Displacement of the atlanto-axial joint was first described by Corner. We report six children with atlanto-axial rotatory fixation (A. A. R. F.). Five cases who had a short interval between injury and diagnosis were treated by Short-tern Crisson traction and so, achieved reduction and ealy return of function. One case with a delay in trea tment required cervical fusion for instability.
Eary diagnosis is important, so A. A. R. F. should be looked for in all cases of acute torticollis.
