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).
congenital muscular torticollis
Congenital fibrosis of the sternocleidomastoid muscle in the newborn, causing rotation of the infant's head to the opposite side. The condition usually becomes evident in the first 2 weeks of life. 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.

Torticollis from inequality in sight of the two eyes.
Torticollis with recurrent but transient contractions of the muscles of the neck and esp. of the sternocleidomastoid. Synonym: intermittent torticollis
Synonym: cervical dystonia
Botulinus toxin has been used to inhibit the spastic contractions of the affected muscles. See: botulinus toxin
Torticollis from caries of the cervical vertebrae.
