The analysis of hip compression screws made of implant steel under static and limit load requirements

Abstract

The load capacity of rigid and adjustable built hip compression screws (HCS) made of implant steel X2 CrNiMo 18 15 3 (DIN 17443) were laboratory tested at room temperature and randomly examined. The HCS were also put through experiments with cyclic limit bending loads until failure. HCS implanted for the stabilization of a femoral fracture load requirement. The load level was determined by the transverse load F2 resulting from the hip load R as shown in Figure 2.1.
