Abstract

An intramedullary nail (10) suitable for insertion in a fractured elongate bone (12) and for an unusually simple fixation therein comprises a substantially straight stem (14, 114, 214, 314) extending between a proximal end (16, 116, 216, 316) and a distal end (18, 118, 218, 318), one of said ends (16, 18; 116, 118; 216, 218; 316, 318) comprising expansion means (20, 120, 220, 320) for the nail fixation to the bone, said expansion elements (20, 120, 220, 320) comprising at least an element (20a, 120a, 220a, 320a) realised with a shape-memory material. Further disclosed is an intramedullary nail comprising expansion means, said expansion means being operated by at least one driving element realised with a shape memory material.
