Distribution of primary osteoarthritis in the ulnar aspect of the wrist and the factors that are correlated with ulnar wrist osteoarthritis: a cross-sectional study.

International Skeletal Society

OBJECTIVE: The purpose of this cross-sectional study was to identify the distribution of primary osteoarthritis (OA) in the ulnar aspect of the wrist, and analyze the factors correlated with OA at this site.MATERIALS AND METHODS: A total of 1,128 cases of skeletally mature Japanese patients were collected over a 3-year period. We analyzed the posteroanterior and lateral wrist radiographs of these patients for the presence of primary OA in the ulnar aspect of the wrist, including the distal radioulnar (DRUJ), radiolunate, ulnolunate, lunotriquetral, triquetrohamate, lunohamate, and lunocapitate joints. All joints were examined for the frequency of primary OA. Multivariate logistic regression was used to investigate the factors correlated with the presence of degenerative arthritis in the ulnar aspect of the wrist joint.RESULTS: Primary OA of the ulnar wrist was identified in 145 out of 1,128 cases (12.8 %). Degenerative changes were most frequently identified in the DRUJ (12.3 %), followed by the ulnolunate joint (8.1 %). Variations in radial inclination (RI), carpal height ratio (CHR), and ulnar variance (UV) correlated with OA of the ulnar aspect of the wrist, with variations in UV showing the highest correlation.CONCLUSION: Primary OA of the ulnar wrist was most frequent in the DRUJ and second most frequent in the ulnolunate joint. UV correlated most with OA in the ulnar aspect of the wrist.;博士(医学)・乙1328号・平成26年3月17日;The definitive version is available at " http://dx.doi.org/10.1007/s00256-013-1665-9 ";開始ページ : 1253;終了ページ : 1258;PubMed番号 : http://www.ncbi.nlm.nih.gov/pubmed/23775319
