Three-Dimensional-Printed Proximal Radial Plate for Radial Reconstruction after Tumor Resection: Case Report and Literature Review.

Tumors in proximal radius are rare. Fibrous dysplasia (FD) describes a benign tumor of fibrous tissue that rarely occurs in proximal radius. We present the case of a 26-yr-old male with monostotic proximal radius FD. Follow-up forearm radiographs showed progressive radial cortex expansion and thinning. The patient was treated with lesion curettage, a synthetic bone graft substitute, and fixation with a three-dimensional (3D)-printed proximal radial plate. At 18-mo follow-up, forearm radiographs showed graft incorporation and the 3D-printed plate in place without signs of loosening. The patient was pain-free, had full range of motion in the elbow, and no restrictions to his daily activities.
