Potential risks to any surgical procedure include unforeseeable complications caused by anesthesia, blood clots, undiagnosed medical problems such as silent heart disease, and rare allergic reactions. Complications of spinal surgery can include neurological damage, damage to the surrounding soft tissue and, where used, instrument malfunction. Most of these complications can be treated once they are detected, but sometimes they require a longer period of hospitalization or recovery, additional medications, and sometimes even additional surgery. Depending upon the type of surgery you are having, these risks will be explained by the primary surgeon. Other risks associated with implants used include device migration, loss of spinal curvature, correction, height, and/or reduction. As a patient, it is important to understand and follow your doctor’s advice so that the best possible outcome can be achieved. Surgery is not for everyone. Please consult your physician.
