Core Tip

Core Tip: To the best of our knowledge, this case report introduces a new insight for the clinical application of three-dimensional printing technology in the treatment of cubitus varus deformity. Successful outcome of cubitus varus deformity correction is dependent upon precise preoperative planning and the accuracy of osteotomy and fixation. The treatment procedure itself can be performed safely, with high chance of alignment correction by means of three-dimensional printing technology to generate a well-designed customized osteotomy guide and patient-matched plate.
