[Atlanto-axial rotation-fixation in a child with clavicular fracture].

A case of an eight-year-old boy who had sustained both a fractured clavicle and rotatory atlanto-axial fixation is described. The last diagnosis was missed for four and a half months. The diagnosis was made in combination with cineroentgenography and computed tomography scanning. Conservative treatment with external traction was first attempted, after which the patient was operated twice with posterior fusion between C-1 and C-2. At six month follow-up the child was without pain, had neutral head holding and about two-thirds of normal rotation.
