Abstract
A locking mechanism for securing a bone screw to a clamping element of an osteosynthesis holding system is provided. The bone screw has a circumferential groove located on a top portion of the screw below a screw head Snap catches protrude from a bone-contacting surface of the clamping element and interlock with the groove in the screw when the screw is inserted into the clamping element (e.g., when the screw is screwed into a bone segment through a hole in the clamping element). A removal device is provided for removing the screw as a greater axial force is required to overcome the locking mechanism than is needed to engage the locking mechanism. A method for revision (removal) of the screw from the locking mechanism is also provided.
