A Surgical Technique for Corrective Osteotomy of a Complex Distal Humeral Deformity Using 3-Dimensional Printing Technology

Abstract

Corrective osteotomy for complex deformity correction is a challenging procedure, both in its planning and execution. 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.
