Laser engravings as reason for mechanical failure of titanium-alloyed total hip stems
Two revisions of broken β-titanium total hip stems had to be performed in our hospital after 2 and 4 years in situ. Since both fractures were located at the level of a laser engraving, a failure analysis was c...

How stiffness and distal interlocking of revision hip stems influence the femoral cortical strain pattern
Stress shielding and nonphysiological load transfer after primary or revision total hip replacement (THR) prepare the ground for resorptive bone remodeling. The quality of the bone stock influences the risk of...

Differences between the wear couples metal-on-polyethylene and ceramic-on-ceramic in the stability against dislocation of total hip replacement
After total hip replacement an insufficient range of motion (ROM) can lead to contact between femoral neck and rim of the cup (=im**ement) causing dislocation and consecutive material failure. The purpose of...
