Clinical Example: Congenital capitate malformation with capitate trapezoid
articulation and scapholunate diastasis
| This patient was evaluated for wrist
pain following a wrist sprain. |

| 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. |
