Spinal cord injury (SCI) occurs when there is any damage to the spinal cord that blocks communication between the brain and the body. It can be caused by trauma (diving, auto accidents, falls, surgical procedure, etc.), viral infections, diseases (Arnold-Chiari syndrome, tumors, etc.). If the injury is at levels of C1-C3, respiratory failure occurs. The patient needs to be breathing with the help of a mechanical ventilator which pumps air into the lungs or be implanted with a breathing pacemaker that contracts the diaphragm similar to the natural breathing.

Below are the only two surgical options for SCI:
