Abstract: A fixing clamp for an aligning device, and an aligning device that includes the fixing clamp, for clamping to a bodily extremity. The clamp includes a first clamp arm, a second clamp arm and a frame device having an attaching section for attaching to an adjustment rod. The first clamp arm is rotatably attached to a first rotary joint about a first axis of rotation, and the second clamp arm is rotatably connected to a second rotary joint about a second axis of rotation. A locking mechanism locks the first clamp arm and/or the second clamp arm relative to the frame device in at least one position, and blocks movement of the first or second clamp arm about the respective rotary joint in an open rotational direction.

Abstract: The invention relates to a medical instrumentarium for implanting a hip joint endoprosthesis, which instrumentarium comprises at least one sawing template with at least one guide slot for a saw blade, wherein the sawing template comprises at least one first coupling element for temporarily coupling the sawing template to a second coupling element of a rasp body of a prosthesis rasp in a coupling position.

Abstract: The invention relates to a hip joint endoprosthesis system, comprising a medical instrument for extracting an implanted prosthesis stem of a hip joint endoprosthesis from a femur bone of a patient, which medical instrument has a coupling body with a coupling recess for accommodating a coupling cone protruding from the prosthesis stem, wherein the coupling body comprises a coupling base body and a coupling insert which is accommodated in a coupling insert receptacle of the coupling base body and defines the coupling recess.
