Cervical spine surgery can also loosen the plate after fixation. However, such cases are usually rare in regular hospitals with professional doctors. After cervical spine surgery to fix the plate for a period of time, the body of the plate and the surrounding bone after long-term wear and tear will produce a certain amount of volume, the plate itself may also slowly electrolysis thin, resulting in the loosening of the plate. In addition, premature activities such as neck flexion, extension and rotation after postoperative immobilization, or trauma to the neck may also cause the plate to loosen. In patients with osteoporosis, the affinity between the bone and the plate decreases when the plate is immobilized, which creates a certain amount of space that can lead to loosening of the plate over time as the neck is moved. Therefore, it is important to take bed rest after cervical spine surgery to immobilize the plate and avoid excessive neck activity too early. Post-operative X-rays should also be reviewed regularly to observe the recovery of the cervical spine.
