On the choice of the thickness of the cement mantle in cemented hip arthroplasty

Ievgen Levadnyi, Jan Awrejcewicz, Alexander Loskutov, Olga Szymanowska
Recommendations for the optimal thickness of the cement mantle in cemented hip arthroplasty
are outlined based on the results obtained with the finite element method. The
investigations show that distal femur cement thickness higher than 2mm positively affects
mechanical behaviour of the cement mantle and can be useful in reducing stress-strain levels
in the distal part of the femur what leads to prevention of development of a stress-shielding
effect. The results of the study can contribute to the success of long-term implants.
