Abstract
A locking nail includes a shank, at least one cross-bore close to one end and at least one cross-bore close to the other end. The cross-bores for receiving a bone screw each. An additional cross-bore located at one end of the nail is of an elongate shape in the longitudinal direction of the nail. A female thread is formed in a hollow-designed shank portion having the elongate cross-bore. A locking member with a male-threaded portion which is adapted to be screwed into the female thread in the hollow portion and interact with the bone screw in the elongate cross-bore in order to displace it transversely to its longitudinal axis in the cross-bore. A second cross-bore is provided for a bone screw between the elongate cross-bore and the adjacent end of the shank. The arrangement of the female thread is such and the length of the locking member and the location of the second cross-bore are sized such that the locking member largely leaves vacant the second bore even if the bone screw which is in the elongate cross-bore bears against the end of the elongate cross-bore facing the shank end. This allows for the insertion of a second bone screw in the second bore.
