Abstract:
BACKGROUND:The clinical treatment of thoracolumbar fractures and dislocation of the patients can be treated with pedicle screw fixation through adjacent vertebral segments. With the increased incidence of disease, many problems were found such as fixator loosening and breakage. OBJECTIVE:To compare the effectiveness of vertebral pedicle screw fixation versus cross-segment pedicle screw fixation for thoracolumbar vertebral fracture and dislocation. METHODS:100 patients with thoracolumbar vertebral fracture and dislocation were chosen in the 474 Hospital of Chinese PLA from February 2013 to May 2014. The patients were randomly assigned to two groups (n=50). Patients in the control group were treated with cross-segment pedicle screw fixation, and those in the observation group were treated with the vertebral pedicle screw fixation. Parameters of imaging were compared and observed. RESULTS AND CONCLUSION: Significant differences in the spinal canal area improvement value and internal fixation failure rate were detected between the two groups (P < 0.05), and the observation group was better than the control group. The height ratio of anterior border of the vertebral body was higher at 12 months after treatment than that pretreatment, but Cobb angle was lower than pretreatment (P < 0.05). These data indicate that compared with cross-segment pedicle screw fixation, vertebral pedicle screw short-segment fixation for thoracolumbar vertebral fracture and dislocation obtains more ideal outcomes and higher safety. It is more in line with biomechanics at the same time ensuring the fixing strength.
