Abstract:
Objective To observe the early clinical outcome of the lumbar spondylolisthesis treated with decompressive laminetomy, intertransverse process arthrodesis with bone grafting, interbody fusion cage and solid transpedicle SOCON instrumentation. Methods From December 1997 to December 1999, 38 cases of lumbar spondylolisthesis were treated with decompression for spine canal stenosis. And intertransverse process arthrodesis was done by means of bone chip grafting obtained from the iliac crest, or the interbody fusion cage and the SOCON system. According to Meyerding classfication of lumbar spondylolisthesis, 32 cases were classified as degree 1, 6 cases as degree 2. The levels of lumbar spondylolisthesis was between L 4 and L5 in 29 patients and between L 5 and S 1 in 9 cases. Results The patients were followed up from 14 to 26 months with an average of 18.2 months. The results showed that the pre operative clinical symptoms disappeared completely in 31 of 38 patients. Pain relief was seen in 81.6%. 32 cases with degree 1 and 4 of 6 cases with degree 2 obtained the complete reduction of the slide intervertebral body. Anatomical reduction rate was 94.7%. The other 2 cases of the degree 2 patients obtained 90% of reduction. No infection or neurologic complication occurred in this series. Conclusion Treatment of lumbar spondylolisthesis with SOCON system has satisfactory reduction rate and excellent clinical results.
