Decompression and luque rectangle fusion for degenerative spondylolisthesis

Detailed follow-up at an average of 21.3 months is reported for 24 patients undergoing decompression and fusion with the Luque rectangle as a tension band device for spinal stenosis secondary to degenerative spondylolisthesis. Leg pain and back pain were improved at rates of 91% and 90%, respectively. The average distance walked increased from 1.1 blocks preoperatively to 6.8 blocks postoperatively. The fusion rate was 96%, and minimal slip progression was observed. The instrumentation is simple to perform and appears to have few complications.
