Abstract
Osteoblastoma is rare, benign, bone-forming tumor that often occur in the spine. There are few reports of osteoblastomas resulting in pathologic fractures involving long bones. Authos report a unique case of a pathologic fracture due to an osteoblastoma of the humerus shaft. The tumor was treated successfully by curettage, intramedullary nailing and bone allograft.

Figure 1.
Initial radiographs show a transverse humerus shaft fracture with displacement. At the fracture site, a radiopaque lesion is identified in the medullary space of the proximal fragment of the humerus (white arrows).
Figure 2.
Enhanced MRI shows a focal sclerotic lesion involving both the medullary and cortical portions around the fracture site and a small enhancing portion at the periphery, suggesting a bone-forming tumor (white arrows).
