Long bone failure after intraosseous regional perfusion

Abstract

A 5-year-old Australian Stock Horse gelding was initially referred to the Charles Sturt University Veterinary Clinical Centre (CSUVCC) for assessment of a penetrating laceration over the medial splint bone (second metacarpal bone) of the left foreleg. Clinical examination failed to reveal a communication with a synovial structure, but radiographs showed a palisading bone reaction on the proximal aspect of the medial splint bone which was thought to be a characteristic of infection. Soft tissue swelling precluded access to a peripheral vein, so a decision was made to use intraosseous regional limb perfusion. This was achieved through an access portal in the lateral diaphysis of the third meta..
