We analyzed 44 cases of burst fractures on the thoracolumbar junction which were operated with posterior instrumentation technique at the Department of Chungnam University Hospital from 1988 to July 1995. Reduction of the spinal fragment through kyphosis correction and distraction were evaluated using conventional radiographs and CT imaging between postop., POD 6 months and POD 12months in 23 cases of burst tractures.
The purpose of this study was to evaluate the spinal canal remodeling using radiographic means.
The result were as follows :
1. The average kyphotic correction angle was 7.4˚ and there was no correlation between the reduction of retropulsed fragments and the amount of kyphotic angle correction.
2. There was significantly correlation between the amount of reduction of posterior vertebral body and amount of retropulsed fragment.
3. There was no correlation between the degree of canal compromise and the Denis type of thoracolumbar burst fractures.
4. There was significantly correlation between the shape of the patent portion of the spinal canal and neulologic deficits.
