carpal bone

One of the eight wrist bones, which are aligned in two rows. The proximal row contains (from the thumb to the little finger) the scaphoid, lunate, triquetral, and pisiform bones. The distal row contains (from thumb to little finger) the trapezium, trapezoid, capitate, and hamate bones.

To decrease the error rate, the system applied the carpal bone information for subjects below 8 years using a fuzzy membership function.
Indeed Afifi and Lu (2011) have previously commented that the overlapping of the carpal bones makes plain radiographs difficult to interpret and this has been supported by previous authors (Sadowski and Montilla, 2008).
(2,3,7) Manual workers tend to have more repetitive trauma to the carpal bones leading to degenerative changes and subsequent loss of lunate blood supply.
In this case, not only scaphoid fracture and rupture of scapholunate ligaments were seen, but also excessive displacement due to severity of trauma resulted in carpal bones free of any ligamentous attachment.
These carpal bones in turn articulate with five metacarpal bones.
Scaphoid fractures of the wrist are common and account for 71% of all carpal bone fractures.
