Influence of geometry and materials on the axial and torsional strength of the head-neck taper junction in modular hip replacements: A finite element study

- A three dimensional finite element model of head-neck taper junction was developed.
- Cobalt/Titanium taper junctions have longer contact lengths than Cobalt/Cobalt.
- Mismatch angle in the taper plays an important role in the strength of the junction.
