Torticollis, also called wryneck or twisted neck, is a condition caused by tightened or shortened neck muscles. Children with this condition often have poor head control and tilt their head towards one side with the chin turned to the other side. This is usually observed in the first 6 to 8 weeks of life. In newborns, it can occur as a result of abnormal positioning of the head in the womb. In older children, it may result from injury to the neck muscles or from infections.
