FIG. 1 shows an inventive implant 1. It has a central fillet 2 extending along a longitudinal axis L. The fillet 2 has openings 3 which are formed at regular intervals. At the level of the openings 3 and extending at right angles on both sides are clamps 4, which, when the implant is inserted, are brought into mutual engagement with a tubular bone and clamped to it. The fillet 2 is formed so as to be bendable in three-dimensions. It can be bent in two planes relative to the longitudinal axis L of the fillet 2 and torqued about the longitudinal axis L. Thus, a simple implant 1 with an overall regular structure is provided which can be cut with a cutting pliers to a desired length.
