The causes of cervical spine weakness to support the head include cervical spondylosis, tuberculosis, cervical spine fracture and dislocation, etc. Depending on the cause of the disease, we can choose the treatments such as traction, brace immobilization, hot compresses, the use of drugs such as isoniazid, and surgery. 1. Cervical spondylosis: compression of blood vessels by cervical spondylosis can lead to insufficient oxygen supply to the brain, resulting in a feeling of dizziness and an inability of the cervical spine to support the head. Patients with cervical spondylosis can relieve their symptoms through bone traction and physical therapy, while severe cases need surgery for decompression and internal fixation. 2. Tuberculosis: patients with tuberculosis may have symptoms such as low-grade fever, night sweats, generalized weakness, etc. Patients with generalized weakness may feel that the cervical vertebrae are unable to support the head, and can be treated with drugs such as isoniazid and rifampicin. 3. Cervical vertebra fracture dislocation: patients with cervical vertebra fracture dislocation have no ability to support the head, and can be fixed by bone traction or wearing head, neck and chest support for the cervical vertebrae, and the fracture displacement is serious and needs to be surgically reset with internal fixation treatment. All of the above medications should be used under the guidance of a doctor, avoid self-medication. If the symptoms of cervical spine weakness in supporting the head are not relieved, or accompanied by other symptoms, you should go to the hospital in time, and give targeted treatment after clarifying the cause.
