Radiographic assessment of osteoarthritis.
Osteoarthritis is one of the most prevalent and disabling chronic conditions affecting older adults and a significant public health problem among adults of working age. As the bulk of the U.S. population ages, the prevalence of osteoarthritis is expected to rise. Although the incidence of osteoarthritis increases with age, the condition is not a normal part of the aging process. More severe symptoms tend to occur in the radiographically more advanced stage of the disease; however, considerable discrepancy may exist between symptoms and the radiographic stage. Roentgenograms of involved joints may be useful in confirming the diagnosis of osteoarthritis, assessing the severity of the disease, reassuring the patient and excluding other pathologic conditions. The diagnosis of osteoarthritis is based primarily on the history and physical examination, but radiographic findings, including asymmetric joint space narrowing, subchondral sclerosis, osteophyte formation, subluxation and distribution patterns of osteoarthritic changes, can be helpful when the diagnosis is in question.
