Within the cavity ( 12 ) of an intramedullary nail, means such as a channel element ( 16 ) is mounted whereby a leading end ( 26 ) of a flexible elongate wire ( 22 ) is guidable from insertion into a proximal lateral aperture ( 20 ) to emerge from a distal lateral aperture ( 30 ), with the trailing end of the wire ( 22 ) still projecting from the proximal aperture ( 20 ). In this way when the nail is inserted into the medulla of a bone, across a fracture, it can be secured to the bone near both its ends. Two guide means, such as two channels ( 31, 33 ) of a channel element ( 16 ), with deflected guide wall portions ( 34, 38 ), or two conduits (FIGS. 8 to 13 ) guiding respective fixing wires between respective proximal and distal apertures, may usefully be provided.
