¡ñ The larger funnel index
makes the stem match the distal part of the femur better.
The larger eccentricity can release the rotating center
of the acetabulum better. All these will make the hip
joint more stable.
¡ñ The proximal part of the
stem is designed in a near rectangle shape:
¡¡*The morrow cavity is not
fully occupied, so as to guarantee the supply of blood
to the morrow cavity. It is favorable to the in-growth
of bone.
¡¡*It is of good property
of anti-rotation.
¡ñ The principle of fixation
at the proximal part has been adopted. The 1/3 part of
the stem at the distal end is polished so as to decrease
the pain in the thigh caused by the stress at the stem
tip.
¡ñ Optimized surface coating
¡¡*The surface of the cylindrical-shape
stem is first sandblasted by carborundum and then is treated
with HA coating. On the 2/3 surface of the stem on the
proximal part, is coated with HA with a thickness of 80~100
¦Ìm. This will guarantee the maximum strength and firm
fixation between the prosthesis and HA coating, effectively
preventing exfoliating of the HA coating and the too early
absorption of the HA.
¡ñ The taper is designed in
internationally accepted standard of 5¡ã43¡ä30¡å, which is
self-locking.
¡ñ
All the packages are imported, which makes the sealing
effective, safe and sound.

European-style stem with double taper in design
¡¡*On the front and lateral
surfaces, from the proximal end to the distal end, double
taper is designed with tight press-fit assembly. As a
result, bone support in large area is realized.
¡¡*Better stabilization of
anti-rotation
¡¡*Smaller stress at the distal
end
¡ñ The upper part
of the stem is designed with patented texture of fish-scale
pattern, which can effectively prevent the sinking and
rotation of the stem.
¡ñ
The cross section of the stem is designed in the shape
of rectangle£¬as a result, the marrow cavity is not fully
occupied. This can guarantee the blood supply to the marrow
cavity and do good to the bone growth, preventing the
rotation of the stem.
¡ñ
The whole stem is covered by HA coating with a thickness
of 80¡«100¦Ìm. This coating will cultivate the bio-compatibility
and is favorable to the bone ingrowth.
¡ñ
The stem is designed in two kinds, with or without collar,
satisfying different needs of the customers.
¡ñ
It is packed in fine package. All the packages are imported.
