[Passage from childhood to adulthood and craniovertebral malformations].

Craniovertebral malformations are infrequent in children. Their causes are numerous (Chiari, congenital bone diseases, metabolic diseases, and genetic anomalies). When symptomatic (seldom), these malformations require surgical decompression and fixation. Progress in therapy probably will postpone the occurrence of these signs and require cooperation between pediatric and adult physicians.
