Total hip replacement in a dog.

An intact male German shepherd dog (4 y, body wt. 35.5 kg) was referred to the Animal Medical Center, Chonbuk National University with severe lameness, pain and gait abnormality on the right hind limb. Survey radiographs of the pelvis revealed dysplasia of the right coxofemoral joint with subluxation. The dog was surgically treated performing total hip replacement (THR) using Modular Biolox Canine Modular THR System. The dog began to bear weight and slowly returned to a normal exercise pattern 2 months after surgery. THR resulted in satisfactory clinical functions with 6 months follow up and no complications were observed. Canine modular THR could be a successful modality for the management of disabling conditions of the coxofemoral joint.
