Abstract
The invention relates to an endoprosthesis shaft system for elongate bones, comprising an anchoring part () and a shaft (), which is formed from module elements that can be coupled by means of a plug-in connection (), wherein a mutual rotation of the elements along the shaft () is adjustable and is blocked by means of an anti-rotation mechanism. In order to adjust the rotation, a rotation piece () is provided as a further module element, which has a self-contained rotation adjustment device () and a clamping device () as a mechanism for blocking the rotation. The rotation piece () comprises two end faces for the plug-in connection () and a sleeve (). The invention provides, with the rotation piece, a particular module element for the shaft, which as a structural unit allows both an adjustment of the rotation and a blocking against undesired rotation in a self-contained unit.
