Abstract:

BACKGROUND: Short-segment pedicle screw technology has been extensively used in the treatment and repair of thoracolumbar burst fractures in the clinic. However, it requires further investigations whether bone graft through unilateral pedicle channel has superiority.
OBJECTIVE: To observe the perioperative effects on thoracolumbar burst fractures posterior by bone graft through unilateral pedicle channel with short pedicle screw segment fixation.
METHODS: Clinical data of 57 cases of thoracolumbar burst fractures without neurological symptoms treated by short segment pedicle screw internal fixation therapeutic method at the Department of Orthopedics, The First  People’s Hospital of Yinchuan City from January 2009 to December 2013 were retrospectively analyzed. According to therapeutic methods, they were divided into three groups: pedicle screw fixation through injured vertebrae (n=21), unilateral pedicle screw fixation with vertebrae pedicle screw (n=19), and the short segment pedicle screw fixation with unilateral pedicle screw fixation and bone graft through pedicle channel (n=17). We observed the changes in operation time, the blood loss volume in operation, postoperative drainage blood (at the period of removing the drainage tube), injured vertebrae height’s ratio, the Cobb’s angel of injured vertebrae sagittal plane, vertebral canal encroachment rate and visual analog scale.
RESULTS AND CONCLUSION: (1) The unilateral pedicle screw fixation and bone graft by pedicle channel could prolong operation time and increase postoperative drainage blood volume (P < 0.05). (2) Three operation methods improved vertebral body height. (3)There were no significant differences in Cobb’s angle postoperation among the three groups (P > 0.05). These data suggested that the bone graft through pedicle channel was not the factors to improve the spine kyphosis. (4) Bone graft by pedical channel improved vertebrae channel value. (5) Bone graft through pedicle channel combined with screw implantation could improve pain after treatment. These findings indicated that the therapeutic technology of short pedicle screw fixation on thoracolumbar vertebral burst fracture with unilateral pedicle fixation and bone graft through pedicle channel is a safe reliable operation method.
