文摘
The clinical experience with metal-on-metal hip arthroplasty now exceeds 40 years. Although some implants have survived with a remarkably low wear rate, others have failed because of flawed materials selection, poor manufacturing tolerances,inadequate clearance between implants, and impingement.Autopsy retrieval of implants that have survived long term has been invaluable in determining desirable features for a new generation of these implants.
High-carbon (>0.20% carbon) cobalt-chromium alloy has been demonstrated to have lower wear rates than low-carbon alloys. After investment casting of high-carbon cobalt-chromium alloy, large blocky carbides are precipitated throughout the metal matrix. These carbides are approxi-mately five times harder than the metallic matrix, approximately the same as alumina ceramic. A high carbide content confers wear resistance on a metal-on-metal articulation and is a desirable feature. Wrought material has a smaller grain size with a fine, homogenous distribution of carbides.
Diarnetral clearance refers to the gap between the two implants at the equator of the articulation and may be the most important variable affecting wear of the couple. Smaller clearances tend to produce fluid film lubrication and reduced wear. Inadequate clearance leads to equatorial contact between the implants, however, and the resulting high frictional torque may be responsible for the high loosening rate seen with some earlier-generation metal-on-metal implants. Conversely, too large a clearance leads to reduced surface contact, loss of effective lubrication, and more rapid wear.Current implants promote primarily polar contact with a clearance in the range of 100 to 200 μm, depending on the diameter of the head. With a monoblock metal acetabular component, elastic deformation occurring during implantation can reduce clearance.
This couple also has been described as "self-healing" because minor surface damage may be polished smooth over time. Hip simulator data and retrieval analysis have yielded combined wear rates less than 10 μm/yr for modern metal-on-metal articulations. Large-diameter heads (54 mm) have been associated with reduced wear. The particle size is much smaller than polyethylene, however, and the number of partides is larger.
Patients with metal-on-metal hip replacements have elevated levels of cobalt and chromium ions in serum, erythrocytes, and urine compared with patients with metal-on-polyethylene arthroplasties. The methods for measurement of these ion levels are complex, and there are no uniform standards for reporting. The long-term exposure to these ionsraises concerns of malignancies. In a long-term follow-up of 579 patients with metal-on-metal total hip replacements,Visuri et al. found no increase in cancer rates. A substantially larger series would be required to have the statistical power to rule out such an association, but at present there is no causal link between elevated metal ion levels and the development of malignancies.
