- W2978754931 abstract "Non-union and persistence of infection at a fracture site for long periods are always described as a challenge to orthopedists, especially in cases of severe compound fractures with comminution and segmental bone loss. This is a case series of septic non-unions, using S53P4 bioactive glass for adjunctive treatment, using internal syntheses or external fixators. The objective is to retrospectively evaluate the results of the use of S53P4 bioglass for the adjunctive treatment of septic non-unions.We reviewed 18 patients with septic non-unions. The patients were preoperatively classified using the Non-union Scoring System (NUSS) and union outcomes were assessed by the modified radiographic union scale in tibial (RUST) fractures. Of the 18 patients treated, six underwent internal osteosynthesis and 12 were treated with external fixators in combination with bioactive glass grafting.The patients had a mean NUSS score of 56.6 (standard deviation of 7.6) and fracture union was achieved according to the RUST score in 17 of 18 cases (94.4%), with a mean value of 10.2 (standard deviation of 1.0). One patient was lost to follow-up. Reevaluation using the modified RUST score was 12.3 (SD = 1.0), maintaining union of 17/18.The fracture union rate was high, according to the literature, as was control of infection. Level of Evidence IV, Case series.A não união e a persistência de infecção no local de uma fratura por períodos prolongados são sempre descritas como desafios para os ortopedistas, especialmente em casos de fraturas expostas graves, com cominuição e perdas de segmentos ósseos. Esta é uma série de casos de não consolidações infectadas, utilizando o vidro bioativo S53P4 como adjuvante no tratamento, utilizando-se sínteses internas ou fixadores externos. O objetivo é avaliar retrospectivamente os resultados do uso do biovidro S53P4 como adjuvante no tratamento de não uniões infectadas.Foram revistos 18 pacientes com não consolidações infectadas. Os pacientes foram classificados antes da cirurgia pelo Non-Union Severity Score (NUSS), e os resultados quanto à consolidação foram avaliados pelo escore de RUST modificado (escala radiográfica de consolidação da tíbia). Dos 18 pacientes tratados, seis foram submetidos à osteossíntese interna e 12 foram tratados com fixadores externos, associados à enxertia com vidro bioativo.Os pacientes tinham resultado NUSS médio de 56,6 (desvio padrão de 7,6) e a consolidação foi obtida segundo o escore de RUST em 17 de 18 casos (94,4%), com valor médio de 10,2 (desvio padrão de 1.0). Um paciente abandonou o seguimento. A reavaliação pelo escore de RUST modificado foi de 12,3 (PF=1,0), mantendo a consolidação de 17/18.O índice de consolidação foi elevado, segundo a literatura, bem como controle infeccioso. Nível de evidência IV, série de casos." @default.
