Event Description
|
Users reported that during a revision surgery to reposition the patient's existing growing rod construct, intra-operative malfunctions of the materials were reported.However, subsequent evaluation noted the components had been implanted in the first surgery and exhibited signs of post-operative loosening.Based on the resuls of the evaluation the event was deemed reportable with the awareness date of (b)(6) 2021.The loosening was asymptomatic and was not noted during the revision surgery.Available information suggests that the growing rod construct was intended to be adjusted and components were not intended to be replaced.However, the lock screw reportedly became deformed during these maneuvers and could not be removed; the rod was cut and a rod-rod connector was placed to re-connect the construct portions.
