- FIG. 9 seen the fastening nail of FIG. 7 in a side view rotated by 90 ° to the view of FIG. 8, viewed from the left in FIG. 8.
- the fastening nail according to the invention in the exemplary embodiment shown there has a nail head 12 with a head surface 14 and a pressing surface 16, which, like all the others, with respect to a longitudinal axis 18 of the fastening nail, follows Components of the fastening nail to be described are rotationally symmetrical.
- a nail shaft 20 has an essentially cylindrical holding part 22 and a tip part 24 shown in the drawing below, formed integrally therewith, the cylindrical outer surface of the holding part 22 merging into a conical surface 26 of the tip part 24.
- the cylindrical holding part 22 has two annular shoulders 28 which merge into the lateral surface of the holding part 22 in the direction of the nail head 12 with an annular surface 30 running essentially perpendicular to the longitudinal axis 18 on the one hand and with an inclined surface 32 towards the nail tip on the other hand.
- annular surface 30 running essentially perpendicular to the longitudinal axis 18 on the one hand and with an inclined surface 32 towards the nail tip on the other hand.
- conical surface 26 of the tip part 24 in the direction of the nail tip adjoins this at the same time limiting cylinder extension 34.
- the fastening nail is produced by preferably thermoplastic material liquefied from the nail tip in a suitably designed injection mold a bioresorbable polymer is filled in, the chain molecules of the plastic material in the region of the nail shaft 20 or the holding part 22 being oriented essentially parallel to the longitudinal axis 18 of the fastening nail.
- the cylinder extension 34 is formed by the injection molding extension. After the fastening nail has been shaped, it can be used without reworking after sterilization etc.
- the nail shaft 20 heats up to body temperature.
- the chain molecules of the plastic material oriented parallel to the longitudinal axis 18 try to contract or shrink while simultaneously expanding the nail shaft 20. This increases the holding pressure within the bore in the sense of an interference fit.
- the holding part 22 has an axial longitudinal slot 36 over part of its axial longitudinal extent, which also passes through the tip part 24 and is open to the nail tip, following the cylinder extension 34.
- the longitudinal slot 36 enables the holding part 22 to be compressed in a resilient manner and the latter to be firmly seated in the bone bore.
- FIG. 3 is characterized by this from that the holding part 22 of the nail shaft 20 is provided with a series of spherically spherical, relatively flat holding projections 38. These can be compressed slightly when the fastening nail is driven into the bone hole, which ensures that it is inserted correctly and that the fastening nail is well seated in the bone hole.
- the essentially cylindrical holding part 22 of the nail shaft 20 is provided with a slight bulge 40, which also allows a slight compression of the nail shaft 20 when driving the fastening nail into the bone bore, while at the same time ensuring a firm interference fit Insertion of the fastening nail.

- the head surface 14 is essentially concave in the overlap region 46, viewed from above in the plan view, and essentially convex in the contact region 44. Both the contact area and the overlap area 46 merge with a gentle rounding into the lower contact surface of the nail head 12 shown in FIG. 7 below. The contact area 44 and overlap area 46 also merge smoothly and continuously with respect to the head surface 14.
- the nail head 12 merges into the nail shaft 20 via a spacer 47 which has a larger diameter than the nail shaft 20.
- the lateral surface of the spacer 47 has the shape of a partial cone drawn inwards in the direction of the longitudinal central axis of the fastening nail.
- the height of the partial cone, viewed in the direction of the longitudinal central axis of the fastening nail, is approximately 1 millimeter.
