Answer

By far, the most common complication reported requiring reoperation was displacement of the retrosternal stainless steel support bar (initially reported to occur in 9.5% of all patients). Such displacement can include a 90° rotation, a 180° rotation, or a lateral migration. Teenaged patients are at higher risk for complications, particularly pectus bar displacement, probably because of the increased pressure on the bar generated by a larger chest and more rigid chest cage. Today, the risk of bar displacement has been reduced to approximately 2.5% owing to new techniques of bar stabilization (described under Surgical technique in Surgical Care).
