Abstract:

BACKGROUND: Traditional pedicle screw internal fixation combined with posterolateral lumbar fusion in the treatment of senile thoracolumbar burst fracture are easily to occur reset angle, high loss, delayed nerve damage and internal fixation loosening.
OBJECTIVE: To investigate the method and effect of transpedicular bone graft combined with pedicle screw internal fixation on the treatment of senile thoracolumbar fracture.
METHODS: Totally 32 patients who were more than 60 years old with thoracolumbar burst fracture were treated by posterior pedicle fixation combined with grafting through the injured pedicle. Height of fractured vertebrae, Cobb angle, occupying of spinal canal, neuropathic function, lumbar and back pain were measured and analyzed preoperatively, postoperatively and during the follow up period.
RESULTS AND CONCLUSION: All the patients were followed-up over 6 months. The internal fixation was not break or loose, the height of fractured vertebrae, the Cobb angle, the occupying of spinal canal, the neuropathic function, lumbar and back pain improved obviously, and the height of fractured vertebrae, the Cobb angle and the occupying of spinal canal were not obviously lose. It is indicated that application of transpedicular bone graft combined with posterior pedicle screw internal fixation is an effective method in treatment of senile thoracolumbar burst fracture, it can restore the height and strength of the vertebral body, and immediately increase vertebral bone content and the stability of the spine, and reduce the possibility of breaking nail, breaking rod, the loss of height and other complications, which are caused by stress.
