RSL Cementless Revision Femoral Stem
Product Details
- Biological fixation in solid bone
- lmmediate distal anchorage on the old bone bed
- Initial stability is obtained by press-fitting
- Secondary stability through osseointegration
- Longitudinal ribs ensure rotational stability
- Tapered design avoids sinking
- Anchoring length: min 7 cm, best 10 cm
- 4 lengths and 30 sizes to address a wide range of revision patients
8 Longitudinal Ridge Design
Resists rotational stress, reduces stem thickness to decrease stiffness, increases contact area, enhances immediate stability
2° Taper Design
Even stress distribution, enhancing immediate stability
Integrated & Rough surface design
Ensures femoral stem strength (not easily fractured), improves safety.
Increases surface roughness and enhances immediate stability, optimizes microstructural mechanics, improves long-term bone integration.
Round Cross-Section Design
Allows free adjustment of anteversion angle;
no edges, avoids stress concentration.
Ti6Al4V (TC4) Material
Reduced Stress Shielding: TC4 has a lower elastic modulus, closely matching the human skeleton, minimizing stress shielding.
Enhanced Biocompatibility: TC4 offers superior corrosion resistance and cytocompatibility, promoting osteoblast function and cell differentiation.
Neck High-Polish & Proximal Binding Hole Design
Reduce the possibility of detritus generated by friction between the neck of the femoral stem and the acetabular side.
Fixes size for greater control over bone fracture
