Method of reinforcing a sternum after a sternotomy or a sternal fracture

1. 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.

2. The method according to claim 1 , further comprising forming the connection parts of said elongated members as prismatic couplings with the corresponding connection parts of the respective preceding and following elongated member of the group.

3. The method according to claim 1 , further comprising making the elongated members from a biocompatible, shaped and bent plate material.

4. The method according to claim 1 , further comprising shaping said projecting portion for the intercostal space as a body portion for each of said elongated members extending between said connection parts and at right angles to them.

5. The method according to claim 4 , further comprising shaping said body portion to be U-shaped having parallel free edges, orthogonally bent outwards, to enclose between them a clamping element which clamps the elongated member to the sternum.

6. The method according to claim 5 , further comprising making said clamping element of a stainless steel wire.

7. The method according to claim 5 , further comprising making said free edges of the U-shaped projecting portion extend from the projecting portion in the form of legs and fitting said legs in the intercostal space of the thorax of a patient, laterally to the sternum, and bending said legs in a mutually opposite direction, on the internal side of the thorax.

8. The method according to claim 7 , further comprising providing a separated splint provided with a multiplicity of slots for the passage and the retaining of said legs before the legs being bent from the body portion in a mutually opposite direction.

9. The method according to claim 8 , further comprising providing said splint, on one side thereof, with guiding notches and accommodating said clamping element in said guiding notches.

10. The method according to claim 1 , further comprising providing said first connection part with a male arm and slidingly fitting said male arm in a corresponding second connection part of a preceding elongated member.

11. The method according to claim 10 , further comprising providing said male arm with a rectangular flat cross-section profile.

12. The method according to claim 1 , further comprising providing said second connection part with a female arm and slidingly fitting said female arm in a corresponding first connection part of the following elongated members.

13. The method according to claim 12 , further comprising providing said female arm with a hollow channel-shaped cross-section.

14. The method according to claim 1 , further comprising fitting the elongated members of said reinforcing group bilaterally to the sternum along two sternum longitudinal lateral edges.

15. The method according to claim 1 , further comprising fixing two series of elongated members to the sternum, each along a respective sternum longitudinal lateral edge.

16. The method according to claim 15 , further comprising a locking the two series of elongated members to the sternum by a clamping element passing between edges of the elongated members.

17. The method according to claim 1 , further comprising interpenetrating said elongated members.

18. The method according to claim 1 , further comprising abutting the end of the first or second connecting part of one member against the projecting portion of an adjacent member.

19. The method according to claim 1 , further comprising coupling the first connection part of one elongated member slidably with the second connection part of a preceding or following elongated member of the reinforcing group along the longitudinal lateral edge of the sternum.

20. The method according to claim 19 , further comprising adjusting the two elongated members to a rib width of a patient by selecting an amount of mutual sliding between said first and second connection part such that the two elongated members are spaced from each other so that the two elongated members are adjusted to a rib width of a patient.

21. The method according to claim 1 , further comprising closing the sternum by tapes and/or bands received between edges of one or more elongated members.

22. A method for reinforcing a sternum after a sternotomy or a sternal fracture, said method comprising:

applying a plurality of elongated members along at least one longitudinal lateral edge of the sternum, wherein the elongated members are each provided with a first connection part and a second connection part;

slidably joining a first connection part of a first elongated member with a second connection part of an adjacent preceding elongated member along the longitudinal lateral edge of the sternum;

slidably joining a second connection part of the first elongated member with a first connection part of an adjacent following elongated member along the same longitudinal lateral edge of the sternum;

fitting a projecting portion of one or more of said elongated members in an intercostal space adjacent to the longitudinal lateral edge of the sternum; and

fixing the elongated members to the sternum.
