Aggressive piecemeal excision and cervical bridging fixation for cervical vertebral osteosarcoma in two dogs and two cats

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.

Cervical spine reconstruction after total vertebrectomy using customized three-dimensional-printed implants in dogs

“…Aggressive vertebral tumor resection, such as total vertebrectomy, has been suggested as necessary for better prognosis and prevention of pathological fractures [ 6 15 ]. Spine reconstruction in previous veterinary cases has limitations, such as insufficient contact area and poor fit [ 7 8 9 ].…”

“…In humans, there have been several papers on the aggressive resection and reconstruction of cervical vertebral tumors for a better prognosis [ 12 13 14 ]. The recent veterinary report also suggested the necessity of aggressive resection, even in cervical vertebral tumors achieving local control to prevent pathologic fracture, improve clinical symptoms, and prolong life expectancy [ 15 ].…”
