[Computer-assisted planning and corrective osteotomy in distal radius malunion].
Corrective osteotomy of the malunited distal radius following fracture was performed in six patients using virtual planning and computer-assisted surgery. Radius joint angles and ulnar variance were assessed by CT scan and compared with the uninvolved wrist. Dorsal tilt was improved by 6 degrees, radial inclination by 3 degrees, radius rotation by 7 degrees and ulnar variance by 4.6 mm. Results were almost equivalent to the noninvolved radius. Corrective osteotomy in extraarticular malunited distal radius fracture was optimized by computer-assisted planning and surgery.
