Clinical Research In The Transpedicular Intracorporeal Grafting In The Treatment Of Thoracolumbar Burst Fractures

Objective: Evaluation the clinical effect of thoracolumbar burst fractures treated byinjured vertebral transpedicular intracorporeal bone grafting plus pedicle crew fixation，inorder to provide scientific evidence for clinical use.Methods:32cases of thoracolumbar burst fracture patients in our department fromSeptember2008to October2013were treated, of which16cases were within the injuredvertebrae pedicle graft combined with pedicle screw fixation,16cases of the using asimple posterior reduction and internal fixation of pedicle screws, posterolateral fusionsurgery. Respectively, before surgery, when the line after1week and final follow up X-rayand CT examination, the leading edge were measured vertebral body compression ratio,spinal sagittal Cobb angle, spinal canal and make a statistical analysis of the rate of.Morphological changes in the vertebral bone filling, fracture healing. Frank gradingstandards were to assess neurological function, Charles criteria to assess clinical efficacy.Results:30cases were received an effective follow-up.Each group have15cases. Therewere no significant differences between the2groups in either the anterior body height orCobb angle correction in immediate post operation.(P>0.05).Average anterior vertebralheight restoration of around92%, Cobb’s angle decreased by about20°.But the effect ofthe composite was injured vertebrae pedicle graft combined much better than anothergroup(P <0.01), the follow-up of a half year outside of bone after varying degrees ofvertebral height and Cobb’s angle correction are loss (5.8%/6°). While the compositepedicle graft did not find a significant loss of correction and internal fixation complications.However, no significant difference in the two procedures to restore spinal cord function.Conclusion: After the injured vertebral pedicle bone graft and posterolateral vertebralbone more able to immediately increase the capacity and stability in the former spinalcolumn compression, more in line with biomechanics, effectively filling the vertebral bonedefects, preventing far lost and orthopedic complications occur within a fixed, worthy ofpromotion.
