“…One well-known solution, especially in the case of dental and bone cements, is the incorporation of inorganic additives, such as barium sulphate or zirconium dioxide particles. In the case of methacrylic bone cements, it has been reported that these particles diminish the mechanical properties (especially fatigue life) due to the creation of interfaces between the polymeric matrix and the inorganic radio-opacifying particles [1,[7][8][9][10][11][12]. In addition, the release of such particles has been found to be deleterious to bone since they activate bone resorption [13].…”

“…In other words, the interaction effect is determining when these two defects are located too close one to the other. This too fast increase of this factor leads to the interconnection of these two cracks and thus to their coalescence, phenomenon observed experimentally (Figure 1) [8]. This observation clearly shows the risk of interconnection is all the higher than the cavities are located very close one to another.…”

“…Three selected load cases were used with an average body weight of 70 kg assumed. The sacroiliac joint was fully fixed while the pubic joint was allowed to in sagittal plane, boundary conditions considered to be representative of anatomic configuration (Figure 2a) [8,9]. The contact between bone and cement and between cement and cup was taken as fully bounded, and between femoral head and cup was assumed to be frictionless under small sliding condition.…”

In this study, we use the finite element method to analyse the behaviour of cracks emanating from microcavities in the bone cement, binding the cup to the bone, according to their size and position around the cavity, the position of the patient, the cavity's location and the inter-defects distance (cavity-crack, crack-crack). We show that the most unstable stress intensity factor, in mode I, when the crack located in the cement's centre and propagating along this thickness. This instability is all the more important that its size increases, tends towards the cavity, the cracks are located in a vicinity one to other and that the patient is in a squatting position. The predominant fracture mode, in mode I and II, depends on the crack's position priming site around the microcavities. This work allows the better understanding of the interconnection phenomena of the microcavities experimentally observed.

“…One must also note that ZrO 2 exerts a more pronounced effect on the temperature profile than BaSO 4 , which can be explained in terms of the thermal properties of the fillers. It must be pointed out that these radiopaque contrasts have been shown to impart different mechanical properties to the final bone cement pieces, as presented in the open literature (e.g., Hass et al, 1975;Bhambri and Gilbertson, 1995;Molino and Topoleski, 1996;Vazquez et al, 1997;Ginebra et al, 2002;van Hooy-Corstjensa et al, 2004). …”

-The present work concerns the preparation of bone cements based on poly(methyl methacrylate) (PMMA), used mainly for prosthesis fixation and cavity filling for correction of human bone failures. A typical bone cement recipe contains methyl methacrylate, which polymerizes in situ during cement application. An inherent problem of this reaction is the large amount of heat released during the cement preparation, which may lead to irreparable damage of living tissues. Optimization of PMMA-based bone cement recipes is thus an important step towards safe and reliable clinical usage of these materials. Important process variables related to the reaction temperature profile and the mixing of the recipe constituents were studied in order to allow for the adequate production of bone cements. It is shown that the average molar mass and size of the PMMA particles used in the production of the bone cement, as well as incorporation of radiopaque contrast, co-monomers and fillers into the bone recipe play fundamental roles in the course of the polymerization reaction. Furthermore, the injection vessel geometry may interfere dramatically with the temperature profile and the time for its occurrence. Finally, it has been observed that the morphology of the PMMA particles strongly affects the mixing of the bone cement components.
