Surgical treatment of spondylolisthesis with SOCON instrumentation.

OBJECTIVE

To observe the clinical outcomes of using a new instrumentation SOCON system in the treatment of degenerative spondylolisthesis.

METHODS

Retrospective clinical and roentgenograph review of 21 patients who suffered from degenerative spondylolisthesis with spinal stenosis treated by decompression, posterolateral intertransverse arthrodesis, and with transpedicle instrumentation of SOCON system.

RESULTS

Nineteen of 21 patients were completely recovery from their preoperative symptoms, 17 of 18 cases with grade one slippage reduced to normal spine alignment, 2 cases of grade two slippage fully reduced, and one case of grade two spondylolisthesis got 70% reduction. Post-operative satisfactory rate was 90.5%. Pain relief was 90.5%. Neither infection nor neurologic complication occurred in this series.

CONCLUSION

Our short time follow-up and limited cases showed satisfactory preliminary result of surgical treatment of spondylolisthesis with SOCON instrumentation.
