In general, one would expect higher release of cobalt and chromium from resurfacing, with a relatively large articulating metal-on-metal bearing, as compared to a regular metal-on-metal hip arthroplasty, but there have been no conclusions in the literature about this issue (Smith et al. 2001).
Over 80% of artificial hip joints utilise polyethylene acetabular cups articulating on metal or ceramic femoral heads.
Metal-on-metal articulating total joint arthroplasty has the potential to eliminate polyethylene-wear-induced osteolysis and aseptic loosening around the prosthesis.
Testing S-phase against S-phase is both scientifically interesting and technologically important in view of their potential applications for the articulating surfaces of metal-on-metal joint prostheses.
One of the potential disadvantages levelled against dual-mobility articulation is the theoretical increased risk of polyethylene wear, because both the concave and convex surfaces of the polyethylene liner articulate with the metal components.
The concept of a dual-mobility hip socket involves the standard femoral head component encased in a larger polyethylene liner, which in turn articulates inside a metal shell implanted in the native acetabulum.

Upon thorough debridement of the affected area, static spacers containing antibiotic-loaded bone cement, or articulating spacers with a metal femoral component were inserted.
In 1953, the McKee 32-mm metal head articulating against a metal cup (MOM) made of cobalt-chromium was introduced (McKee and Watson-Farrar 1966).
This has also been reported in the Australian joint registry, where revision rates of THRs with ceramic and metal heads articulating on modified PE have been compared; results with conventional PE have not been compared (Graves 2011).
He has bought 26 skulls so far, along with two skeletons: one fully articulated, pieced together with metal wire, and one disassembled.
