Abstract

Transpedicular Screw fixation and Harrington distraction rod are effective means of managing unstable thoracolumbar fracture and fracture dislocation. The authors analysed the 52patients who were treated with above 2methods from March 1986 to February 1993. The results were as follows: 1. Most of patients were in 5th decade compare to younger group and most common cause of injury was fall down, but traffic accident is increasing. 2. The most commonly involved sites were T12and L1 vertebrae and most common type of injury is bursting fracture. 3. Postoperative anterior and posterior column of vertebrae body correction rate were 35.0%/34.4% in ISF group and 29.3%/27.9% in Harrington group. Postoperative correction loss rate were 0.13/0.04 in ISF group and 0.06/0.04 in Harrington group. 4. Postoperative correction of kyphosis angle were average 18 in ISF goup and average 15° in Harrington group. Loss of correction angle was average 23° in ISF group and average 4.4° in Harrington group. 5. Range of spinal fixation was average 3.1 segments in ISF group and average 6.2 segments in Harrington group. 6. There was no significant difference in neurologic recovery between ISF group and Harrington group. The patients who had been recovered neurologically more than 1 grade were 28.6% in Harrington group and 29.2% in ISF group. 7. ISF has some benefit in spnal vertebral body height correction and in maintenance of correction compare to Harrington group. Nevertheless disadvantages of ISF group such as long operative time and possibility of cord compression by pedicular screw, ISF has advantages of almost anatomical reduction and the least spinal fusion.
