Plain-English summary
A 12-year-old Labrador Retriever was brought in for straining to defecate due to a large mass in the pelvic area. After a CT scan confirmed the mass was a high-grade chondrosarcoma (a type of bone cancer), the veterinarians performed a novel surgery to remove part of the pelvis while keeping the dog's hind legs intact. The dog recovered well and was able to walk again within nine days. Four months later, the dog showed no pain or straining, although there was a slight abnormality in its left hind leg.

Abstract
Surgical management of chondrosarcoma with hemipelvectomy is well described, but there have been no reports on extensive excision involving bilateral pubis and unilateral ischium. This report describes a novel pelvectomy technique for the treatment of chondrosarcoma in a large-breed dog. A 12-year-old Labrador Retriever presented for tenesmus due to a large, intra-pelvic mass which was confirmed on computed tomography (CT). Surgery involved removal of the entire left ischium and both pubic bones with preservation of both hind limbs. Histopathology confirmed the diagnosis of a high-grade chondrosarcoma with tumour-free margins of less than 3 mm. The dog recovered well following surgery and regained ambulation within 9 days. Four months postoperatively, the dog had no ongoing pain or tenesmus and only a mild gait abnormality in the left hind limb. Pelvectomy involving the entire pubis and unilateral ischium was well tolerated in a large-breed dog. This technique may offer a novel surgical option to treat neoplasia previously considered too extensive for complete excision.
