Abstract
An apparatus (10) for attaching a first section (17) of a bone (12) to a second section (18) of the bone. The second section (18) is separated from the first section (17) by a fracture (14). The apparatus (10) comprises a bone screw (20) having a platform (24) and at least two helical spikes (50 and 52) for embedding into at least one of the first and second sections (17 and 18). The helical spikes (50 and 52) project tangentially from the platform (24). The helical spikes (50 and 58) have a tip portion (58) which penetrates into the bone (12) as the platform (24) is rotated. The bone screw (20) has a first condition in which a first portion (58) of the bone screw extends into one of the first and second sections (17 and 18) and a second condition in which a second portion (24) of the bone screw extends into the other of the first and second sections to compress the first and second sections together.
