ABSTRACT
<p><b>OBJECTIVE</b>To clarify the abduction angle and needle insertion point of unilateral percutaneous vertebroplasty by measuring the related parameters of lower thoracic spine and lumbar vertebrae.</p><p><b>METHODS</b>Forty normal adults were included in the study, there were 17 males and 23 females. They were scanned by CT with thickness of 1 mm on T10-L5. The coross-section figures of pedicle of vertebral arch, zygapophysial joints, transverse process were choosed, and the maximal and minimal angle of transpedicular puncture, the puncture distance to posterior midline were measured by the image processing software of CT.</p><p><b>RESULTS</b>The data of pucturing angle and point distance had a increasingly trend from T10 to L5 in overall, including a slight decrease from T10 to T12, then was gradually increased until L5, where the maximum was got. According to the measurement, the unilateral percutaneous vertebroplasty were performed, and postoperative Cobb angle of 60 patients were obviously corrected, VAS had significantly decreased(<0.05).</p><p><b>CONCLUSIONS</b>Preoperative measurement of relevant parameters can guide the operation, improve the successful rate of unilateral puncture.</p>
