PCT No. PCT/SE87/00043 Sec. 371 Date Aug. 25, 1987 Sec. 102(e) Date Aug. 25, 1987 PCT Filed Jan. 30, 1987 PCT Pub. No. WO87/04612 PCT Pub. Date Aug. 13, 1987.A fixating device for fixating a femur fracture in the proximity of the hip joint, comprises an arcuate anchoring arm (17) which is intended to be inserted through an aperture formed in the wall of the femur and down in the femur and brought to an anchoring position therein. The arm merges at one end thereof with a guide part (15) provided with at least one guide hole (24, 25), with a fixating screw to be screwed into the neck of the femur. The anchoring arm (17) terminates in a free end (17A). The guide part (15) has an inwardly facing surface (15B) and an outwardly facing surface (15A), which touch respectively an inner plane (30), and outer plane (29). A center plane 31 lies approximately midway between and is parallel to the inner and outer planes and to the main longitudinal direction of the guide part. The anchoring arm has a convex outer surface tangential to a further plane (32) which is parallel to the other planes. A center part of the anchoring arm lies on one side of the inner plane (30) and the free end (17A) of the anchoring arm lies on the other side of the inner plane (30) and the further plane (32). Thus the convex outer surface and the free end of the anchoring arm are adapted to bear against opposite sides of the interior of a femur at regions spaced along the length of the femur. |
