Pre-augmentation Position 1, V=3mL Position 2, V=3mL Position 1, V=6mL Position 2, V=6mL Fig. 1: Cement distributions (left column) and the corresponding strength assessment indicator distribution (right column). Transparent and green areas refer to 0≤SAI≤1 whereas yellow and red areas refer to SAI>1, thus where the trabecular bone structure is at risk to fail.
Fig. 2: The relative overall organ strength improvement OSI as a function of the injected cement volume (left figure) and the cement type (right figure). A larger injection volume has a strong positive effect whereas the variation of the cement stiffness has only a marginal positive effect on the overall strength. 5. DISCUSSION AND CONCLUSIONS The aim of this study was to combine computational simulation techniques to model the mechanical effect of vertebroplasty and to assess the efficacy of the procedure using quantitative measures. The results presented support our hypothesis, that the efficacy is strongly related to the location of the injection site within the vertebral body. This statement is supported by the SAI-distributions in Figure 1. For treatment position 2, only 3 mL of cement injection is required to achieve approximately the same strength improvement that follows the treatment at position 1 with 6 mL cement. An important aspect is that the OSI-indicator, for some of the injection locations, indicates a negative procedure outcome, which should be avoided. The results in Figure 2 suggest that the injected volume should be as large as possible. This finding might be true from a mechanical point of view. However, a larger injection volume is also associated with a higher treatment risk (cement leakage, embolism etc.) and consequently shouldn’t be the optimization path to follow. Our findings fit within the conclusions drawn from the randomized controlled trials that support or question the efficacy of vertebroplasty. Critics would say that an improvement by vertebroplasty can only achieved by chance whereas the optimist argues that the uncertainty can be eliminated by optimization techniques. The computational model presented in this study is a first attempt to solve this optimization problem by considering the patient’s condition prior the treatment and sampling the (highly dimensional) solution space at uniformly distributed points. Besides the optimal treatment parameters, the presented measures allow to quantitatively judge the efficacy of the vertebroplasty according to the patient’s condition individually. At the moment, this model is limited to one spine level, and there is no evidence on the accuracy of the overall computational model. While there is an ongoing effort to experimentally validate the model and improve its accuracy, an extension towards a multi-level or full-body diagnosis tool can be achieved by incorporating it into a musculoskeletal simulation system.
