    Relations between tensile impact properties and microstructure of compact bone (1977)
    Springer
    Calcified tissue international 24 (1977), S. 65-72 
    Details
    ISSN: 1432-0827
    Keywords: Bone ; Strength ; Tension ; Microstructure ; Osteon
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine , Physics
    Notes: Summary Standardized human and beef femoral compact bone specimens were tested in tensile impact and the dynamic mechanical properties were determined. The microstructure of 45 beef and 47 human bone specimens were examined histologically to determine if there is a structural basis to account for strength differences in the bone samples. Strong negative correlations were obtained between the maximum stress and the percentage area of secondary osteons in each specimen. For human bone samples, the energy absorption capacity and the modulus of elasticity were also found to have strong negative correlations with the percentage area of secondary osteons present in each specimen. Linear regression equations were obtained describing the impact strength properties in terms of the percentage areas of secondary osteons and cavities in the samples. Fracture surfaces of the tested bone specimens were examined in a scanning electron microscope. Most surfaces exhibited a fairly rough texture indicating a quasi-cleavage type of failure. Fractographic analysis of bone fracture surface was helpful in understanding the micromechanics of bone fracture.

    Elastic and strength properties of canine long bones (1977)
    Springer
    Medical & biological engineering & computing 15 (1977), S. 72-74 
    Details
    ISSN: 1741-0444
    Keywords: Bone ; Elasticity ; Mechanical strength
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology , Medicine
    Notes: Summary The mechanical properties of canine long bones have been determined. The mean and standard deviation of the maximum load supported by six fresh canine femurs in 3-point bending was 1366±253 N. In all cases, the bones sustained a considerable amount of plastic deformation before failure. The modulus of elasticity (GN/m2), ultimate tensile stress (MN/m2) and yield stress (MN/m2) were 13·86, 108·3 and 88·3 for six humeral specimens and 13·88, 142·1 and 104·0 for 13 tibial specimens, respectively. The tibial specimens showed a statistically significant higher ultimate strength than the humeral specimens.

    Effect of various storage methods on the dielectric properties of compact bone (1988)
    Springer
    Medical & biological engineering & computing 26 (1988), S. 199-202 
    Details
    ISSN: 1741-0444
    Keywords: Bone ; Bone impedance ; Capacitance ; Dielectric properties ; Electrical properties ; Resistance ; Storage medium

    Notes: Abstract In the study the effects of vanous storage environments on the dielectric properties of bone were evaluated. Fresh cortical bone specimens from canine femora and tibiae were prepared and divided into three groups, with one group maintained at room temperature (24°C), a second group stored in a refrigerator at 3°C, and a third group stored in a freezer at ≈10° to −20°C. In each group, both the resistance and the capacitance decreased with time, the percentage change being largest for the samples stored in the freezer. This suggests that storage of bone specimens in a refrigerator or freezer with repeated thawing at room temperature does affect the dielectric properties of bone, the effect being dependent on the method of storage.
