 Computed tomography (CT) is recommended for routine use in the diagnosis of osteoporotic vertebral fractures. An evaluation of the CT scans and complementary radiographic studies of 61 patients with osteoporotic vertebral fracture are reported. Spinal fractures were divided into three categories by the CT scans:compression fractures, burst fractures, border-line burst fractures that demonstrated irregularity of posterior wall of vertebral body. The border-line burst fracture group demonstrated the most progression of vertebral wedge deformity and segmental kyphosis. The burst fracture and border-line brust fracture group demonstrated collapse of vertebral segmental height. Although it is difficult to differentiate between the compression fracture group and border-line burst fracture group by plain X-ray films, there is strong possibility that micro-fracture of posterior wall of vertebral body is present in the border-line burst fracture group. Therefore, the border-line burst fracture group should be treated as burst fracture. CT is recommended for routine use in the diagnosis whether micro-fracture of posterior wall is present.
