A method for reinforcing a sternum after a sternotomy or a sternal fracture, comprising the step of applying a reinforcing device, said method comprising:

• providing a plurality of elongated members forming a sternum reinforcing group extending on a surface portion along a longitudinal lateral edge of the sternum and fixed to said sternum, wherein the elongated members of the plurality of elongated members are each provided with a first connection part and a second connection part;
• providing said first and second connection parts being in the form of arms, wherein a first one of the arms extends in a first direction with respect to a central portion and a second one of the arms extends in a second direction with respect to said central portion, the second direction being opposite to the first direction;
• joining said first connection part of a first of said plurality of said elongated members with a second connection part of a preceding elongated member of the reinforcing group along the longitudinal lateral edge of the sternum;
• joining said second connection part of said first elongated member with a first connection part of a following elongated member of the reinforcing group along the same longitudinal lateral edge of the sternum;
• fitting a projecting portion provided at each of said plurality of elongated members in an intercostal space adjacent to the longitudinal lateral edge of the sternum.
