therefore, the exact reasons for the removal of the sulox head during revision surgery on (b)(6), 2009 remain unknown.The sulox head was combined with a ceramic insert from falcon medical.This combination has not been approved or tested for use and is therefore not a legally marketed product combination.Therefore, it remains unknown if and to what extent this product combination contributed to the reported event.[1] zimmer gmbh.Instruction leaflet for endoprostheses.Art.No.D 011 500 200 - edfispsw - ed.0408.The need for corrective measures is not indicated and zimmer switzerland.Manufacturing gmbh considers this case as closed.Zimmer biomet's reference number of this file is (b)(4).
