Head-Neck Taper Corrosion in Hip Arthroplasty

Figure 4

Mechanically assisted crevice corrosion in different scenarios of angular mismatch: (a) head angle, α, greater than neck angle, β; and (b) head angle, α, less than neck angle, β; crevice corrosion can potentially occur in this design due to the corrosive fluid present at the interface.
