Abstract
The present invention relates a system to be used with an implanting tool having a tip part. The system has a longitudinal axis and comprises a polymeric screw () having a head () and an adapter between the screw () and the implanting tool. The adapter comprises a first part () which fits the tip part of the implanting tool. The first part comprises a first element and the system comprises a second element. The first element and the second element are connected to each other with a torque limiting junction having a first maximum torque when the screw is screwed in and a second maximum torque when the screw is screwed off. The shape of the first element and the second element is such that the second maximum torque of the torque limiting junction is greater than the first maximum torque, thus allowing the removal of the polymeric screw () from its position.
