patients with a non/minimal displaced distal radius fracture (dorsal angulation <15°, volar tilt <20°, radial inclination >15°, ulnar positive variance <5 mm and an articular step off <2 mm).

No fracture is identified ... lateral radiographs of the distal forearm show osteosclerosis and collapse of the lunate consistent with avascular necrosis related to ulnar minus variance.
