Reemplazo total de cadera en pacientes menores de 45 años, de mayor complejidad respecto al realizado en pacientes mayores de 60 años. Estudio comparativo

Abstract

IntroductionIt has been considered that hip replacement in young adults is associated with lower morbidity due to their age. This study addresses this question by comparing the prevalence of adverse events between two cohorts of patients under 45 years and over 60 years old, who underwent hip replacement surgery at the Instituto de Ortopedia Infantil Roosevelt (IOIR). Materials and methodsA cross-sectional study was performed; two cohorts were established and compared for the purpose of the study: patients younger than 45 years (young adults) and patients over 60 years (conventional adults). Patients in both cohorts underwent to a total hip replacement in the IOIR between 2007 and 2014. ResultsMultiple variables were analyzed according to clinical safety protocols. Among these, duration of the procedure was found to be longer (p<0.001) and average intraoperative bleeding to be higher (p=0.002) in young patients. The most prevalent complication was length discrepancy (p=0.029), also in young adults. DiscussionYoung early hip osteoarthritis is secondary to several severe pathologies, and is always related to deformities, rigidity, discrepancies and previous scars at the hip and surrounding soft tissue structures. Accordingly, young patient's hip arthroplasty implies greater difficulty for the surgeon and increased resources for the health system. Level of evidenceIII.
