Torticollis

Torticollis is a fixed or dynamic tilt, rotation, or flexion of the head and/or neck. The type of torticollis can be described depending on the positions of head and neck.

  • laterocollis : the head is tipped toward the shoulder
  • rotational torticollis : the head rotates along the longitudal axis
  • anterocollis : forward flexion of the head and neck
  • retrocollis : hyperextension of head and neck backward

A combination of these movements often may be observed.
