Abstract:
We analyzed 41 cases of burst fractures on the thoracolumbar junction which were operated with Kaneda and Cotrel-Dubousset implant at Chosun University Hospital between 1989 and 1993. The purpose of this study was to evaluate the radiologic sign, the amount of reduction, complications, and functional results. The results were as follows: 1. According to McGrorys Criteria to evaluate the posterior superior vertebral body angle of burst fractures, 33 out of 41 cases(80.5%) were positive and the average angle degree was 107.6°. 2. The average postoperative kyphotic correction was 15.4° in the Kaneda group and 13.8° in the C-D group. The average loss of correction at follow-up examination was 5° in the Kaneda group and 4.8° in the C-D group. 3. Indirect reduction was achieved in 10 cases(50%) and we obtained a good indirect reduction even though canal compromise was over 50%. 4. The pain at operative site was much more severe in the Kaneda group(6 cases) than in the C-D group(2 cases) and both groups experienced 2 cases each of implant failure. 5. According to Denis' pain and work scale, 28 cases(63.8%) had good and excellent, 8 cases had fair and 5 cases had poor results. In summary we recommend doing 1) a posterior instrumentation first for stability and indirect reduction, if it is not a severe neurologic symptom and 2) anterior decompression if it is a severe or progressive neurologic symptom.
