Osteoporosis in adults in clinical practice (1): diagnosis and differential diagnosis.

Abstract

Osteoporosis is a systemic metabolic disease of the skeleton characterized by low bone strength that results in an increased risk of fracture. Fractures are associated with serious clinical consequences, including pain, disability, loss of independence, and death, as well as high healthcare costs. Early identification and intervention with patients at high risk for fracture is needed to reduce the burden of osteoporotic fractures. The identification of a patient at high risk of fracture should be followed by evaluation for factors contributing to low bone mineral density (BMD) and/or low bone quality, falls, and fractures. Components of the osteological evaluation include an assessment of BMD by dual-energy X-ray absorptiometry, osteoporosis-directed medical history and physical exam, laboratory studies, and possibly skeletal imaging. Disorders other than osteoporosis, requiring other types of treatment, may be found. This overview summarizes the basic procedures for the diagnosis and differential diagnosis of osteoporosis, which are necessary before starting treatment.
