Inclusion Criteria

. Women of at least 50 years
. Postmenopausal for at least 3 years
. Osteoporotic:
- T-score at the L1-L4 spine and /or Femoral Neck less than or equal to -2.5 SD, corresponding to a lumbar mean BMD of all assessable vertebrae between L1 and L4 less than or equal to 0.772 g/cm² and/or a femoral neck mean BMD less than or equal to 0.572 g/cm² for Hologic apparatus, or corresponding to a lumbar mean BMD of all assessable vertebrae between L1 and L4 less than or equal oto 0.880 g/cm² and/or a femoral neck mean BMD of less than or equal to 0.680 g/cm² for LUNAR apparatus .
or
- T-score at the L1-L4 spine and /or Femoral Neck of less than or equal to -1 SD and at least one prevalent low trauma fracture, corresponding to a lumbar mean BMD of all assessable vertebrae between L1 and L4 less than or equal to 0.937 g/cm² and/or a femoral neck mean BMD less than or equal to 0.738 g/cm² for Hologic apparatus, or corresponding to a lumbar mean BMD of all assessable vertebrae between L1 and L4 less than or equal to 1.060 g/cm² and/or a femoral neck mean BMD less than or equal to 0.860 g/cm² for LUNAR apparatus .
At least 2 vertebrae must be assessable between L1 and L4; if less than 2 vertebrae are assessable, the T-score will be considered only at the Femoral Neck.
