Minimal Bone Loss
Thank`s to the proximal anchorage of the stem in the methaphysis of the femur only a minimum of bone has to be sacrified.
Physiologic load transmission
The BreXis short-stem transmits loading forces in the naturally loaded region of the femur; anatomically and physiologically correct, following the trabecular structures and complying with Wolff`s law, forces are transmitted from the femoral neck in the methaphysis.
Safety against subsidence and high rotational stability are key factors for the success of a femoral neck prosthesis. The BreXis short-stem is tapered in axial direction in order to achieve a maximum of axial stability. The macro-structure on the anterior and posterior surfaces increases the contact area and safety against subsidence. The strongly trapezoidal cross-section makes no compromise in terms of rotational stability and maximizes the rotational safety.
Biocompatibility and osseointegration
The biocompatible and well approved titanium-vanadium-alloy is being used as base material of the BreXis short-stem. An additional porous titanium-hydroxylapatite coating in the proximal region increases the osseo-conductive ability and provides the basis for an optimal longterm-stability.
Polished is brilliant in use
The neck of the prosthesis is polished in order to achieve an even higher durability of the already highly durable titanium-forged alloy. The distal end of the prosthesis is polished as well, therefore avoiding bone ingrowth and minimizing “prosthesis-tip-pain”.
