Traditional planning techniques, particularly when applied to periarticular deformity, are generally inaccurate and the outcome of subsequent osteotomy may be suboptimal. In this described technique, 3-dimensional printed models were generated from preoperative computed tomographic scans to assist in both the planning and execution of a distal humeral osteotomy. A single case is described of cubitus valgus of 40 degrees with fixed flexion deformity following nonunion of a fracture of the lateral condyle of the humerus.
