Crooked neck – a sloping neck, mostly due to contracture of the sternocleidomastoid muscle, but also due to deformities of the first and second cervical vertebrae, as well as optic. A cervical mass can also be found half a month after birth, with larger children having their heads tilted to one side and their chins tilted to the other. Most of them are combined with congenital hip dislocation. Treatment The earlier the better, early conservative treatment, i.e., manipulation + postural correction. Surgical treatment is required for older age findings. Conservative treatment is passive traction and massage. Passive pulling: reverse the direction of the crooked neck, set the head straight and favor the other side (pull the head to the healthy side, several times a day, 10-15 strokes each time). Apply sand pillow to fix it during sleep. As the child grows, the strength of the manipulation increases, the occiput rotates to the healthy side, the jaw to the affected side, several times a day, persistently, most of them can obtain satisfactory results. Massage: mainly for the contracture of the sternocleidomastoid muscle massage, play a role in relaxing muscle fibers. There are many massage techniques, but the principles and principles are the same. Surgical treatment is suitable for children around 2 years of age, generally using a transverse incision at the proximal end of the clavicle on one transverse finger. In mild cases, only the root of the sternocleidomastoid muscle is cut off, and an orthopedic neck brace is applied after surgery to maintain and slightly over correct the position, and the child’s jaw is frequently rotated to the affected side and the occiput to the healthy side. For those who are over 4 years old and have a severe squint, upper and lower sternocleidomastoid muscle severing and release is feasible. Because of more folds in the neck, intracutaneous sutures are used after the surgery, and the postoperative scars are basically invisible.
