Clinical evaluation of canine acetabular fractures stabilized with an acetabular plate.

A retrospective study of 14 dogs with one or more acetabular fractures stabilized with an acetabular plate was conducted. Twelve of the 14 dogs had additional orthopedic injuries. Follow-up was longer than 6 months. Eleven dogs were evaluated by assessment of radiographs, lameness, mid-thigh circumference, coxofemoral joint range of motion, crepitus, and pain. Varying degrees of osteoarthrosis were noted radiographically at follow-up. Ten of 12 dogs examined had occasional or no clinical lameness. In 10 of 12 dogs, mid-thigh circumference was less on the limb that sustained the acetabular fracture. Nonunion was diagnosed in one plated acetabulum in which two screws had broken. A return to normal or nearly normal function was observed when there were no more than two orthopedic injuries.
