<jats:title>Abstract</jats:title><jats:sec><jats:title>Background</jats:title><jats:p>The accuracy of three‐dimensional (3‐D) corrective osteotomy using a patient‐specific osteotomy guide and bone plate based on computer simulation was investigated.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>Six fresh‐frozen cadaver upper limbs were used. A patient‐specific osteotomy guide designed to realize a preplanned osteotomy was set on the distal humerus and distal radius, and the error in the setting location was evaluated. After the osteotomy, the surgical site was fixed using a patient‐specific bone plate designed to exactly fit the anatomical shape of the postoperative bone model. The postoperative results were compared with the preoperative simulation.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>The errors in the guide location on the humerus and radius were <1.5° and 1.0 mm and <1.0° and 1.0 mm, respectively. The plate fixation errors of the humerus and radius were <2.0° and 1.5 mm and <1.0° and 1.0 mm, respectively.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>The system is sufficiently feasible to realize precise 3‐D deformity correction of a limb.
