title: The diagnosis of osteoporosis.
abstract: A rational approach to the diagnosis of osteoporosis by the primary care physician is outline, with emphasis on the patient who presents with chronic back pain and a vertebral compression fracture. The basic information includes data from the patient's history and physical examination, laboratory, x-ray and bone biopsy studies, and determination of bone mineral content (BMC) by photon absorptiometry. Characteristic radiologic features associated with bone loss, BMC changes, and bone biopsy findings are illustrated. This diagnostic approach, summarized in a flow diagram, poses a series of questions; the answer to each question leads either ot a diagnostic conclusion or to further questions which must be answered. This permits decision as to whether a compression fracture is due to trauma, local osteoporosis, osteomalacia, secondary osteoporosis or primary osteoporosis. In te study population (150 subjects), 80 percent of patients presenting with vertebral compression fractures had primary osteoporosis.
