The ACCIS prosthesis system
The ACCIS system for total hip arthroplasty (THA) and resurfacing hip
arthroplasty (RHA) consists of metal
components for the reconstruction of the acetabulum and metal femoral head
components for conventional
THA and RHA. The ACCIS metal components are made of a chrome-cobalt-molybdenum
alloy, but are different
from other metal-on-metal prostheses. The surfaces of the metal components are
engineered with the
ceramic Titanium-Niobium-Nitride (TiNbN) in order to minimize metal particulate
wear, to prevent corrosion
and to prevent metal ion release.
