“…Identification of mechanical properties, such as elastic bone modulus can be done using several methods including mechanical testing [1][2][3][4], combination of lCT images with finite element modeling [5][6][7][8][9][10][11][12], and ultrasonography or acoustic microscopy [9,13].…”

The relationship between microarchitecture to the failure mechanism and mechanical properties can be assessed through experimental and computational methods. In this study, both methods were utilised using bovine cadavers. Twenty four samples of cancellous bone were extracted from fresh bovine and the samples were cleaned from excessive marrow. Uniaxial compression testing was performed with displacement control. After mechanical testing, each specimen was ashed in a furnace. Four of the samples were exemplarily scanned using micro-computed tomography (μCT) and three dimensional models of the cancellous bones were reconstructed for finite element simulation. The mechanical properties and the failure modes obtained from numerical simulations were then compared to the experiments. Correlations between microarchitectural parameters to the mechanical properties and failure modes were then made. The Young's modulus correlates well with the bone volume fraction with R² = 0.615 and P value 0.013. Three different types of failure modes of cancellous bone were observed: oblique fracture (21.7%), perpendicular global fracture (47.8%), and scattered localised fracture (30.4%). However, no correlations were found between the failure modes to the morphological parameters. The percentage of error between computer predictions and the actual experimental test was from 6 to 12%. These mechanical properties and information on failure modes can be used for the development of synthetic cancellous bone.

“…mFEA is a robust method to predict the linear elastic properties of human cancellous bone (Chevalier et al, 2007) and can be used as surrogate for destructive mechanical testing of real specimens (Niebur et al, 2000). Van den Bergh et al (2000) have compared experimental speed of sound with apparent Young's modulus obtained from mFEA and concluded that speed of sound reflects Young's modulus assessed by micro-structural finite element analysis. In the present work, the predictive value of BUA is also analyzed, which represents a progress compared to Van den Bergh's study.…”

“…In the present study, physically non-active but not active young Malay females and males were recruited. Nevertheless, we still observed the close relationships between bone health status reflected by tibia bone speed of sound values (Drake et al, 2002;Van den Bergh et al, 2000) and muscular strength reflected by knee muscular peak torque values.…”

Problem statement: Data on bone health status, muscular peak torque (an indicator of muscular strength) and power is still lacking in non-active young Malays. Moreover, no study has been undertaken to investigate the association between bone health and anaerobic capacity in the Malay population. Hence, the present study was designed to address the paucity of this information. Approach: Young, healthy Malay females (n=33) and males (n=33) university students aged 18-25 years old were recruited for this study. The quantitative ultrasound measurements of bone speed of sound (SOS) in the legs were measured using a bone sonometer. Muscular peak torque of knee extension and flexion at 60 0 .s -1 and 180 0 .s -1 were measured using a BIODEX isokinetic dynamometer. Anaerobic capacities of the participants were determined via the Wingate anaerobic test. Purpose: To investigate the relationships of lower limbs' quantitative ultrasound measurement of the bones with muscular peak torque and anaerobic capacities in Malay university students. Results: Correlation coefficient (r) between non-dominant tibial SOS and muscular peak torque at 60 0 .s -1 and 180 0 .s -1 in female participants was 0.448 (p=0.009) and 0.388 (p=0.026) respectively. In males, moderate correlation was found between nondominant tibial SOS and muscular peak torque at 180 0 .s -1 knee flexion (r=0.419, p=0.015). Conclusions: There were moderate correlations (p<0.05) between muscular peak torque, mean power and peak power in the male participants. Nevertheless, no significant correlations were observed between tibial SOS and anaerobic capacities of mean power and peak power in both females and males. There were moderate relationships between quantitative ultrasound measurement of the bones with muscular strength, but not with anaerobic capacities in university students.
