Anatomy. Luschka joints are small synovial articulations, measuring 2 × 4 to 3 × 6 mm., situated between the five lower cervical vertebral bodies. They are located anteromedially to the mixed nerve root and posteromedially to the vertebral artery, vein, and sympathetics as these pass through the vertebral foramen.
Is Dandy-Walker syndrome considered a disability?
Some children have a buildup of fluid in the brain (hydrocephalus) that may cause increased head size (macrocephaly ). Up to half of affected individuals have intellectual disability that ranges from mild to severe, and those with normal intelligence may have learning disabilities.

A incorrect diagnosis of the variant form can be made at gestational ages of less than 18 weeks because the cerebellar vermis may not yet be completely developed.
