Abstract
Corrective osteotomy for malunited fractures of the upper extremity remains a challenging procedure. Anatomical correction is the key to good clinical outcome after corrective osteotomy for malunited fractures, especially in cases of the upper extremity. To make a precise deformity correction in malunion, we have developed a computer-assisted system for corrective surgery, including a three-dimensional (3-D) program and a patient specific instrument (PMI), and investigated the results of corrective surgery for malunited fractures of the distal radius (MFRD), forearm diaphyses (MFFD) and distal humerus (cubitus varus deformity: CVD) with the use of this technology.

Corrective osteotomy was performed with the use of the PMI followed by internal fixation applied with plates and screws (MFRD, MFFD and adult CVD) or with Kirschner wires (pediatric CVD)
