The range is scaled from 2 mm to 2 mm, ranging from size 46 to 64 mm. The ATLAS metal-back is complemented by a wide range of highly cross-linked polyethylene liners (TRIANON), available in different internal diameters (28, 32 and 36 mm) and different shapes (flat edge and rear wall).

The ATLAS metal-back is made from a TA6V4 ELI titanium alloy with a constant thickness of 2.5 mm, with a hydroxyapatite coating. Highly cross-linked polyethylene liners, called TRIANON, are available:

• in 28 mm from size 46 to 64 mm,
• in 32 mm from size 50 mm to size 64 mm,
• in 36 mm from size 54 mm to size 64 mm.

The ATLAS instrumentation is an instrumentation common to the different types of cups in the FH ORTHO range. This ancillary allows all classic approaches including minimally invasive approaches. It is supplemented by optional spacer baskets.
