Three-dimensional modelling and printing in anterior chest wall reconstruction and stabilisation.

Anterior chest wall instability as a result of sternocostal non-union is a rare complication but can give rise to invalidating pain and cardiac arrhythmias. A woman in her 40s was referred to us with anterior chest wall pain and instability after a modified Ravitch procedure. Sternocostal pseudoarthrosis was seen for which multiple operations were performed which were complicated by low-grade infections. A patient-specific three-dimensional modelled and printed prostheses was used in an operation to both lift the sternum for pectus correction and to reconnect the sternum and the sternal costal junction to regain anterior chest wall stability.
