Rafiqul Alam In-Seong Jeong Jong-Il Lee In-Hyuk Choi1 Department of Surgery and Radiology College of Veterinary Medicine Chonbuk National University Jeonju 561-756 Korea 2Royal Animal Medical Center Seoul 131-878 Korea An intact male German shepherd dog 4 y body wt. 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. Key words dog subluxation total hip replacement Canine total hip replacement THR has become well established as an effective method for the treatment of disabling conditions of the hip 6 12 . It is the treatment of choice for re-establishing normal pain-free limb function and joint mechanics in dogs with hip dysplasia and associated osteoarthritis chronic luxation fractures failed femoral head and neck excision and avascular necrosis of the femoral head 1 2 8 . The Richards Canine II THR was the first clinically available hip prosthesis for dogs 13 . Now-a-days Modular Biolox Canine Modular THR System Osteonics USA has become available. The Modular Biolox Total Hip prosthesis consists of three components- a femoral stem femoral head and acetabulum. The femoral stem and femoral head are made of cobalt chrome stainless steel or titanium metal alloy and the acetabulum is made of ultra high molecular weight .
