The present invention relates to a universal modular bone segment transport device which is completely implantable within a part of a body of a patient, wherein the bone segment transport device is capable of transporting at least one bone segment of the patient from a start position to a target position which is remote from the start position, wherein the bone segment transport device comprises at least the following:a) a first fixation element, which is arranged for fixation on a first section of a bone of a patient,b) a second fixation element, which is arranged for fixation on a second section of the bone of the patient,c) a first transport element, which is arranged for fixation on a first bone segment which is located in an area between the second and the first section of the bone, wherein the first bone segment is to be transported by the bone segment transport device,d) a first drive mechanism, which is arranged for effecting a motion of the first transport element relative to the first and/or second fixation element, characterized in that the second fixation element is a separate piece which is separate from the first fixation element, wherein the second fixation element can be coupled to the first fixation element for transportation of the first bone segment.The device is universal, meaning that it can be attached to any commercially available lengthening nail. The device is modular, meaning it can be attached as a separate additional module if needed for segmental transport.
