Stable construction of the sternum after broad radical resection of malignant tumours.

Radical resection of primary or solitary secondary malignant sternal tumours is indicated in patients without metastases. Sternal reconstruction may be indicated in large defects to prevent pulmonary complications, to achieve protection of intra-thoracic organs and to obtain a good aesthetic result. In this article, a modified surgical technique is described to fill and reconstruct large defects after radical resection of a primary or secondary malignant sternal tumour. The technique makes use of a methyl methacrylate composite within two layers of polypropylene mesh enforced by steel wires through the sternal ends of the defect enhancing stability. This modified technique can be easily applied, making curative broad radical resections of the sternum feasible.
