Wry Neck Congenital Torticollis
Congenital torticollis is present at birth. Infants born with torticollis appear healthy at delivery. However, within the first few weeks, they develop swelling of the tissues on the side of the neck.
The neck swelling is due to an injury to the sternocleidomastoid muscle on one side of the neck. The two sternocleidomastoid muscles rotate the head from side to side. The injury usually occurs just before delivery, or during delivery. The swelling gradually resolves, but the injured sternocleidomastoid muscle becomes a stiff band of tissue. This can result in abnormal positioning of the neck.
