Plain films demonstrate an unusual capitate contour, articulating with the proximal trapezoid. There is a wide scapholunate interval. |
The scapholunate angle is abnormal, about 80 degrees. |
Radial and ulnar deviation views show minimal additional scapholunate widening in ulnar deviation. |
The opposite wrist is similar. This anatomy probably represents congenital carpal coalition between the capitate and an os centrale. |
