Abstract
The plug (,) comprises two coaxial parts (,) separated by a fracture initiating line (,). A respective print (,) is provided on each part and is coaxial with the other print. The first part (,) permits the screwing of the second part (,) which is provided with a screw thread (,) in an implant to which it must remain fixed after fracture of the two parts on the line (,), when a predetermined fracture torque is exceeded. The print (,) of the second part (,) permits a subsequent unscrewing, if necessary, for disassembling the instrumentation, which constitutes an essential advantage of this plug. Further, the clamping can be achieved with high precision in conformity with the wishes of the manufacturer, since the fracture torque can be adjusted to the intended value by machining the fracture intiating line (,) in a precise manner.
