Free proximal cortical ulnar autograft for the treatment of distal radial osteosarcoma in a dog.

This report describes the use of a non-vascularized proximal cortical autograft from the ipsilateral ulna in limb-sparing surgery for the treatment of distal radial osteosarcoma. A pancarpal arthrodesis was performed to stabilize the site. Construct failure and probable local tumor recurrence were observed.
