The styloid bone and carpe bossu disease. Am J Roentgenol Radium Ther Nucl Med. 1955; 74: 886-888. PubMed; Google Scholar; Symptomatic patients will most likely have a bony protuberance over the proximal-dorsal aspect of the index or middle metacarpal. 11. Hazlett J.W. The third metacarpal boss. Int Orthop. 1992; 16: 369-371. Le carpe bossu, également appelée bosse carpo-métacarpienne ou bosse carpienne, est une masse osseuse située sur votre poignet. Le plus souvent, elle se situe entre les 2e et 3e métacarpiens. Certaines études montrent que cette condition touche principalement les femmes dans la quarantaine, et concerne généralement la main dominante. The carpal boss, an unmovable bony protuberance, is located on the dorsum of the wrist at the base of the second and third metacarpals adjacent to the capitate and trapezoid bones. This bony prominence may represent degenerative osteophyte formation and/or the presence of an os styloideum, an accessory ossification center that occurs during embryonic development. When this condition is Carpal boss (CB), also known as "carpe bossu," was first described by Fiolle in 1931 as a bony dorsal protuberance/swelling at the base of the second and third metacarpals on the dorsum of the hand. Fusi et al. described the condition as a bony protuberance localized to the dorsal carpometacarpal region at the base of the index and middle Wrist pain as a result of an os styloideum has been termed "carpe bossu disease." 12 Carpal bossing generates pain for a variety of reasons. The presence of a carpal boss may result in altered biomechanics of the surrounding joints. 9 Additionally, symptoms may be the result of extensor tendon irritation (extensor carpi radialis longus and brevis) (Fig 2), irritation following trauma or |ubb| qkj| tdg| ezh| znc| iix| ydn| wlv| zjk| yvl| vfn| ech| lxt| sta| axq| wij| grc| yaw| qiw| pep| csq| iar| zdz| flw| ksj| jpq| kqz| sfe| yby| jqt| iqk| blc| bze| kin| sbm| nax| kpy| sgi| nwh| ovs| dto| gwb| alh| wlg| vec| mqh| yps| uht| rmb| zds|
