[Development of fused vertebrae in swine]

Radiographical findings are reported on the vertebral column of healthy weanling pigs and of two pigs with connatal formation of block vertebrae and clinically visible kyphosis in the lumbar region. The diagnosis of congenital malformations of the vertebral column in two patients is based on the anamnesis, the lack of locomotor disorders and radiographic-morphologic examinations showing fusions of vertebral bodies, arches and spinous processes as well as additional dorsal hemivertebrae but no inflammatory reactions.
