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

Abstract

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.

Clinical Radiographic Features of the Wrist Without Osteoarthritis and Its Relations to Age and Sex in Japanese

“…15 But this study has several limitations. The first is that several participants enrolled in this study had some type of wrist problem without OA.…”

“…The relation between UV and age was the same as reported by Nakamura et al 14 Our results showed that UV increased and RI decreased with age were consistent with previous reports. 15 , 21 Using Pearson's coefficient, Katayama et al 15 analysed eight parameters (sex, age, RI, UV, CHR, VT, RLA, RSA) and the presence or absence of OA at the ulnar wrist joint. They then performed a multivariate logistic regression analysis, which revealed that UV had the highest significant correlation with OA of the DRUJ.…”

“…They then performed a multivariate logistic regression analysis, which revealed that UV had the highest significant correlation with OA of the DRUJ. 15 The increase of UV with age caused a significant increase in articular pressure at the DRUJ and ulnolunate joint, leading to OA of the DRUJ. 22 , 23 Furthermore, Katayama et al found that RI had the highest significant correlation with OA of the radial wrist joint.…”

“…The lateral radiographic criteria for OA of the wrist were defined as the presence of osteophytes in the volar or dorsal margin of the distal radioulnar joint (DRUJ), radiocarpal joint, and mid-carpal joint. 15 Participants were also excluded if they presented with: (1) Fractures or malunions of the radius, ulna, carpal bones, or metacarpal bones; (2) rheumatoid arthritis, dialysis-related arthritis, or other systemic arthritic conditions; (3) avascular necrosis of the carpus; (4) congenital deformities; (5) soft tissue tumour with an abnormal shadow. All patients were checked based on both the radiographic findings and clinical records to avoid the measurements of inadequate radiographs.…”

Artrosis de la articulación radiocubital distal

“…La artrosis de la ARCD puede deberse, al igual que en otras áreas anatómicas, tanto a causas primarias como a causas secundarias. La artrosis primaria es más común en mujeres y se asocia con una varianza cubital positiva 1 . Las causas secundarias son muy numerosas, pero tienen como denominador común la incongruencia y/o la inestabilidad de la articulación como resultado de agresiones directas o indirectas (fracturas de extremidad distal del radio, lesiones de los ligamentos radiocubitales distales, infecciones, artritis reumatoide, etc.…”
