“…22 The results obtained indicate that the plasticizing effect of water seems to counteract the embrittlement produced by the residual monomer loss, which is greater in an aqueous medium at 37°C than it is in air at room temperature. 23 These results seem to be consistent with the work of Freitag and Cannon 24 who found that the fatigue life of acrylic bone cement is enhanced when the test is run in an aqueous medium at body temperature.…”

The aim of this study was to investigate the effect of adding an elastomeric second phase, acrylonitrile-butadiene-styrene, on the fatigue crack propagation behavior of poly(methyl methacrylate) bone cement. Moreover, the influence of porosity and environmental conditions was studied. When comparing the plain cement to the modified cement, a decrease in the crack propagation rate was observed at between 1 and 2 orders of magnitude. The storage in a physiological environment (saline solution at 37 degrees C) also caused a decrease in the crack propagation rate of about 2 orders of magnitude for the plain and modified cement prepared in air or under a vacuum. Porosity did not have any noticeable effect on the fatigue crack propagation behavior of the cement.

“…Five systematic studies on this aspect have been reported 9,47,69,77,81,86 (Table I). Freitag and Cannon 9 found that, for Simplex P specimens tested in air at 22°C, the fatigue life of the radiopaque cement was between 1.5 and 3 times that of the radiolucent variant (depending on the pressure applied to the polymerizing cement dough during molding of the test specimens).…”

Over the past three decades or so, a very large volume of literature has been generated on the impact of an assortment of variables on the fatigue lifetimes of a large number of acrylic bone-cement formulations. In the present article, this literature is examined critically to reveal areas of agreement, areas of disagreement, as well as a welter of underexplored and unexplored topics. For example, there is unanimity of support for the notion that an increase in the molecular weight of the powder constituents or the fully cured cement leads to an increase in the cement's fatigue life, whereas there is disagreement as to whether vacuum mixing the cement constituents leads to an increase in the fatigue life of the fully cured cement (relative to the hand-mixed counterpart). Among the underexplored topics is systematic study of the effect of test frequency on the fatigue results, whereas determination of the optimal concentration of the antibiotic in an antibiotic-loaded cement is an example of the unexplored topics. It is pointed out that resolving the controversies, addressing the underexplored topics, and filling the lacunae will allow comprehensive evaluations of acrylic bone-cement materials to be made. This enhanced body of knowledge will prove invaluable in the continued use of acrylic bone cement as the anchoring agent in cemented arthroplasties.

“…A sinusoidal uniaxial zerotension loading was applied at a frequency of 4 Hz, this type of loading being chosen because it represents a critical condition for the accumulation of fatigue damage found in vitro and in vivo (Gates et al 1983, McCormack et al 1996. The test environment was air at 23°C, representing an environmentally critical condition in terms of bone cement fatigue testing (Freitag andCannon 1977, Nguyen et al 1997). Tests were done at 6 stress levels (9.0, 10.5, 12.0, 13.5, 15.0 and 16.5 MPa) and 2 specimens of each material were tested at each level.…”

Mechanical effects of the use of vancomycin and meropenem in acrylic bone cement

et al. 2006

Background The increasing resistance of certain bacteria to antibiotics commonly used in bone cements has led to a demand for alternative antibacterial agents. The antibiotics added to bone cements may, however, have detrimental effects on the mechanical properties of the cement.Material and methods We evaluated the mechanical effects of adding vancomycin and meropenem to bone cement by compression, bending and fatigue tests.Results Addition of vancomycin at a concentration of up to 2.5% (w/w) had no effect on the compressive strength. Bending and fatigue strength were negatively affected by vancomycin but not by meropenem.Interpretation A cement containing 1.25% vancomycin and 1.25% meropenem might be an interesting compromise between the introduction of antibacterial properties and preservation of the mechanical properties. With this concentration of additives the compressive strength and the fatigue strength remain unchanged, while the bending strength (-14%) and the bending modulus (-9%) are only slightly reduced and remain above the limits set by the ISO5833 standard.
