From 2004 to 2007, 34 cases were treated with extrapedicular screw fixation in Department of Orthopaedics, Third Affiliated Hospital of Sun Yat-sen University. The screw entry point, angle, depth and diameter were measured and defined on the thoracic vertebrae pedicle by CT thin-slice scan in standard prone for all cases before operation. The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle. The integrity of cortical bone around screws, the distance to segmental blood vessels and the penetration of cortex were observed after operation to evaluate the accuracy and safety of screw placement.
