Delta Classic Stem
Femoral Hip System
Product Overview
- Ti6Al4V material with Ti+HA dual coating (225ym pure titanium coating + 70um hydroxyapatite coating per side) ensures long-term bone ingrowth
- Proximal rectangular cross-section resists axial and rotational stress, ensuring initial stability
- Lateral shoulder cutting design makes implantation smoother
- Proximal stepped design optimizes stress distribution, converting ring shear stress to axial compressive stress, improving axial stability
- Distal vertical and horizontal grooves provide rotational and axial stability
Special Description
The reduced lateral shoulder eases stem insertion
Rectangular cross section design resists axial/torsional stresses for initial stability
The proximal steps designed to convert hoop stresses to compression loads to avoid intra-operative fracture, and provide consistent implant seating height and initial stability
Distal vertical/horizontal grooves provide rotational and axial stability
Optimal offset aiming to restore hip biomechanics Ti6Al4V material and Ti+HA double layered coating (225 micron Ti coating plus 70 micron HA coating) ensure long-term bone ingrowth
Proximal stem stepped design
Optimizes stress distribution by converting circumferential shear stress to axial compressive stress, enhancing axial stability
Distal stem vertical / horizontal groove design
Provide rotational and axial stability
Side shoulder cutting design
Easy implantation process
Base material:
TC4, Ti + HA double coating
Ti coating thickness: 225 µm
HA coating thickness: 70 µm
Excellent long-term bone ingrowth
