Introduction
Osteopenia is a general term for low bone mass.
Etiology
- osteoporosis*
- primary
- postmenopausal (I)
- senile (II)
- idiopathic in younger men & women
- Secondary
- primary
- Cushing's syndrome (includes glucocorticoid therapy)
- hyperthyroidism
- hypogonadism in men
- immobilization
- chronic illness & lack of exercise[6]
- chronic heparin administration
- osteogenesis imperfecta
- Primary hyperparathyroidism
- Osteomalacia
- Myeloma
- Mastocytosis
- Renal osteodystrophy
* minimal trauma fracture makes diagnosis of osteoporosis
Radiology
- bone mineral density (T-score -1 to -2.5)
- repeat in 2 years if osteopenia not reaching criteria for treatment with bisphosphonate[5]
Management
- calcium 1200 mg/day for men & women > 50 years preferably from dietary sources & vitamin D 600 IU/day, 800 IU/day recommended for elderly > 71 years[6]
- alendronate reduces vertebral fractures with osteopenia at the femoral neck[2]
- not cost-effective when only risk factors for fracture are age & bone mineral density[3]
- initiate bisphophate treatment in postmenopausal women & in men age >= 50 years with low bone mass (T-score -1 to -2.5, osteopenia) at the femoral neck, total hip, or spine & 10-year hip fracture probability >= 3% or a 10-yr all major osteoporosis-related fracture probability of >= 20% based on the FRAX fracture risk assessment tool[4][5]
- FDA approves vibrating belt to help women[7]
