Resumo
Background: Osteosarcoma (OSA) is the most common primary bone tumor of the appendicular skeleton of dogs. Itmainly affects the metaphyseal region of long bones in large and giant breed dogs.The markedly aggressive and metastaticcharacter of the disease leads to an invariably poor to unfavorable prognosis.Although amputation is commonly performed,different surgical techniques may be used to preserve the limb. The most common methods of limb preserving surgeriesinvolve the use of endoprosthesis and allogeneic or autologous grafts. This report describes the successful use of total hipreplacement to treat a 3-year-old male dog, with OSA in the femoral head and neck.Case: This report describes the successful use of total hip replacement to treat a 3-year-old male dog, with OSA in thefemoral head and neck. The OSA stage IA located in the femoral head and neck was resected and treated through thelimb-sparing. The bone defect and joint function was reconstructed with total hip arthroplasty technique using a cementlesship prosthesis. The result of the histopathological analysis of the excised bone tissue showed a minimally productiveosteoblastic osteosarcoma. To date, the patient shows satisfactory movement rate and motion range, with no pain to palpationand without lameness in that limb. The radiographic follow-up after 24 months showed no local recurrence, metastasispulmonary or complications related to the implant. Total hip arthroplasty resulted in safe recovery of orthopedic signsassociated with osteosarcoma of the femoral head and neck [...](AU)
