It usually takes about 3 months after minimally invasive anterior cervical surgery to remove the neck brace, depending on the degree of bone fusion. The stability of the cervical spine can be severely disrupted during anterior cervical surgery or posterior cervical surgery. After minimally invasive anterior cervical surgery, a neck brace should be worn to protect the neck from flexion, extension and rotation, and the immobilization time is usually about 3 months. The neck guard can only be removed after bone fusion. Three months after the minimally invasive anterior cervical surgery, the CT or MRI examination of the cervical spine can be reviewed, and if it suggests that the intervertebral space in the surgical area has been completely fused, the functional exercises of the neck can be carried out. Neck flexion and extension, left and right rotation, and then neck rotation can be performed at the beginning. Usually, after anterior cervical spine surgery, a cervical neck brace needs to be worn for about 3 months. Anterior cervical spine surgery usually removes disc tissue and fuses and fixes the vertebrae, so recovery time is longer. Be careful not to do strenuous activities on your neck to prevent injury. Exercise should be gradual and stop immediately if you feel discomfort in your neck.
