Abstract

The invention relates to a hip prosthesis comprising a straight shaft (1) to be inserted into the femur. The proximal part (6) of said shaft to be inserted into the metaphyseal region of the femur comprises at least one projecting fin (8) having a medially steep flank (23) on the front and rear sides. Said fin (8) deviates away from the longitudinal direction (27) of the shaft (1) and is upwardly inclined towards the femoral neck (2), at least over part of its length. In this way, when the shaft is driven into the bone, the bone substance surrounding the fin (8) thickens and is able to absorb higher forces. The height of the fin (8) decreases from the medial flank thereof (23) to the lateral edge (25) thereof.

Claims (5)

1. A hip prosthesis comprising a shaft (1) which is to be inserted into the femur and whose proximal part (6) to be inserted in the metaphyseal region of the femur comprises, on the front face and rear face, in each case one projecting fin (8) whose medial flank (23) deviates away from the longitudinal direction (27) of the shaft (1) and at the top is inclined toward the femoral neck (2), characterized in that the medial flank (23) is steep, and the height of the fin (8) decreases in the lateral direction from the edge delimiting the steep flank (23).
2. The prosthesis as claimed in claim 1, characterized in that the fin (8) extends rectilinearly at an angle (alpha) of 5 to 15° with respect to the longitudinal direction (27) of the shaft (1).
3. The prosthesis as claimed in claim 1 or 2, characterized in that the height of the fin (8) above the surface (21) of the main body (22) of the shaft increases from the bottom upward.
4. The prosthesis as claimed in one of claims 1 through 3, characterized in that the height of the lateral edge (27) of the fin (8) is not greater than half the height of the medial edge (23).
5. The prosthesis as claimed in one of claims 1 through 4, characterized in that it comprises diaphyseal anchoring means.
