Ipsilateralt vaskulariserat ulna autograft vid behandling av osteosarkom i distala radius hos hund : en fallstudie

Sammanfattning: Limb-sparing surgery aims to provide a functional pain free leg for the patient after removal of a local tumour in the leg. Reasons to perform limb-sparing instead of amputation can be arthrosis or hipdysplasia or other problems with the locomotor apparatus that makes the patient unsuitable for amputataion. Owner reluctance to amputate is another reason for limb-sparing. This master's thesis is a case study of a dog with an osteosarcoma in its distal radius. The dog was treated by a limb-sparing method that uses the ipsilateral ulna as a vascularized roll-over autograft. The operation was performed at the Small animal clinic at Sveriges Lantbruks Universitet (SLU). There were only three reported cases of this surgical method before, all in the US. The dog was treated with carboplatin postoperatively as adjuvant treatment. The thesis also includes the preoperative staging and assessment as well as a thorough follow up with scintigraphy and radiography for more than one year postoperatively. The dog retained excellent function of the operated limb and had a good quality of life until it was euthanised 408 days after the limb-spare surgery due to disease unrelated to the osteosarcoma and the limb-spare procedure.
