In a retrospectic study of 41 women over 60 years of age, 38 of them had a BMD below - 1 SD of the total skeleton. Body composition obtained by DXA was reanalyzed. Eleven of these patients had suffered an osteoporotic fracture (6 vertebral, 4 non vertebral and 1 both). The results of the whole group were: Age 75 ± 8 y.o., body mass index (BMI) 25.4 ± 4.0 kg/m², fat mass (kg) 24.1 ± 6.9, lean mass (kg) 34.1 ± 3.4 and total skeleton T-score -2.03 ± 0.82. Apendicular (aMM) (kg/m²) 5.99 ± 0.72. Arms MM (arMM) (kg/m²) 1.44 ± 0.21 and legs MM (lMM) (kg/m²) 4.55 ± 0.6. The T-score of the aMM was -1.16 ± 1.03. aMM had a significant correlation with lean mass (r= 0.63; p< 0.001 ) but a weak correlation with fat mass (r= 0 .42;p
