The fremoral stem for total hip arthropathy

摘要

The present invention relates to a femoral stem for an artificial hip joint, more particularly, to actually insert during joint movement It relates to the interference and in contact with the neck portion cross-sectional area is removed by the processing method of the femoral stem for an artificial hip joint so as to maximize the range of motion while maintaining the maximum and the femoral stem in the femoral stem, which is toward the inside in the vicinity of the outer diameter 40 to 50 inclined cutting, and the cutting surface is symmetrical cutting is in contact with the virtual center of the inner diameter and the outer diameter of forming the same, the processing along the rounded inner diameter between the inside of the cutting face by more than the outer diameter of outer is achieved by machining to form short, the range of motion of the hip because of this many problems due to interference caused to existing small, for example, wear or breakage of the ceramic insert on the inside of the polyethylene cup, dislocation of the artificial joint, further It will have the effect of reducing dissociation of the artificial joint and the like.
