摘要: Photon absorptiometric (125I) bone mineral assay and low strain-rate axial compression tests were carried out on cylindrical cancellous specimens from the proximal tibial epiphysis of large, skeletally mature mongrel dogs. Bone was reproducible within ±5.0 per cent (99 tolerance limits). Linear regression analysis with concentration as independent variable showed a strong correlation towards ultimate strength (r = 0.92) yield 0.89), somewhat weaker elastic modulus 0.82), energy absorption 0.79), 0.73), insignificant strain −0.14) −0.18). The power relationships between trabecular density compressive suggested by Carter Hayes (1977) not statistically superior to linear in relatively narrow range reported here. quadratic relationship betwee...
