CHAPTER 6 III The Wing: Radiography and Normal Radiographic Anatomy 67

Figure 6-3 • Ventrodorsal view of the outspread wings of a nestling owl in Figures 6-1 and 6-2 that shows large lucent gaps in all of the

visible joints, reflecting the transparent nature of the unossified epiphyses. The proximal body of the right ulna is fractured as indicated by

a dense overlap band and slight cortical misalignment (left).

Figure 6-4 • Close-up, ventrodorsal view of the left wing
shows an absence of epiphyseal ossifi cation and
accordingly, large gaps between the bone ends (emphasis
zones) that are characteristic of skeletal immaturity in birds.
