Consensus statement "Current evidence on the management of metal-on-metal bearings"--April 16, 2012.

چکیده
a. What are the benefits (effectiveness)? MoM is currently the only technique for surface replacement. There are no polyethylene particles in pure MoM bearings that may cause osteolysis. MoM bearings produce less volumetric wear compared to conventional polyethylene. There is a reduced risk of fracture in MoM bearings compared to ceramics. Large head Total Hip Replacement (THR) (36mm head size and larger) as well as hip resurfacing have a reduced risk of dislocation compared to small head THR (2832mm head size). In large head THR range of motion increases with the head size (only up to 40mm). Hip resurfacing allows more preservation of bone stock on the femoral side when compared to conventional THR.

Metal-on-metal joint bearings and hematopoetic malignancy
This is a review of the hip arthroplasty era. We concentrate on new metal bearings, surface replacements, and the lessons not learned, and we highlight recent reports on malignancies and joint implants. A low incidence of blood malignancies has been found in bone marrow taken at prosthetic surgery. The incidence is increased after replacement with knee implants that release very low systemic le...
