Telescopic nail and associated perforating tool

A method for implanting a telescopic nail comprising:

• providing a telescopic nail comprising:
• a hollow stem;
• a rod inserted telescopically into the hollow stem;
• a first fastening element configured to couple to an end of the hollow stem for fixing to a first long bone end;
• a second fastening element configured to couple to an end of the rod for fixing to a second long bone end;
• said end of the hollow stem being provided with a coupler for coupling to a coupling end of a perforating tool which is configured to be inserted into a cavity formed in the bone for insertion of the nail;
• preparing said perforating tool, wherein the coupling end of the perforating tool comprises a counter-coupler designed to be coupled to said coupler of said end of the hollow stem of the telescopic nail;
• inserting an end of the perforating tool opposite to the coupling end inside the cavity through an end of the bone;
• coupling the coupler of said end of the hollow stem of the telescopic nail together with the counter-coupler of the coupling end of the perforating tool;
• advancing the perforating tool inside the cavity until it comes out completely from the other long bone end, drawing along with it the hollow stem into the cavity;
• and
• uncoupling the perforating tool from the hollow stem.
