RESUMO
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.

Tibial tubercle avulsion fractures are uncommon injuries that are seen mostly in adolescent male patients during athletic activities. The mechanism of injury usually involves a strong eccentric contraction of the quadriceps femoris muscle when the proximal tibial physis is closing, leading to failure of the physis at the patellar tendon insertion. The treatment of patients with tibial tubercle avulsion fractures depends on the fracture pattern; it can be conservative with immobilization in a long leg cast in extension for 6 weeks with minimal displacement (< 2 mm) and/or acceptable displacement after closed reduction/cast application. Or it can be surgical. This article presents a 14-year-old boy with an Ogden type IIIB tibial tubercle avulsion fracture that was misdiagnosed on radiographs at presentation as type IB. Open reduction and cannulated screw osteosynthesis was done. The outcome was excellent after a 12-week rehabilitation protocol.
