Abstract
Wear and corrosion of taper connections in modular hip
prostheses have gained much attention due to the serious
biological response that can occur due to the metallic debris
originating from this articulation (Pivec et al. 2014). This
has been observed especially for metal-on-metal (MoM)
bearing articulations with large-diameter heads (Gunther
et al. 2013). The biological response is attributed to cobalt
(Co) and chromium (Cr) ions originating from the female
taper interface of the ball head, which is made of CoCr alloy (McGrory et al.
