Implant for long bones and treatment method

Method for implanting an implant for connecting parts of a long bone that has broken with a smooth break, wherein the implant comprises:

• two anchor parts,
• a cord, and
• a shaped piece,
• wherein:
• the anchor parts can be secured to the cord, and
• the shaped piece is made of a resorbable material and has at least one through-opening, through which the cord can be guided so that the shaped piece extends around the cord and between two anchor parts,
• the method comprising:
• forming a first opening in a first bone part that runs in a longitudinal direction inside the long bone from a first end region of the long bone through a first wall of the long bone to a first fractured end,
• forming a second opening in a second bone part that runs in the longitudinal direction inside the long bone from a second end region of the long bone through a second wall of the long bone to a second fractured end,
• threading a cord and the shaped piece through one of the first opening, the second opening, the first fractured end, and the second fractured end, wherein the cord runs through the shaped piece,
• threading the cord through the second opening, so that the shaped piece is threaded onto the cord between the fracture surfaces of the long bone,
• securing the cord at the first end region of the long bone by means of a first anchor part, and
• pulling the cord taut, and
• securing the cord at the second end region of the long bone by means of a second anchor part;
• wherein:
• the two anchor parts are secured to the cord outside of the long bone and once secured to the cord provide a compressive force to the first and second bone parts;
• and
• the shaped piece extends in a medullary cavity of the long bone between the two anchor parts.

Method for implanting an implant for connecting parts of a long bone that has broken with a smooth break, wherein the implant comprises:

• an intramedullary nail comprising:
• a thickened region at a first end, and
• a fastening means for a cord at a second end,
• a cord, and
• an anchor part,
• wherein:
• the anchor part is adapted to be secured to the at least one cord, and
• the cord is adapted to be secured to the fastening means of the intramedullary nail, so that the cord extends between an anchor part and the intramedullary nail, the method comprising:
• making accessible a first bone end of a first bone part of a long bone that has broken with a substantially smooth break,
• forming a first opening in the first bone end of the first bone part that runs in a longitudinal direction inside the long bone from a first end region of the long bone and through a first wall of the long bone in a direction of the fractured end of the long bone,
• making accessible the second bone end of a second bone part of the long bone that has broken with a substantially smooth break,
• forming a second opening in a second bone part of the long bone that runs in the longitudinal direction from a second end region of the long bone, through a second wall of the long bone in a direction of the first end region of the long bone,
• securing the cord at the fastening means of the intramedullary nail,
• threading the intramedullary nail at least partially through the first opening,
• threading the cord through the second opening,
• pushing the intramedullary nail further through the first opening and through the fracture surfaces in a direction of the second end region of the long bone such that the intramedulary nail extends in the medullary cavity of the long bone,
• securing the intramedullary nail at the thickened region at the first end region of the long bone,
• pulling the cord taut, and
• securing the cord to the second end region of the long bone by means of a an anchor part positioned outside of the long bone such that a compressive force is provided to the first and second bone part.
