Abstract
A medical device for fixation in a femoral bone of a patient is provided, the medical device comprises: a connecting portion adapted to be connected to a prosthetic hip joint contacting portion, an expanding portion, and a bone contacting surface on the expanding portion. The expanding portion could be adapted to be at least partially inserted into the femoral bone of a patient and to expand within the femoral bone, such that the bone contacting surface is placed in contact with the inside of the femoral bone for fixating the medical device to the femoral bone. By the fixation using an expanding portion a sturdy fixation is achieved without the need to go into or penetrate bone, or the need for fixation using bone cement.

A medical device for fixation in a femoral bone (7) of a patient, the medical device comprising:
- a. a connecting portion adapted to be connected to or integrated in a prosthetic contacting portion;
- b. a plurality of expanding portions having a bone contacting surface, wherein the expanding portions are adapted to be at least partially inserted into the femoral bone of a patient and to expand within the femoral bone such that the bone contacting surface is placed in contact with the inside of the femoral bone for fixating the medical device, directly or indirectly, to the femoral cortical bone;
- and
- c. a stabilizing member having a clasping portion adapted to be placed in contact with an outer surface of the femoral bone and operable for adjustably exerting a radial clamping force on the outer surface of the femoral bone for fixating the medical device to the femoral bone.
A method for mounting medical device for fixation in a femoral bone of a patient;
- the method comprising:
- a. cutting a skin portion of the patient,
- b. dissecting a hip region of a patient,
- c. surgically affecting and open the femoral bone,
- d. inserting an expanding portion of the medical device at least partially into the femoral bone,
- e. expanding the expanding portion within the femoral bone, such that the bone contacting surface is placed in contact with the inside of the femoral bone for fixating the medical device direct or indirect to the femoral cortical bone, and
- f. fixating the medical device to the femoral bone with a stabilizing member having a clasping portion being placed in contact with an outer surface of the femoral bone.
