OSA is a locally invasive neoplasm with a high rate of metastasis, mostly to the lungs. Dueto similarities in biology and treatment of OSA in dogs and humans, canine OSA represents a valid and important tumour model. Differences between canine and human OSAs include the age of occurrence (OSA is most commonly an adolescent disease in humans), localisation (the stifle is the most common site of localisation in humans) and limited use of neoadjuvant chemotherapy in canine OSA.

Several surgical techniques have been used to preserve the limb and they represent a valid alternative to amputation. After surgicalresection of the OSA, the defect may be filled with a frozen corticalallograft (an endoprosthesis ) or with theresected (), autoclaved(or irradiated().
Bone or metallic implants are fixed in position with a bone plateand screws, and arthrodesis of the adjacent joint is performed. Acombination of allograft and prosthesis has been used to preservethe limb for OSA of the proximal femur (Themore common complications associated with cortical allograft,pasteurised autograft and endoprosthesis include local tumourrecurrence (15–28%), infection (31–60%) and implant failure orloosening (11–40%) ().
