Representative radiographs and computed tomography (CT) findings demonstrating a typical example of pseudoarthrosis following osteoporotic compression fracture. (A, B) Preoperative flexion-extension lateral radiographs demonstrating significant instability and kyphotic deformity of the vertebral body at T12 and L1. (C) A postoperative radiograph obtained immediately after procedure A revealing excellent augmentation of the vertebral body and significant correction of the kyphotic deformity of 30° in the Cobb measurement. (D) At 3 months after surgery, the correction is relatively decreased because the CPC mass was partially broken and displaced anteriorly. (E, F) A postoperative CT finding obtained one week after surgery demonstrating the preoperative defect filled with calcium phosphate cement at T12 (E) and L1 (F).
