torticollis (tort?i-kol'is) [L. tortus, twisted + L. collum, neck]
Stiff neck associated with muscle spasm, classically causing lateral flexion contracture of the cervical spine musculature. It may be congenital or acquired. The muscles affected are principally those supplied by the spinal accessory nerve. Synonym: wryneck
The condition may be caused by scars, disease of cervical vertebrae, adenitis, tonsillitis, rheumatism, enlarged cervical glands, retropharyngeal abscess, or cerebellar tumors. It may be spasmodic (clonic) or permanent (tonic). The latter type may be due to Pott disease (tuberculosis of the spine).

Treatments include physical therapy or, in refractory cases, surgical division of the muscle. Synonym: fibromatosis colli
An abnormal position of the head owing to organic shortening of the muscles.
