Preoperative Three-Dimensional Simulation of Osteotomy for Correction of Malunion of Both Bones of Forearm: A Case Report

초록

Corrective osteotomy of malunion of both forearm bones is a challenging procedure because it needs accurate angular and rotational correction of both bones. Recent advances in three-dimensional (3D) printing techniques have shown promising results in the correction of complex deformities. We report a patient with malunion of both bones of the forearm in whom we determined site and degree of correction required based on the computed tomography images of the affected side and mirrored images of the contralateral healthy side. We then created 3D printed sawbones and simulated osteotomy to confirm stable dynamic forearm rotation. This method enabled satisfactory restoration of anatomical and functional outcomes. Preoperative dynamic motion simulation using 3D printed anatomic bone model is helpful for complex corrective osteotomy of forearm fracture malunion.
