The cross-sectional area of calluses at the site of failure were determined using image analysis software after mechanical testing in control wild-type (dark) and bp (light) fractured and nonfractured contralateral controls. The cross-sectional area was consistently greater in fractured bones as compared with nonfractured contralateral controls at all times with the exception of bp samples at Day 56. Control fracture calluses were consistently larger than bp fracture calluses at Days 10, 14, 21, and 28.
