An immunocompromised patient with a history of multiple hip implant revisions extended courses of empiric antibiotic treatment, and a retained metallic rod in the femoral medullary canal was transferred for diagnostic studies and treatment. A high suspicion of fungal infection and utilization of extended and specific fungal cultures were the diagnostic keys for infection with Trichosporon inkin. The treatment consisted in a debridement surgery with the use of a functional spacer with cement supplemented with voriconazole and vancomycin plus a 6-month systemic treatment with voriconazole. After 2 years of follow-up, the patient is free of symptoms.
Objective: the management of septic metaphyseal nonunions is challenging, with inconsistent outcomes. Antibiotic cement-coated implants have been demonstrated good outcome for diaphyseal infected nonunions, however there is no data in metaphyseal infected nonunions. Methods: fifteen adult patients with septic metaphyseal nonunions of the femur or tibia were treated with antibiotic cement-coated plates. The antibiotic cement-coated plate was prepared with either gentamicin or vancomycin. Outcome measures were infection control, bone healing, return to pre-injury level on daily activities, and quality of life at the last follow-up visit. A p value of <5% was considered significant. Results: Methicillin-susceptible S. aureus was isolated in 53.3% cases. Average postoperative follow-up time was 18 months. Local infection control and radiographic bone healing were adequately achieved in 93.3% patients. No patient presented recurrent symptoms of surgical site infection. Fourteen patients reported to be either able, or on the same level as before injury, with 73.3% reporting no problems in all five dimensions of the EQ-5D-3L. Persistent infection was the only variable associated with a reduced long-term quality of life. Conclusion: antibiotic cement-coated plate is a viable and efficient surgical technique for the definitive management of juxta-articular metaphyseal septic nonunions of the femur and tibia.
RESUMO Introdução: implantes revestidos de cimento com antibiótico vêm demonstrando bons resultados no tratamento da pseudoartrose infectada da diáfise, no entanto seu uso na metáfise dos ossos longos ainda é pouco explorado. Neste estudo relatamos uma série de casos de pseudoartrose infectada da metáfise do fêmur e da tíbia tratados com o uso de placas revestidas de cimento com antibiótico. Métodos: Os antibióticos usados foram gentamicina e/ou vancomicina. Os desfechos analisados na última visita ambulatorial foram controle de infecção, consolidação óssea, retorno às atividades diárias e qualidade de vida. Regressão linear bivariada foi usada para avaliar fatores individuais que afetaram a qualidade de vida dos pacientes. Um valor p<5% foi considerado estatisticamente significativo. Resultados: quinze pacientes adultos foram incluídos no estudo. S. aureus suscetível à meticilina foi isolado em 53,3% dos casos. O tempo médio de acompanhamento pós-operatório foi de 18 meses. Controle local da infecção e consolidação óssea radiográfica foram alcançados em 93,3% dos pacientes. Nenhum paciente apresentou sintomas recorrentes de infecção de sítio cirúrgico. Quatorze pacientes relataram ser capazes, mas não no nível pré-lesional ou no mesmo nível de antes da lesão, com 73,3% relatando nenhum problema em todas as cinco dimensões do EQ-5D-3L. Infecção persistente foi a única variável associada à redução da qualidade de vida a longo prazo. Conclusão: A placa revestida de cimento com antibiótico mostrou-se uma técnica cirúrgica viável e eficiente para o tratamento da pseudoartrose infectada da metáfise do fêmur e da tíbia.
