Abstract
The present invention is generally applicable to the field of bone surgery devices and particularly relates to A locking device for intramedullary nails which device is designed to be at least partly inserted in an intramedullary nail (2) for locking it in position in the medullary cavity (M) of a fractured bone (B). The device comprises at least one fixation screw (3) having an axis of rotation (X) and a threaded axial end (4) for stable screwing into the wall of the medullary cavity (M). The device (1 ) is provided with elastic lock means (5) interacting with the fixation screw (3) to oppose rotation thereof and lock the nail (2) in position within the medullary cavity (M). An intramedullary nail may comprise such device.
