A distal aiming device adapted to be connected to an x-ray apparatus is independent of the type of x-ray apparatus being used. A nail holding mechanism detachably receives the proximal end of an elongated locking nail. The locking nail is held approximately in parallel with an elongated aiming head retaining mechanism which for its part is fitted on a holding arm capable of displacement about the axis of the locking nail being held in the nail holding mechanism. The aiming head retaining mechanism carries an aiming head and is capable of displacement in a direction approximately in parallel with the axis of the nail being held in the nail holding mechanism. An adjusting pin is adapted to be accommodated by the aiming head in a direction normal to the axis of the locking nail.
A distal aiming device for a locking nail comprising an aiming head which is provided with a bore and is carried by an elongated aiming head retaining means, a nail holding means for detachably receiving the proximal end of the locking nail, a holding arm connected to the nail holding means and capable of rotation about the longitudinal axis of the locking nail being held in the nail holding means, said aiming head retaining means being releasably fitted on the holding arm and being capable of reciprocating displacement relative to the holding arm and the nail holding means in a direction parallel with the longitudinal axis of the nail, and an adjusting pin capable of being received by the aiming head within said bore in a direction normal to the longitudinal axis of the locking nail,
