Fig. 1Intraoperative photographs show surgical approach (A), wedge osteotomy and wedge shaped iliac bone (B, C, D), and plate fixation (E).
Fig. 2
(A, B) Initial simple radiographs show unstable distal radius fracture. (C, D) Simple radiographs after external fixation and K-wire fixation show radial inclination of 20°, volar tilt 5°, and neutral ulnar variance. (E, F) Simple radiographs after removal of external fixation and K-wire show the volarly malunited distal radius with volar tilt of 25°, 12° radial inclination, 3 mm ulnar positive variance. (G, H) Simple radiographs after open wedge osteotomy show a good alignment of distal radius with volar tilt of 5°, 25° radial inclination, 0 mm ulnar variance.
Fig. 3
(A, B) Initial simple radiographs show Colles' fracture with ulnar styloid fracture. (C, D) Simple radiographs after closed reduction and splinting show a good alignment of distal radius. (E, F) At 2 months after trauma, simple radiographs show volarly displaced distal radius fracture with volar tilt of 30°, 15° radial inclination, 5 mm ulnar positive variance. (G, H) Simple radiographs after open wedge osteotomy show a good alignment of distal radius with volar tilt of 10°, 23° radial inclination, 0 mm ulnar variance.
