BackgroundVarious methods of two or three-dimensional (3D) corrective osteotomy for cubitus varus deformity have been reported. However, whether 3D correction is necessary controversial because technical difficulties and surgical complications. This study introduced simulations printing technology against deformities. Moreover, recent studies on the application these technologies were reviewed.MethodsThe amount was calculated based difference in shape between affected side contralateral normal side. Patient-matched instruments created to perform actual surgery as simulated. Further, a performed using patient-matched pediatric adolescent patients. The humerus-elbow-wrist angle, tilting elbow ranges motion evaluated.ResultsHumerus-elbow-wrist angle corrected from −21° 14° 30° 43°, respectively, patient −18° 10° 20° 40°, patient. flexion extension angles changed 130° 140° 10°, 120° 15° 0°, patient.ConclusionThe computer use are reliable can facilitate an accurate safe correction. These simplify complexity procedures contribute standardization treatment deformity. Various reviewed. evaluated. Humerus-elbow-wrist
