Abstract
The invention relates to a bone screw, particularly for use with external splints in fracture stabilization, comprising an elongate cylindrical body (2) of predetermined length and diameter tapering into a threaded end portion (5) which terminates with a tip (6), and an opposite screw-handling end (3). The screw-handling end (3) has substantially the same diameter as that of the elongate cylindrical body (2) and comprises a flat (7) extending parallel to the axis of the cylindrical body over the main part of the cylinder body portion unoccupied by the thread. In a further embodiment, the screw-handling end (3) is formed with a plurality of flats (8) extending parallel to the axis of the cylinder body (2) at predetermined spacings. These flats extend over the main part of the cylindrical body portion unoccupied by the threadway and alternate with lands (9).
