| 摘 要： | The pedicle screws and the technology of insertion be- came one of the most important methods for the treat- ment of the spine diseases. In clinical practice, pedicle screws might be misplaced and cause severe complica- tions. The purpose of this study was to obtain the data by three-dimensional reconstruction of multi-slice spiral CT (MSCT) to guide the placement of pedicle screws. 1 MATERIALS AND METHODS 1.1 Materials Two embalmed human cadaveric thoracic pedicle spines (T1-T10) w…

| Abstract: | To investigate the value of the guidance of three dimensional (3-D) reconstruction of multi-slice spiral CT (MSCT) for the placement of pedicle screws, the 3-D anatomical data of the thoracic pedicles were measured by MSCT in two embalmed human cadaveric thoracic pedicles spines (T1-T10) to guide the insertion of pedicle screws. After pulling the screws out, the pathways were filled with contrast media. The PW, PH, TSA and SSA of developed pathways were measured on the CT images and they were also measured on the real objects by caliper and goniometer. Analy- sis of variance demonstrated that the difference between the CT scans and real objects had no statis- tical significance (P>0.05). Moreover, the difference between pedicle axis and developed pathway also had no statistical significance (P>0.05). The data obtained from 3-D reconstruction of MSCT demonstrated that individualized standards, are not only accurate but also helpful for the successful placement of pedicle screws. |
