Abstract

The authors retrospectively analyzed 17 cases of posterior lumbar interbody fusion with Threaded Fusion Cage(TFC) at the Department of Neurosurgery, Chungbuk National University Hospital from May 1994 to June 1995. The objective of this study is to verify the adventages of posterior lumbar interbody fusion with TFC to the usual posterolateral fusion with pedicle screw instrumentation. Postoperative clinical and radiological change is shown by Gill's criteria and neutral L-spine lateral measurement. The results are as follows:The disc space height was increased(8%), the fusion rate was 85%, the postoperative slip was remarkable in the spondylolisthesis group, the TFC angle after operation was changed slightly, especially in spondylolisthesis group, and their outcome was excellent(0%), good(53%), fair(47%), poor(0%). The complications were transient foot drop(1 case) and TFC migration(1 case). This change was not statistically significant in different preoperative diagnoses and methods of laminectomy. In conclusion, posterior lumbar interbody fusion with TFC was a good method in spinal stenosis and HIVD, but the result of spondylolisthesis was found to be less favorable than previously reported. Further controlled trials are therefore necessary to determine the efficacy of posterior lumbar interbody fusion with TFC in patients who were diagnosed with spondylolisthesis.
