The absence of a metal-on-metal bearing does not preclude the formation of a destructive pseudotumor in the hip - A case report

摘要

Sir-Thank you for your interest in our recent case report (Bisseling et al. Acta Orthop 2013; 84 (4): 437-41).You are absolutely right that there is a rather large volume of relatively early literature available, where metal particle and subsequent metal ion release has been described after hip arthroplasties without a metal-on-metal bearing. In fact, this goes beyond hip arthroplasties only and can be relevant to knee arthroplasties, dental implants, plates for fracture care, and so on. For this reason, the additional list of references kindly provided is still incomplete and could fill a single issue of Acta Orthopaedica with references only.One should realize that we only presented an interesting case report and in its current form we provided 25 references, half of which dealt specifically with modular component corrosion, which in our opinion is a lot for a case report already. A complete review of the literature available was clearly beyond the scope of this case report.
