Mini Stem
The humeral stem component is manufactured from Ti6Al4V alloy. The taper has a machine finish and accepts the taper adaptor of the humeral head component. The proximal region of the bone-contacting outer surface features a porous coating of plasma-sprayed titanium alloy, while the distal portion is polished. Seventeen stem diameters are available - 4 mm to 20 mm, in 1-mm increments.
Nano
The stemless humeral component is manufactured from Ti6Al4V alloy. It consists of a central tapered region and six outer wings. The taper has a machine finish and accepts the taper adaptor of the humeral head component. A small groove is included just below the taper to accept an inserter/impactor. The bone-contacting outer surface features a porous coating of plasma-sprayed titanium alloy for cementless fixation in the proximal humerus. Six sizes are available - 30 mm, 32 mm, 34 mm, 36 mm, 38 mm, and 40 mm.
