(iv) Metal-on-metal hip resurfacing

Current Orthopaedics, 2002
The 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, 1994
Abstract 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 ...

METAL/METAL ARTICULATING INTERFACES

Orthopedics, 1995
Polyethylene 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.

Metal-on-metal

The Bone & Joint Journal, 2013
Metal-on-metal bearing related issues in hip replacement and resurfacing continue to generate discussion, concern, audit and research as there are still many unknowns and clarity is required regarding the future implantation of such devices and the follow-up and investigation of patients with metal-

Assessing the Strength of Metal–Metal Interactions

Inorganic Chemistry, 2019
A 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 and metal–ligand bond strengths in metal carbonyl clusters

Coordination Chemistry Reviews, 2000
Abstract The limited experimental thermochemical information about metal carbonyl clusters, and the more extensive literature on structural studies of such compounds, provide a means of exploring trends in their stabilities. This review surveys that literature for selected metals, showing how the enthalpy of disruption of gaseous Mx(CO)y clusters ...
