WebScapholunate angle increased following distal radial fracture. Reduction of the fracture improved scapholunate angle, and this was most strongly related to change in dorsal tilt. We conclude that scaphoid flexion is likely to compensate for the dorsal tilt of the lunate as an attempt to counter its dorsal tilt, and to stabilize the wrist to maintain hand function.
