Recently, Dongdong, who will start first grade at the beginning of the school year, was taken care of by his parents from his grandmother’s house in the countryside. DongDong has been with his grandmother since he was a child, and his parents are young and inexperienced in taking care of children in their daily lives. Because he slept on a pillow the same height as his parents, he woke up the next day with a headache and a sore nose. At first, his mother did not care, but one morning soon after waking up, Dongdong again cried head and neck pain and accompanied by difficulty in turning his head, his parents found that the child’s entire neck feels “crooked. His parents realized that his whole neck felt “crooked”, and they rushed him to the Department of Spinal Neurosurgery of the First Affiliated Hospital of Chongqing Medical University for treatment. After consultation and examination, Prof. Yan Yi diagnosed Dongdong as cervical atlantoaxial subluxation, and after traction with occipitomandibular band, Dongdong was discharged from the hospital yesterday. Coincidentally, this year’s 9-year-old YaYa also because of sleep “high pillow” to cervical atlantoaxial joint serious dislocation. YaYa is at noon in the school nap pillow their arms to sleep, woke up to find their neck can not move. In the hospital for more than twenty days, in the cervical atlantoaxial joint completely reset after discharge. Currently, the number of cases of cervical atlantoaxial dislocation in children caused by sleeping on “high pillows” has increased significantly. Professor Yan Yi of the Department of Spinal Neurosurgery at the First Affiliated Hospital of Chongqing Medical University introduced that the first cervical vertebra connected to the skull is called the atlas, the second cervical vertebra is called the central vertebra, and the shape is circular, together with the ligaments around the joints, known as the atlantoaxial joint. This joint mobility is very large, most of the head rotation function by it to complete, but also relatively fragile, especially young children’s atlantoaxial joint is particularly vulnerable. If a child’s head and neck move with force, such as when sleeping on a high pillow and suddenly stretching or twisting the head, it may lead to cervical subluxation, which manifests itself as head and neck pain or difficulty in turning the head, and severe neurological dysfunction. Prof. Yan suggested that parents educate their children good habits, create good conditions for growth, do not let the “high pillow” to bring unnecessary harm to children.
