T-value: comparison of bone mass density reference values between patients and young people of the same gender and race. P-value: T-test of death group and survival group. BMI: body mass index, CCI: Charlson comorbidity index score, E-PASS: estimation of physiologic ability and surgical stress; NHFS: Nottingham fracture score
