Torticollis in children is a frequently encountered problem. Whereas non-traumatic torticollis usually allows a non-urgent work-up, traumatic torticollis-even in the absence of neurologic abnormalities-needs prompt analysis for structural damage of the spinal column and myelum. Even a trauma as mild as a head-over-heels may result in atlanto-axial subluxation as demonstrated by this patient as described in this case report. In all children with post-traumatic torticollis, further analysis is needed. Atlanto-axial subluxation without neurological or radiological abnormalities can be treated conservatively with a soft collar and analgesics.
