Cervical spinal stenosis can be divided into developmental cervical spinal stenosis and degenerative cervical spinal stenosis. When the anterior and posterior diameter of cervical spine is less than 13 mm measured on cervical spine slice, it is defined as relative cervical spinal stenosis, and when this value is less than 10 mm, it is absolute cervical spinal stenosis. Cervical spinal canal stenosis can lead to compression of the cervical spinal cord, and the corresponding clinical symptoms, such as limb numbness, walking instability, floating walking, hands are not flexible, easy to drop things, even abnormal urine and urine. Most cases of cervical spinal stenosis require surgical treatment. Cervical spinal stenosis can be operated by anterior and posterior approaches according to the different segments of the stenosis.
Firstly, the sequelae of anterior surgery are introduced. Titanium plate screw fixation and bone graft fusion are needed in anterior surgery. Postoperative screw loosening, plate fracture, screw withdrawal may occur. Bone graft incompatibility may also occur. If this happens, another operation is needed. Another case is esophageal fistula, which is a serious complication of anterior cervical surgery. Esophageal leaks can cause wound infections. Anterior cervical approach may also have some vascular and nerve injuries during the operation. If the superior laryngeal nerve or recurrent laryngeal nerve is injured, it may cause hoarseness and cough after operation. Most of this situation can be restored after three months, but some of it can not be restored. In addition, if there are more fixed segments and more fusion segments, there may be limitations of cervical spine movement after surgery, mainly for flexion, extension and rotation.
Next is the common sequelae of cervical posterior surgery. For example, the wound infection of the posterior cervical surgery, the wound does not heal. Recurrence of spinal stenosis occurred again after operation. Postoperative cervical movement was limited. The
