Metal allergy and second‐generation metal‐on‐metal arthroplasties
Contact Dermatitis, 2011There are concerns about the induction of metal allergy with second‐generation metal‐on‐metal prostheses, and the role that this may play in the development of complications such as ‘pseudotumours’ or failure of the implant. In this review, we attempt to set out the current knowledge on this subject. From a review of the literature, it is apparent that

(iv) Metal-on-metal hip resurfacing
Current Orthopaedics, 2002The management of an arthritic hip in young active Patients represents a challenge to the treating orthopaedic surgeon. Results of the conventional hip arthroplasty in male patients under 55 have bee shown to approach 70% survivorship at 10 years,(1) Hip resurfacing has many theoretical advantages including bone preservation, reduced risk of ...

Metal—lingad and metal—metal coupling elements
Journal of Photochemistry and Photobiology A: Chemistry, 1994Abstract The electronic matrix element coupling a ground and charge-transfer excited state can be calculated from the energy intensity of the appropriate charge-transfer transition. An expression for the electronic coupling element widely used for this purpose is based on equations derived by Mulliken and Hush for an effective two-state model and is ...

Assessing the Strength of Metal–Metal Interactions
Inorganic Chemistry, 2019A proper comparison between bond strengths of different atom pairs is relevant only for the same formal bond order (BO) of atomic interactions, e.g., for single bonds, because it is clear that the higher is the BO or the number of the electron pairs responsible of bonding, the stronger is the bond. For the metal-metal interactions, such a comparison of

METAL/METAL ARTICULATING INTERFACES
Orthopedics, 1995Polyethylene wear can be shown as a problem in long-term joint replacement. Metal-on-metal bearing is solving this problem, as long-term clinical and experimental investigations demonstrate. To avoid the problem of high friction found in old series, a new Metasul called technique with a smaller diameter was invented.
