A device for implantation in an intramedullary space of a bone via a curved insertion path, the device comprises a curved proximal portion extending along an arc substantially similar to an arc of the curved insertion path, the proximal portion including a coupling arrangement at a proximal end thereof adapted to couple to a tool for one of intramedullary implantation and explantation and a flexible distal portion extending from a distal end of the proximal portion, the distal portion extending substantially straight in an unstressed state and having flexibility sufficient to permit being along the arc of the insertion path substantially without permanent deformation.
