(A) The regions of bone with the largest microdamage sites were identified (32 per specimen). Subsequently, regions of bone without microdamage were selected at random (32 per specimen). (B) The bone surface around each region was displayed without showing microdamage so that the observer was blinded to the presence of microdamage. A cavity was identified as an indentation on the bone surface in the three-dimensional image. (C) The presence of a resorption cavity was confirmed by observing the eroded surface (arrows) in multiple cross-sections.
