Recent studies have highlighted significant risks associated with metal-on-metal (MoM) hip joint replacement,1 leading Smith a al2 to recommend that research should be 'focused on understanding the biological consequences of exposure to orthopaedic metals'. One of these consequences may be the development of solid or fluid-filled inflammatory lesions, termed pseudotumours, which have been reported in areas around MoM joints.The articulating surface of MoM joints is fabricated from a hard alloy containing approximately one part chromium to two of cobalt. Ionic forms of both these metals can be detected at a high level (<5 mM Cr, 展开▼
