The present invention provides a two-part telescopic intramedullary orthopedic device capable of connecting two adjacent fractured or severed bone ends, characterized in that said device comprises a first section inserted into the medullary cavity of one of the fractured or severed bone ends, and secured thereto, and a second section inserted into the medullary cavity of the other fractured or severed bone end and secured thereto, wherein said second section comprises an internal space communicating with an external opening, and wherein said first section is more or less telescoped within said internal space of said second section, and wherein one of said sections comprises a ferromagnetic material and the other section is either constructed entirely of a non-magnetic material or comprises a ferromagnetic material, wherein the ferromagnetic section(s) are actuable by an external magnetic field, such that one section may be caused to move axially in relation to the other section, and wherein said axial movement may be either bidirectional or essentially unidirectional. In addition, the invention encompasses a method for changing bone length as well as a method for enhancing bone fracture healing.
