Abstract

A fixation device comprises an outer hollow elongate member (11) having a plurality of holes (16a...16h) in its outer wall. An inner member (14) carries a plurality of pins (15a...15h). To use the fixation device, the device is placed in a suitable cavity or hole and the pins are extended through the respective holes. The device may be used as an intra-medullary bone fixation device for fixing fractures in bones, or as a device used in the building industry.
