthroplasty were performed in 254 (59,8%)cases, and repeated revisions were performed in 171cases one or more times. Of early primary revisions 125(49,2%) patients had index total hip athroplasty in our hospital, and 129 (50,8%) patients had index total hip athroplasty in other hospitals of Russian Federation. Our THA early revision structure is differs significantly from published in literature, moreover there is difference between revision reasons after primary total hip arthroplasty of our hospital and other hospitals. Revision reasons structure doesn’t show rate of primary THA complications, but defines main problems that should be solved.
A purpose of the study was to evaluate the immediate and medium-term outcomes of the treatment of patients with primary tumor lesions of proximal femur after the lesion resection together with total hip arthroplastyby total revision systems. Material and methods. 34 patients with primary tumors of proximal femur [chondrosarcoma - 9 (26.5%),giant cell tumor - II (32.4%),osteosarcoma - 2 (5.8%), other malignancies - 5 (14.7%),benign neoplasms - 7 (20.6%)] underwent the conserving surgery at R.R. Vreden Russian Research Institute of Traumatology and Orthopedics since 2003 through 2013. The follow-up was from one to five years. The age of patients ranged from 16 to 70 years, patients younger than 40 years accounted for 61.8%. Acetabulum was replaced by standard components. To replace post-resection defects of proximal femur, in 21 (61.8%) patents revision legs of cementless fixation Wagner Revision (Zimmer) were used, in 10 (29.4%) - “Fenix”, and in 3 (8.8%) - Solution (DePuy, J&J). Results. A technique of total hip arthroplasty with the use of revision systems demonstrated excellent and positive results in 32 (94.2%) cases. Complications leading to revision surgery occurred in 3 (8.8%) patients. Conclusion. The method allows achievement of favorable functional outcomes and early patients’ activation without worsening the oncologic component of treatment and being not inferior to expensive modular systems.
Реферат Эндопротезирование тазобедренного сустава является одним из самых успешных хирургических вмешательств за всю историю медицины. Однако возрастающая потребность в этих операциях создает значительную нагрузку на национальные системы здравоохранения всего мира, что обусловило возрастающий интерес к экономической стороне этой проблемы. Появление новых конструкций также вносит вклад в удорожание эндопротезирования. Однако всегда ли использование новых и более дорогих имплантатов улучшает клинический результат? Ответ на этот вопрос и является целью нашей работы. Мы изучали в базе MedLine литературу по проблеме влияния на эффективность лечения основных трендов в разработке новых эндопротезов тазобедренного сустава. Кроме того, был произведен анализ данных РнИИТО им. Р.Р. Вредена для сравнения сроков, структуры и частоты использования специальных ревизионных конструкций при первых ревизиях отечественных и импортных эндопротезов. Согласно полученным результатам, новизна и стоимость конструкции не является основным фактором долговременной функциональной службы эндопротеза. Ключевые слова: тотальное эндопротезирование тазобедренного сустава, стоимость эндопротезирования, результаты эндопротезирования.
