Core tip: Metal ions, derived from Metal-on-Metal (MoM) hip replacements have been a subject of interest since the catastrophic failure of this bearing surface. However, debris generation is not solely limited to the articulating surface, but can arise from the interface between the head and neck at the trunnion. Furthermore, it appears that the phenomenon of ‘trunnionosis’ is not limited to only MoM prosthesis, but to all modular designs and may therefore contribute to the problem of metallosis.
