Title：Aggressive piecemeal excision and cervical bridging fixation for cervical vertebral osteosarcoma in two dogs and two cats
作成者：獣医師　高野重徳

Abstract：
Two dogs and two cats were referred for primary osteosarcoma of the cervical vertebrae. Each case was treated surgically with a combination of aggressive tumour resection and bridging fixation of the vertebrae, which was performed cranial and caudal to the affected site, using metal implants and polymethylmethacrylate. The cervical spines were stabilised by spinal reconstruction, and the tumours were extensively removed. Aggressive resection and spinal reconstruction prevented pathological fractures, contributed to spinal cord injury recovery, improved clinical symptoms and prolonged life expectancy.

犬2頭、猫2頭が頸椎に発生した原発性骨肉腫のため来院した。各症例は、積極的な腫瘍切除を実施し、金属性インプラントと骨セメントを用いて頸椎を架橋固定することで外科的に治療された。頸椎は脊椎再建により安定化され、腫瘍は広範囲に切除された。積極的な腫瘍切除と脊椎再建によって、病的骨折の防止と臨床症状の改善がもたらされ、生命予後が延長したと示唆された。
