Primary Outcome Measures:
  • central BMD of the lumbar spine, proximal femur, total hip
  • peripheral BMD of the heel
  • results of texture analysis of the PIXI images
  • For assessment of bone turnover:
  • Bone Formation Markers
  • serum osteocalcin
  • BSAP as a markers of bone formation
  • Bone resorption Markers
  • urinary NTx and serum CTx
  • immunoradiometric assay

Ages Eligible for Study:   59 Years and older
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • The study will enroll 40 postmenopausal women with a T score < –2 either at the lumbar spine or the femoral neck: 20 who decide to begin anti-resorptive therapy (treated group), and 20 women who decline such therapy (control group). We will attempt to match the patients and the controls for T score (within 0.3) and age (within 5 years).
  • All study participants will be:

    • at least 3 years past the last menstrual period,
    • not on HRT, Raloxifene or calcitonin for at least 6 months.

Exclusion Criteria:

  • All study participants will not be on bisphosphonates during the previous 12 months.
  • Women with secondary causes of osteoporosis will be excluded.
