Fig. 4-19 A 3-month-old domestic
short-haired cat with a right rear
limb lameness, which occurred after
a tape recorder fell on the cat. Pain
was elicited on palpation of the right
hip. On the initial radiographs
obtained at the time of evaluation (A
and B), there is slight malalignment
of the right femoral capital epiphysis
(arrow). Radiographs were obtained
3 days later (C and D). The fracture
line and fracture displacement are
obvious. Diagnosis: Femoral capital
epiphyseal fracture (Salter type I).
