Erratum to: Ceramic Heads Decrease Metal Release Caused by Head-taper Fretting and Corrosion

Erratum to: Clin Orthop Relat Res (2016) 474:985–994 DOI 10.1007/s11999-015-4683-1

In the study, “Ceramic Heads Decrease Metal Release Caused by Head-taper Fretting and Corrosion” there is an error in the Materials and Methods section regarding the second moment of area. The correct second moment of area is $I=\frac{\mathit{\pi }}{4}{r}^4.$ The sentence should read: “The second moment of area $I=\frac{\mathit{\pi }}{4}{r}^4$ was determined using the radius of the stem cone taper (r) at the distal end where the trunnion exits the bore.”

The authors apologize for the error.

In addition, the last sentence of the first paragraph in the Discussion section is missing a period. The sentence should read: “Visual fretting-corrosion scores were correlated with volumetric material loss.”

We apologize for the error.
