Chest closure

Conventional closure of primary sternotomy is done using many different methods, most often with surgical steel sutures.

An osteoporotic or fractured sternum, and obesity are the most frequently cited risk factors. There is no uniform osteosynthetic method for primary sternal closure and there is substantial variation in the perception of risk factors for sternal instability and possible surgical consequences among the surgical heart centers.

Stainless steel wires are currently used for median sternotomy closure in cardiac and general thoracic surgery; this method is effective, and fast. However, the wires in patients with additional risk factors can damage and cut bone during respiratory and chest motion, leading to instability and chest pain, and they can even increase the risk of dehiscence. Standard closure might not be adequate in such patients, and reinforcement of the closure site is needed.
