ABSTRACT:
A locking nail for placement in the marrow space of tubular bones for the care of bone fractures, with an elongate, essentially cylindrical shank with a number of essentially radial openings for accommodating locking screws. At least one radial, elongate opening extends in the longitudinal direction of the shank and at least two sliding blocks are unrotatably guided within the shank and are secured against a movement away from one another so that at least one opening at an angle to the longitudinal direction is formed from at least one intermediate space between the sliding blocks. This opening is aligned to the elongate opening for accommodating a locking screw. In another embodiment, only one such sliding block is used (and can be selected from any of a suitable set, for example a set in which the blocks of the set all have substantially the same length but have transverse bores positioned at a variety of different positions and at different angles with respect to the longitudinal axis of the nail).
