The white fluorescence of bone trabeculae was nicely contrasted to the blue-green fluorescence of the synthetic material, and on the distal side of each trabecula bone marrow spaces were apparent. 51. Wagner cup 2 years after surgery: the stiffened spongiosa has not only remained alive but also has not atrophied; it shows impressively that it can resist deformation. 52. Wagner cup 10 years after surgery: the areas where force was transmitted are stiffened and resistant. The unstiffened area has completely atrophied (stress shielding) giosa was fully intact and vital.

These studies generally measured only porosity (Haas et a1. 1975). Lee et a1. (1973) found a decrease in strength dependent more on stirring (revolutions per second) than on the duration of the mixing. Changing the speed of rotation during mixing had not been studied. Eyerer and Jin (1986) concluded that a short mixing time with low speed of stirring gave the best results. Studies of such an approach in our institute resulted in inhomogeneous mixtures. The two parameters, homogeneity and porosity, had to be analyzed separately.

In addition, standard viscosity bone cements have a number of advantages which make them superior to the low viscosity group (Table 2). The low viscosity bone cement might be conflicting with respect to the tolerance of the applicating procedure. This is due to the fact that it is liquid over a long 46 Chapter 6 Preparation of the Bone Cement Fatigue trel1gth low viscosity bone cement Standard viscosity bone cement + ++ +++ ++ +++ + ++ lbierance of the procedure Avoidance of intermixing Vacuum mixing + Pushing a ide bone marrow Storage at 4"C Curve of polymerization period of time and is intermixed very quickly by blood during that time.
