Revision of Metal-on-metal Hip Arthroplasty with Well Fixed
Objective:
(1) What clinical problems have been reported in patients with Metal-on-metal hip arthroplasties?
(2) Could the tribocorrosion potentially cause a fracture of neck femoral component?
(3) Can be the dual-mobility head a recourse in metal-on-metal hip revision?

Methods:
Ten patients were revised for pain or/and raised Cobalt/Chromium levels between August 2012 and December 2015. In three cases femoral neck component was fractured and femoral revision was necessary. In four hips, acetabular and femoral components could be maintained. Age, body index mass, ion levels, acetabular position, size of acetabular component and femoral head, approach, blood transfunsion and time of hospitalization were analized....
