Specific entities affecting the craniocervical region: Down's syndrome.

INTRODUCTION

The ligamentous laxities and bony abnormalities associated with Down's syndrome, os odontoideum, achondroplasia, osteogenesis imperfecta, and basilar invagination have been discussed with the imaging of the craniocervical junction. These are significant and require suspicion when dealing with children with the previously mentioned entities.

CONCLUSION

Previous adverse surgical results in managing these patients reflect the lack of understanding of the underlying pathology and the appropriate surgical treatment.
