How long to wear a neck brace after cervical spondylosis surgery should be decided according to the type of cervical spondylosis and surgical methods. Common surgical methods include minimally invasive surgery, anterior or posterior incision surgery, etc., and the general wearing of a neck brace ranges from 4~6 weeks to 3 months in length. 1. Minimally invasive surgery: If minimally invasive surgery is performed for neurogenic cervical spondylosis, such as intervertebral foramenoscopic disc removal surgery or radiofrequency ablation surgery, etc., the cervical brace is usually worn for 4~6 weeks, and then the neck muscles will be actively exercised under the guidance of the doctor. 2. Anterior or posterior incision surgery: If spinal cord cervical spondylosis is performed with decompression of the vertebral plate, vertebral fusion and other incision surgeries, in order to prevent excessive neck movement, it is necessary to wear a cervical brace for at least 3 months, and when the vertebral body is completely fused in the radiographs, the cervical brace can only be taken off to perform functional exercises. After cervical spondylosis surgery, the wearing time of the neck brace should be judged by the doctor according to the specific condition, and the patient should not blindly remove it on his own, so as not to cause adverse effects.
