摘要：
The surgical nail, here in the form of an intramedullary nail, has a central axis, a longitudinal borehole with a diameter D extending coaxially with the central axis, a casing with an inner surface and a transverse borehole, extending transversely to the central axis with the cross-sectional profile F and the borehole axis. A component, which narrows the cross-sectional profile F, is provided in the longitudinal borehole in the region of the transverse borehole. By these means, the clearance, which is usually present between the medullary nail and the locking screws that have been introduced therein, can be eliminated without risk and an improved holding force as well as an improved guiding effect between the locking screw and the medullary nail can be achieved.
