Torticollis in children can be due to atlanto-axial rotatory subluxati
on. If diagnosis, based on plain lateral radiography and on computed t
omography and specific treatment are delayed, reduction becomes diffic
ult to accomplish. Atlanto-axial fusion might be indicated to cure the
instability. Thus, a diagnostic delay may prevent restoration of cerv
ical spine function. In acquired torticollis in children, radiographic
evaluation is indicated if the symptoms are not relieved within 1 wel
l, but immediate radiography is indicated in traumatic torticollis.
