Excellent initial stability:
Clinical studies have shown that the coefficient of friction of the highly porous surface of the trabecular cup is 40%-75% higher than that of the conventional coated cup.
JUST 3D SEE® trabecula metal cup and trabecular sleeve use electron beam melting (EBM) process for high surface roughness, 75%-80% porosity design, friction coefficient up to 1.08, to provides excellent initial stability.
The JUST 3D SEE® trabecular metal modular femoral stem’s stem body is assembled with different types of trabecular sleeves for proximal intramedullary filling for superior initial stability.
Excellent bone ingrowth
The metal surface coating technology can effectively improve the bone ingrowth of the interface between the prosthesis and the host bone. At the same time, there are some potential risks such as shedding, poor thickness uniformity.
JUST 3D prints the trabecular structure is integrally formed by EBM technology. The metal particles are completely fused, and the porous layer and the solid have no interface, avoiding the risk of surface detachment and facilitating long-term osseointegration.
Pore diameter: The diameter of the inscribed ball of the trabecular element structure. Clinical studies have shown that a pore diameter of >300 μm is conducive to the formation of new bone and vascularization.
Acetabular up and trabecular sleeve are selected for a 600-800 μm pore diameter to perfectly balance the bone ingrowth performance and mechanical properties of the prosthesis.
Porosity: refers to the ratio of the pore volume in the material to the total volume of the material in the natural state. This parameter is related to the pore size in the surface of the prosthesis, the thickness of the beam and the shape of the pore. The porosity of human cancellous bone is 50%-90%, and the porosity is considered to be the most favorable for bone growth in this interval.
The JUST MED’s 3D SEE® trabecular metal cup and trabecular sleeves are 75%-80% porosity for great bone ingrowth.
Three-dimensional communication micropores: Conducive to the growth of bone tissue to the center.
P.S.: JUST 3D-printing raw materials use titanium metal powder imported from Sweden to strictly control the source of the material.
