a first tube extending in an axial direction of the intramedullary nail,
a second tube extending in the axial direction of the intramedullary nail, which second tube is coupled with the first tube to be axially displaceable within one another,
a first locking opening, for locking the intramedullary nail in a bone fragment of the long bone, in an end area of the first tube facing away from the second tube,
a coil, which is disposed in a coil area of the first tube between the first locking opening and the second tube, and
a drive which is electrically connected to the coil,
wherein the first tube extends uninterrupted in the axial direction between the first locking opening and the second tube, wherein the first tube has an outer constricted section in the coil area, and wherein the coil is wound around said outer constricted section of the first tube, wherein in the coil area the coil is arranged radially outside the first tube.
