1. 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 connection,
wherein a mutual rotation of the elements along the shaft is adjustable and is blocked by means of an anti-rotation mechanism,
wherein, 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 means for blocking the rotation, wherein the rotation piece has two end faces, for the plug connection, and a jacket,
wherein a portion of the rotation adjustment device is configured to thread into a portion of the jacket.
