Six groups of histogram specimen mechanical parameters. a For each set of elastic modulus, the elastic modulus at maximum is the upper edge of lamina. b For each set of elastic strain, ultimate strain at maximum is the inferior articular process. c The ultimate strength at maximum is the inferior articular process. d The maximum load at maximum is the inferior articular process
