The sequelae of cervical spinal stenosis surgery are as follows: 1. Spinal reperfusion injury: in severe cases, it can cause paralysis in patients; 2. Inability to lift the shoulder: it is a common early complication after cervical spinal stenosis surgery, which is caused by the backward displacement of the spinal cord after surgery, which stretches the nerve roots in the neck and leads to weakness of the deltoid muscle, thus causing the inability to lift the shoulder. Most patients can gradually recover in 3-6 months after surgery. 3. Axial pain: It is caused by the nerve endings attached to the joint capsule, spinous process and ligaments being stretched after the nerve roots or spinal cord are stimulated.
