OBJECTIVE: To report the clinical application of a hemipelvic and proximal femoral endoprosthesis for limb salvage.

STUDY DESIGN: Retrospective case report.

ANIMAL: One 5-year-old, neutered female, flat coated retriever with a malignant neoplasia of the left coxofemoral joint.

Category: Hip - Oncology

OBJECTIVE: To report modification of the endoprosthesis surgical limb-salvage technique to treat a locally extensive osteosarcoma in a dog and associated functional outcome.

STUDY DESIGN: Clinical case report.

ANIMALS: One client-owned dog.

Objective: To report modification of the endoprosthesis surgical limb‐salvage technique to treat a locally extensive osteosarcoma in a dog and associated functional outcome.

Study design: Clinical case report.

Animals: One client‐owned dog.

OBJECTIVE: To report modification of the endoprosthesis surgical limb-salvage technique to treat a locally extensive osteosarcoma in a dog and associated functional outcome.

STUDY DESIGN: Clinical case report.

ANIMALS: One client-owned dog.

OBJECTIVE: To critically evaluate whether open fracture fixation is a significant risk factor for latent osteosarcoma development.

STUDY DESIGN: Case-control study.

SAMPLE POPULATION: Dogs undergoing open fracture repair and dogs diagnosed with osteosarcoma.

OBJECTIVE: To describe the surgical technique for ischiectomy in the dog and to report the procedure in a case.

STUDY DESIGN: Case report.

ANIMAL: An 11-year-old spayed female mixed breed dog with chondrosarcoma of the ischium.

METHODS: The dog presented for hindlimb lameness and evaluation after a radiographic finding of a lytic lesion confined to the left ischium. Following staging and confirmation of stage 1 disease, an ischiectomy with preservation of the hindlimb was performed.

ANIMALS: 64 client-owned dogs.

Category: Oncology

OBJECTIVE: To evaluate clinical characteristics, outcome, and prognostic variables in a cohort of dogs surviving > 1 year after an initial diagnosis ofosteosarcoma.

Objective-To evaluate clinical characteristics, outcome, and prognostic variables in a cohort of dogs surviving > 1 year after an initial diagnosis ofosteosarcoma. Design-Retrospective case series. Animals-90 client-owned dogs. Procedures-Medical records for an 11-year period from 1997 through 2008 were reviewed, and patients with appendicular osteosarcoma that lived > 1 year after initial histopathologic diagnosis were studied. Variables including signalment, weight, serum alkaline phosphatase activity, tumor location, surgery, and adjuvant therapies were recorded.

Objective-To describe the biological behavior, clinical outcome, and prognostic factors of osteosarcoma of the maxilla, mandible, or calvarium in dogs. Design-Retrospective case series. Animals-183 client-owned dogs with osteosarcoma of the maxilla, mandible, or calvarium. Procedures-Medical records for dogs treated for osteosarcoma of the maxilla, mandible, or calvarium from 1986 through 2012 were reviewed. Dogs with a histopathologic diagnosis of osteosarcoma and treated for a primary tumor arising from these bones of the head were included.
