Abstract
Atypical femoral fracture related to a long-term bisphosphonate therapy has commonly been reported; however, a fracture at the site other than the femur has rarely been reported to date. Herein, we report a case of a patient on long-term bisphosphonate therapy who presented atypical tibial insufficiency fracture at the anterolateral aspect of diaphysis, without trauma. We, for the first time in Korea, present this case with a literature review.

Figures and Tables
Fig. 1
Preoperative radiograph shows atypical tibial diaphyseal fracture (white arrows), including periosteal reaction, endosteal thickening, and a radiolucent fracture line.
Fig. 2
Preoperative computed tomography shows periosteal reaction, cortical thickening, and transverse fracture line (white arrows).
Fig. 3
Bone scan of this patient shows increased uptake (arrow) at the anterolateral area of tibial diaphysis.
Fig. 4
Using intramedullary nailing, operation was performed.
Fig. 5
The radiographs of tibia taken eight months after the operation show callus formation at the fracture site, with a diminished gap of fracture.
