title: Full-length diaphyseal sequestrum as a consequence of segmental transverse fractures of the large metatarsal bone in a calf.
abstract: A 1-week-old calf was treated for fractured right metatarsus; however, at 3.5 months of age, the fracture site again became unstable. Radiography disclosed segmental transverse metatarsal fractures with an isolated, full-circumference diaphyseal sequestrum. Arteriography and nuclear scintigraphy confirmed the isolation and necrosis of the diaphyseal segment. Diaphyseal sequestra usually develop as cortical or partial circumferential necrotic fragments. The finding of a full-length diaphyseal sequestrum was unusual.
