Fracture Dating


Estimation of fracture age should be approached with caution. The current timeline for estimating fracture age ( Table 5.97 ) is based on anecdotal experience of seasoned pediatric radiologists and several small series of children. Although fracture dating is not an inexact science, experienced radiologists should be able to differentiate recent from old fractures separated by weeks or months in time.
