Sobrevida em longo prazo do espaçador cimentado para quadril: Relato de caso Long-Term Survival of Hip Cement Spacer: A Case Report

Resumo Apresentamos um caso único de um homem de 56 anos que deambulou com um espaçador cimentado para quadril durante 11 anos. Após ser submetido a uma hemiartroplastia em virtude de um acidente de carro, o paciente desenvolveu uma infecção articular periprotética (IAP) vários anos depois, sendo submetido à técnica de revisão da etapa 1. Com a resolução da infecção depois da etapa 1, o paciente recusou a segunda etapa, devido à satisfação com o espaçador cimentado por quase 11 anos. Pelo que sabemos, este é o caso mais longo relatado de um espaçador cimentado em um paciente deambulando. Este caso demonstra a confiabilidade mecânica dos espaçadores cimentados reforçados com metal que podem ser mantidos por um prazo longo em pacientes selecionados. Abstract We present a unique case of a 56-year-old male patient who ambulated on a hip cement spacer for 11 years. After hemiarthroplasty after a motor vehicle accident, the patient developed periprosthetic joint infection (PJI) several years later, and underwent stage-1 revision. With the resolution of the infection after stage 1, the patient refused the second stage due to satisfaction with the cement spacer for nearly 11 years. To our knowledge, this is the longest reported case of a cement spacer remaining in an ambulating patient. This case demonstrates the mechanical reliability of metal-reinforced cement spacers, which can remain for long periods in selected patients.
