RangerRanger’s Story
Ranger is an eight and a half year old Golden Retriever who was diagnosed with a bone tumor. It was in an unusual location involving the right ulna, which in dogs is a non-weight bearing bone. The radius in the front limbs bears most, if not all, of the weight. Because of this, Ranger did not have to undergo a forelimb amputation. Instead, he had an ulnar ostectomy which allowed us to remove just the affected bone. Biopsy was diagnostic for hemangiosarcoma. This tumor arises from blood vessels and is mostly seen affecting the spleen and heart. Ranger is doing well since surgery and just received his third dose of chemotherapy in hopes of delaying disease recurrence for as long as possible.

The middle of Ranger's ulna is less bright in this radiograph due to disease in the bone.

In the post-operative radiograph, Ranger's ulna is removed to prevent the spread of cancer. You can also see little circles near where the bone used to be. These are implantable beads that deliver medicine to the area.
