Outcome of thoracolumbar fracture with spinal cord injury treated with short-segment pedicle instrumentation / 中国矫形外科杂志

ABSTRACT

[Objective]To evaluate the outcome of thoracolumbar fracture with spinal cord injury treated with short-segment pedicle instrumentation.[Method]47 cases of thoracolumbar fracture with spinal cord injury from 1999 to 2004 in our department were collected,all of them were treated with short-segment pedicle instrumentation.The radiologic,neurologic,and functional outcome were assessed.[Result]All of the 47 cases were followed up,the mean follow-up were 51.9 months(18~ 86 months),the average of vertebral anterior and posterior height were corrected from 43.6%,71.4% to 92.2%,96.4%;and 88.3%,93.1% at the last follow-up separately.The Cobb's angle were corrected from 23.5?to 4.3?,and 8.8? at the last follow-up.62.8% of the vertebral canal was occupied pre-operation,and 11.4% post-operation,6.2% at last follow-up.There was significant deference in targets between pre-operation and post-operation(P0.05).Neurologic status improved at least 1 Frankel grade in the patients who had preoperative incomplete paraplegia.61.7% of patients returned to work.[Conclusion]Short-segment pedicle instrumentation can provide good reduction,strong fixation,complete decompression and fusion.The treatment outcome is good.Moreover,it is a less traumatic,simple and safe technique.
