Event Description
|
It was reported that the patient underwent an initial cardiac surgery on an unknown date and the patient's sternum was closed with wire.Sometime afterward, on an unknown date, the patient presented with transverse sternal fractures as well as a 2.5cm gap in his sternum that did not heal.The patient then underwent a second procedure where the surgeon removed the wire and replaced it with sternal plating.Afterward, on an unknown date, part of the two plates used became dislodged from the sternum.All of the screws were intact in and still locked in the plate.Subsequently, the patient underwent a revision surgery in which the surgeon removed all sternal hardware and replaced it with new sternal plating.The surgeon believes that the gap in the sternum and the transverse fractures contributed to the instability of the chest and was not related to the use of the sternal plating.He did not think the further non-union of the sternum was due to the original usage of the plating.
