Torticollis.
A condition in which the head is twisted to one side. It may be caused by the contraction of a scar, such as that resulting from a burn, or by paralysis of some of the muscles; as a result of injury at birth; or trauma to the area later in life. Treatment is by an orthopaedic collar, heat or ultrasound, or physiotherapy. Sometimes a local injection of botulinum toxin will produce temporary relief. Rarely, surgery is necessary.
Unusual tilting and rotating of the head can occur, potentially resulting from neck muscle damage or spasms.
