Interpretation of juvenile trauma requires understanding of biomechanical and remodeling factors, as well as the dynamics of the growth process. Although terminology relating especially to biomechanical factors can be complex, use of proper terms is essential to avoid misunderstanding. Analysis can include direct observation, individual history documentation, radiography, microscopy, and bone scintigram study. In addition to the appearance of the trauma, relevant observations include the type and area of bone involved, age of the individual, and possible evidence of repair. Such analysis can elucidate the nature of juvenile trauma and facilitate interpretation of the timing of fracture events.
