Torticollis primarily involves which muscle?

• A. Clavicle
• B. Torn neck muscles
• C. Erb's palsy
• D. Sternocleidomastoid muscle

Answer: (D)

Torticollis, commonly known as "twisted neck," primarily involves the sternocleidomastoid muscle. This muscle plays a crucial role in neck movement and the positioning of the head. When there is an abnormal shortening or spasm of the sternocleidomastoid muscle, it can result in the head being tilted to one side and the chin being turned towards the opposite side, which is characteristic of torticollis. The condition can arise from various factors, including congenital issues, muscle injury, or even as a result of positioning in utero. In particular, congenital torticollis may occur when the sternocleidomastoid muscle is shortened at birth due to factors like birth trauma or positioning in the womb. Understanding the involvement of this specific muscle is essential for diagnosis and subsequent treatment plans, which may include physical therapy or surgical intervention in more severe cases.
