A follow-up study of 12 patients who had had surgical treatment for lumbosacral spondylolisthesis is reported. From a series of 12 patients, 7 patients were treated by reduction and fusion with or without instrumentation. These methods involved preliminary modified Vidal traction followed by anterior interbody fusion. Four patients were treated by anterior interbody fusion in situ, and the other one patient was treated by posterior decompression and posterolateral intertransverse fusion.
