Separation of the sternal halves may be total, involving the entire sternum, or partial, being limited to … Sternal instability was confirmed by physical examination and confirmed by chest tomography. Can it improve patient function and ease activities and exercise? The sternal instability scale (SIS) is a non-invasive manual assessment tool that can be used to detect early bony non-union or instability following CSI; however, its reliability is unknown. Indications for plate osteosynthesis have been summarized by Harston: displaced and overlapped fractures that cannot be corrected by closed reduction, sternal instability, chronic nonunion and severe pain making with restriction of respiratory movements (15). Over 400,000 cases of open heart surgery are performed annually in the United States with an incidence of 1%–3% surgical site infections.1 Superficial sternal wound infections involve skin and superficial soft-tissue structures only and can often be treated with limited courses of antibiotics and local wound care.
