Osteoarthritis of the first carpometacarpal joint: a study of radiology and clinical epidemiology. Results from the Copenhagen Osteoarthritis Study.
The radiological and epidemiological data from the Copenhagen Osteoarthritis Study (COS) were analysed in order to assess the prevalence of osteoarthritis (OA) of the first carpometacarpal joint (CMCJ). Another aim of the study was to analyse relationships between radiologic CMCJ OA and self-reported pain. The third aim was to analyse if additional information could be obtained applying a new method of correlating individual radiological features to self-reported pain, compared to Kellgren and Lawrence's (K-L's) radiologic OA classification. ⋯ Radiological degenerative changes in the CMCJ by age especially among women are quite common. However, it is demonstrated that global radiologic classifications of OA of the CMCJ have serious limitations in epidemiological studies. Not all cases fit into classification based on the K-L-atlas. Among the radiological features, subchondral sclerosis is significantly related to self-reported pain. Specific radiologic data should be incorporated in epidemiological studies on hand OA.
