CTICasesSternal Dehiscence and hardware Migration
Imaging findings
Serial CT scans post-sternotomy show progressive manubrium separation, anterior mediastinal fluid collections, and migration of a hardware screw from a reconstruction plate into the mediastinal fluid over a four-day interval, secondary to sternal wound infection.
Key takeaways
Sternal dehiscence and mediastinitis can lead to osteomyelitis and hardware failure. Rapid migration of surgical screws or wire fractures over a short interval is a highly specific sign of underlying mechanical instability and active infection.
