ABSTRACT:
To hold mating bone parts or sections together during osteosynthesis, the ends of a piece of wire for holding the bone parts together are passed through narrow boreholes of one or more plates and are deformed at that section to retain them in the boreholes. The wire is subjected by means of tightening means to a desired tractive force and is deformed by means of deformation means. The tightening means and the deformation means cooperate to place the wire under traction and deform the same where it issues from the boreholes in the plate or plates. The deformation means operate like pliers in which the tightening means is located. The tightening means incorporates a shaft which can be driven with an adjustable torque and, by means of a freewheeling coupling, the shaft is mounted in a manner so that it can be rotated only in one direction.
