Comparison of synovial fluid, urine, and serum ion levels in metal-on-metal total hip arthroplasty at a minimum follow-up of 18 years

摘要: Diagnosis of adverse reactions to metal debris in metal-on-metal hip arthroplasty is a multifactorial process. Systemic ion levels are just one factor the evaluation and should not be relied upon solely determine need for revision surgery. Furthermore, correlation between cobalt or chromium serum, urine, synovial fluid local tissue still incompletely understood. The hypothesis was that elevated serum urine metal-ion concentrations associated with primary total arthroplasties (THA) failure articulations long-term. In our present study, we evaluated these 105 cementless THA articulating surfaces small head diameter at minimum 18 years postoperatively. Spearman showed high joint aspirate concentration (r = 0.81) level 0.77) patients as only source metal-ions. analysis valuable method screening. more than renal insufficiency additional investigations, like aspirations an important tool wear THA.
