title: [Traumatic spondylolysis in the hedgehog. A contribution to the problem of isthmus dysplasia].
abstract: Traumatic spondylolysis in a hedgehog is reported. On the basis of that rare observation the "dysplastic" thinning of the vertebral isthmus frequently associated with spondylolysis in man is claimed to be related to the "neuroenveloping" function of the spine shared with that of the neurocranium. Dysplasia of the isthmus results from abnormal ganglio-foraminal interrelation in the embryo rather than from any primary derangement of the vertebral bone growth proper.
