  • Look Inside

Clinical, biological, histopathological and laboratory data are reported on a 13-year-old male with atlanto-axial, atlanto-occipital hypermobilities, cervical canal stenosis, hypoplastic atlas and hypoplastic first rib in the EhlersDanlos syndrome. He developed frequent attacks of sudden tetraplegia or tetraparesis and numbness below C2 due to trivial neck injuries. Examination revealed marked hypermobilities of all joints the cutis elastica (Fig. 1), spastic tetraparesis and fasciculation of the tongue. Occipitoatlantal hypermobility measured by Wiesel and Rhothmans' method revealed 5 mm horizontal translation (Fig.2).
