Event Description

Information was received from healthcare provider (hcp) via a manufacturer representative regarding an event which occurred post a t h4-l3 spinal fusion procedure in a patient diagnosed with idiopathic scoliosis.It was reported that both sides of the th12 and ps tip were penetrated as it was near the artery; safety measures were taken to remove the left th5, and the ps was also externally penetrated.It is believed that the cause was the selected screw being too long for the vertebral body.Th5 left had been punctured outward.The cause is unknown, but there is no malfunctioning information at the time of placement.As both cases became noticed after the patient awakening from anesthesia, repeat surgery with re-anesthesia was performed.The punctured screw was removed and no new screw was placed. there was no patient symptom reported.There were no further complications reported regarding the event.
