1 Chart showing the distribution of vertebral osteonecrosis at different levels.
Chart showing the distribution of vertebral osteonecrosis at different levels. Changes of the content of affected vertebral bodies, intravertebral fluid only (blank bars), coexistence of both fluid and air (dot bars), and intravertebral air only (oblique line bars) are also shown. T12 (n = 40) and L1 (n = 36) were most often involved. Of 121 osteonecrotic vertebral bodies, 48 (39.7%) appeared with only intravertebral air, 47 (38.8%) appeared with only intravertebral fluid, and 26 (21.5%) appeared with both air and fluid. C.-W.
