The operative treatment of burst fracture in thoraco-lumbar spine, such as anterior decompression and fusion, posterior fusion or combined method, is determined by neurologic deficit and instability. Sixteen burst fractures were treated with anterior decompression and anterior fusion using Kaneda instrument from Aug. '1988 to Dec'. 1989. The results are as follows, 1. The most common type of burst fracture was type B by Denis classification. 2. There was no relationship between canal compromise and neurologic deficit. 3. Among 10 cases with neurologic deficit, 5 cases with incomplete neurologic deficit improved by 1.2 Frankel grade, but 4 cases with complete neurologic deficit did not improve. 4. Kyphotic deformity was corrected from 22.3°preoperativiely to 10.6°postoperatively and 11. 9°at the end of follow-up. 5. Height of anterior column was corrected from 55.4% preoperatively to 87.2% postoperatively. 6. Complications were 1 case of breakage of screw and 1 case of myositis ossificans.
