(a) The left hand appears to be mildly hypoplastic compared to the right hand. (b) Dorsal bowing of the forearm and dorsal prominence of the ulnar head.

At first presentation, her wrist and hand translated the volar side relative to the longitudinal axis of the forearm; the ulnar head projected dorsally (Figure 1(a) and (b)).
(a) Posteroanterior radiography showed 30  ulnar tilting of the distal articular surface of the radius and 5.7 mm lunate proximal subsidence and a distal radial notch in the left wrist. Lateral radiography showed 50  palmar tilting of the distal articular surface of the radius in the left wrist. (b) Posteroanterior radiograph showed 53  ulnar tilting of the distal articular surface of the radius and 2.0 mm lunate proximal subsidence and no distal radial notch in the right wrist. Lateral radiograph showed 80  palmar tilting of the distal articular surface of the radius in the right wrist.

The posteroanterior and lateral radiograph of left wrist showed a 30  ulnar tilting angle, 5.7 mm lunate proximal subsidence and a distal radial notch and 50  palmar tilt angle (Figure 2(a)). On the right side were a 53  ulnar tilting angle, 2.0 mm lunate proximal subsidence and no distal radial notch and 80  palmar tilt angle (Figure 2(b)).
It was planned that the wedge bone with an angle of the apex of the wedge of 20  should be resected from the distal metaphysis of radius and be put reversely into the bone cutting site to correct the radial inclination and dorsal tilt.
