To avoid the complications of internal pneumatic stabilization for flail chest, we performed stabilization of the chest wall with a metal bar using the Nuss procedure. Here, we used a highly elastic lightweight biocompatible titanium alloy Chest Way (Solve Corporation, Kanagawa, Japan), enabling magnetic resonance imaging. The patient was a 37-year-old man(More)
