Radiographic findings in several joints of nine bears

Figure 3. Brown bear, 23 year-old, ventrodorsal flexionview of both hip joints. The
marked bilateral incongruence of the articular contours, subluxation and marked
osteophytic and periarticular reactions are consistent with bilateral osteoarthritic
alterations of the hip joints as a sequale of hip displasia. The changes are comparable
to hip displasia in dogs.
Figure 4. Polar bear, 27 years-old, mediolateral view of the left stifle. Presence of
entesiophytes and osteophytes proximally and distally at the patella, cranially and
caudally at the tibial plateau and caudally at the femoral condyles. The infrapatellar fat
pad is partially dislocated or opacified by a soft tissue structure. A soft tissue opaque
structure is bowing in caudal direction of the femorotibial joint (articular border).
