Bone fracture could lead to the evidenced swelling due to inflammation. As the bone breaks, it will also tear the surrounding soft tissues, periosteum and vessels. Often a hematoma will from surrounding the fracture ends. The hematoma clots. This loss of blood supply causes death of osteocytes within lacunae of the bone ends. This death may occur as far back as the collateral channels. These dead tissue areas then undergo necrosis. This necrosis stimulates an inflammatory response. Prostaglandins cause vasodilation and leaky vessels. This allows plasma and other fluids to accumulate in the interstitium. This results in acute edema and inflammation. This inflammation is chemotactic for granulocytes and other immuno-modulating cells. This case was presented as an acute onset lameness which points to a possible fracture. The fact that the mare may have stepped on the foal as well as the fact that the foal is a member of a small herd increases the chances that trauma caused this lameness. Because the lameness is localized to only one part of one limb trauma is more likely than infection or a congenital defect which would most likely affect more than one joint (bilateral disease process).
