Quantitative microfocal radiographic assessment of disease and progression in osteoarthritis of the hand.
Macroradiographic examination of the wrists and hands of 32 patients with osteoarthritis (OA) over an 18 month period showed that, compared with healthy control subjects, 44% of the patients had significant joint space narrowing at entry, which increased to 65%. Subchondral cortical thickness was greater in all patients at entry and increased with time. Osteophytes and juxtaarticular radiolucencies were present in all patients at study entry; by the end, osteophytes had increased in number and area, and juxtaarticular radiolucencies in area only. We conclude that in OA of the hand, bony changes have progressed significantly before joint space narrowing.
