CHAPTER 10 III The Wing: Fracture Healing and Nonhealing 105
A B
C D
Figure 10-11 • A, Close and ultraclose (B) emphasized ventrodorsal views of subacute, minimally displaced fractures of the distal radial
metaphysis and associated ulnar body. The radial break is partially folded on itself, resulting in an abnormally angular appearance, and the
faint ulnar fracture spirals upwardly from the distal metaphysis to the central third of the diaphysis. One-month progress examination
shows close (C) and ultraclose (D) ventrodorsal views of the same area of the wing and the ulnar fracture heavily encased in a lengthy
bony callus and somewhat resembling osteomyelitis. The radial fracture shows no signs of healing; instead, it appears extensively lysed,
presumably a result of a combination of avascular necrosis and posttraumatic osteoporosis.
